Ska man summera det långa inlägget så är frågan är det moderkortet eller processorn?

Har f n inte möjlighet att byta och testa men om någon har kunskaper och erfarenheter så lyssnar jag som ett elefantöra.

Bra tanke men tror inte det - har hela tiden haft MBM installerat med cpu-temp på 41-43 och fläkten är ansluten på rätt ställe.

Stäng av den automatiska omstarten vid fel
Index
En liten detalj man kan ändra på och få lite trevligare dator, är att stänga av den automatiska omstarten vid fel. Högerklicka på "Den här datorn" välj egenskaper (som när man tar fram enhetshanteraren) Välj fliken "Avancerat" och "Inställningar" i sektionen "Start och återställning". Klicka ur "Starta om automatiskt". Man kanske får en BSOD i stället men det är väl bättre att veta vad som händer.... (BSOD = Blue Screen Of Death, dvs blå döden på svenska).

Getting ready to install or reinstall Windows
These instructions are applicable for all VIA chipset motherboards. All the screenshots are taken from an install of Windows XP but if you were installing an older version or Windows XP x64, the information would still be relevant and almost certainly detailed enough to assist with those operating systems also. Not much has changed with installing Windows over the years.

Please read the instructions first BEFORE you begin.

Before you do the installation or reinstall, visit the web site of your peripheral manufacturers and make sure you have the latest drivers as well as any VIA drivers you need. VIA drivers can be found here. If you are not sure what drivers you need, read over this article.

Back up anything you want on your hard drive. (You might back up by transferring files to a secondary hard drive, another PC or burning files to CD or DVD or copying files to a USB hard drive).

I would also recommend that you visit your motherboard manufacturer's web site to make sure you have the most up to date BIOS or the BIOS most appropriate for your system set up. If you are not sure what motherboard make and model you have, read over this article.

Take out all devices except the video card, processor, memory, CD-rom and primary hard drive. (That is remove or unplug any audio cards, SSCI drives, secondary hard drives, secondary ROM drives, printers/scanners etc
Get the BIOS ready

On boot-up press delete to enter your BIOS.

Explanation: Press the power button on your PC and start hitting the Delete key. Your PC will start to go through the boot process and there will be a point where a message will display "Press Delete to Enter Setup" or something similar. On a lot of systems, if you blink you might miss it so you might as well just start hitting the Delete key as soon as you turn the PC on. On some older systems it might require that you press a different key like F2, but the majority use the Delete key these days. This will take you to your BIOS main menu. The BIOS is a set of routines stored on a BIOS memory chip that is on the motherboard. These routines allow the systems hardware components to operate on the basic level in order to install an operating system and/or boot an operating system.

BIOS do feature a graphical interface but they are very simple compared to modern operating systems. To navigate through a BIOS menu you normally use the arrow keys and press enter to select an option. The F keys are also often used. Most BIOS have a short key menu explanation near the bottom of the screen.



The main menu of the BIOS on the left is of a very common type - an AWARD BIOS. VIA reference BIOS are usually an AWARD BIOS so many VIA chipset-based boards also feature an AWARD BIOS. The rest of the BIOS screen shots in this article are from this BIOS. This particular one is from a VIA EPIA SP Mini-ITX Mainboard. The BIOS pictured on the right is much simpler with far less options. It is from a laptop. Most laptop BIOS are this simple type. In the bottom of the AWARD BIOS screen and the bottom right of the American Megatrends BIOS, you can see the legend key for navigating through the BIOS.

Load Failsafe Defaults

The first thing to do is to load Failsafe defaults. What this setting does is to fix all of the settings in BIOS to those programmed by the motherboard manufacturer to be tested and known to be stable and possibly even so stable that hardware will not perform at its best.




Under the AWARD BIOS, use your arrow keys to move over to "Failsafe Defaults" and press Enter to select the option (highlighted as per the above).




Type y and hit Enter to confirm your selection.

Set the First Boot Device

Secondly, set the first boot device to the CD-rom drive. You can normally find this option under "Advanced BIOS Features". A little later on you will put your Windows installation CD in the CD-rom drive and boot the PC. With the CD-rom set as the first boot device, the installation CD will be detected first instead of the hard drive.



To do this, again use the arrow keys to highlight the "Advanced BIOS Features" menu item and hit enter (as above).



Use your arrow keys to highlight "First Boot Device" which by default will probably be set to Floppy (as above). Hit enter.



This will bring up a little selection box so that you can select what should be the first boot device. Use the arrow keys to select CD-rom. To get back to the main menu of the BIOS, hit the ESC key.

Disable onboard peripherals

Disable any onboard peripheral devices that you do not intend to use. For example, if you have AC-97 sound but intend to use a third party sound card, disable onboard sound. If you have integrated video but use a third party video card, disable onboard VGA (etc).

In the AWARD BIOS, you can find these settings under Integrated Peripherals. Again, using the arrow keys, highlight this menu item and hit enter.

Here you can use the arrow keys to navigate up and down the list of peripherals. For most items the options will be Enable and Disable.

To change between these, hit enter and just like choosing the first boot device, use the arrow keys to switch between the options and hit enter.

Save and exit the BIOS.
Before you Save and Exit the BIOS, place the Windows Installation CD in the CD-rom drive. If you forget don't worry, just power down the system and then boot it up again, insert the CD-rom, power down again and then boot up. Either way what you need to do is boot the system with the Windows installation CD in the CD-rom drive.

Because you set the first boot device to be the CD-rom drive in the BIOS earlier, the installation disk will be detected and you will be given the option to "Press any key to boot from CD ..." This option is only available for about 4-5 seconds so stay on your toes. Press any key when you see it. If you miss it the BIOS will go on to the second boot device, which would probably be the hard drive. If a previous copy of Windows is installed on the hard drive it will load Windows. If it's a new hard drive the PC would simply reboot.

Windows will inspect the hardware in the system and then the Windows Setup screen will appear. Press ENTER to set up Windows.
Press F8 to accept the user agreement.

Along the bottom of the Windows Steup screen, several options will be given and then some detail of what files are being loaded. It is soon after the user agreement that an option to "Press F6 if you need to install any third party SCSI or RAID driver..." will appear. It will only appear for a few seconds. IF you are installing on a Serial ATA drive with a VT8237/R South Bridge, you will need to watch out for this option and Press F6. You then need to follow the instructions for installing the driver, found in this article. If you are installing the operating system on a VT8237/R South Bridge with a Parallel ATA drive, or any other VIA South Bridge, then this step is not needed.

For the VT8251 you do not need to install the RAID driver by pressing F6 unless you are setting up the hard drives in RAID mode. If the Serial ATA drive is set to standard IDE mode in BIOS, no driver is needed prior to installing WindowsNotes about partitions: The only reason why you would not delete a partition or why you would set up partitions is:

1) if you want to have a system runnings two or more operating systems OR

2) you are reinstalling on a system that was partitioned when Windows was first installed so that one partition has the operating system and one partition is where data is stored ... and you wish to retain this OR

3) You wish to have one partition with the operating system and one partition where data is stored

A partition can be thought of like a little wall (not literally) that is put in the hard drive to separate sections. Each section is assigned a drive letter, C: D: E: etc. A Windows XP installation partition should be around 20GB. If you have a 100GB drive for example you could set up two partitions - one of 20GB where you would install Windows and one of 80GB, which by default would be assigned to be drive E: where you save data. The benefit of using partitions in this way is that if you need to reinstall the operating system you can format and install the smaller Windows partition only, keeping Partition2 untouched. If you only have one hard drive and no way to back up your files then this can be an attractive option.

On that same 100GB drive, if you did not use any partitions, you would install Windows on unpartitioned space. You would still have just as much storage space on the unpartitioned C: drive as if you partitioned the drive. If you have a reliable way to back up your data files, like a secondary hard drive, then my advice would be not to use any partitions. Other people swear by partitioning however. It all comes down to personal choice.

I have therefore provded two sets of instructions in this guide - installing on unparitioned space (the easiest option) and partitioning. If you install on a 20GB partition you then have to set up the other partition within Windows. If you are not interested in partitioning your drive just follow the instructions on the next page and then ignore pages 6 and 7.

Unpartitioned space.
These instructions show you how to delete any existing partitions and install on an unpartitioned space. This is the least complicated option. For advice on partitioning, read over the previous page.



Before installing Windows the existing partitions need to be deleted. In the screen shot above, the top partition is highlighted. To delete it press D. On most PCs there will be only one partition as in the screenshot on the right.



After pressing D to delete, Windows will ask that you confirm this choice with a warning that by deleting the partition any operating system already installed on the hard drive will loose this installation. Press ENTER to confirm.

You will then be given the information to review again, of what partition and what size you are choosing to delete. Press L to confirm for the second time.

You will then be returned to the list of partitions and you will notice that in the screen shot above, Partition 1 has gone and in it's place is unpartitioned space of the same size that the partition used to be. If there are still more partitions as per this example, use the arrow key to move the highlight down to Partition2 and go through the same process to delete it.

Having deleted all partitions the list now shows one Unpartitioned space. Press ENTER to Setup Windows on the Unpartitioned space
Creating a new partition

In this example, Windows is installed on unpartitioned space and you want to create a new partition of 20GB for the Windows install and leave the rest for data storage as a separate partition, assigned a drive letter. In this example the hard drive total size is 120GB.



In this shot you can see the whole drive as unpartitioned space. Press C to create a partition.



You will be asked to enter the size for the partition. No less than 20GB is recommended for WinXP. This has been entered as 20000 MB in the right screenshot.



After hitting enter you will be taken back to the list of partitions which will now show a new raw 20GB partition (as above). With that partition highlighted, hit ENTER to setup Windows on that partition. After you have formatted the drive and finished installing Windows (explained on page 8) you need to then format the remaining unpartitioned space and assign it a drive letter from within Windows. Instructions for doing this are on the following page.

In this second example, the hard drive already has a partition where Windows is installed and another partition. With the 20GB partition highlighted, hit ENTER to install Windows on that partition. The other partition will be left untouched. In the example in the screenshot above, the smaller Windows partition is 20GB and the other partition where data has been stored is 95MB.
If you have chosen to partition your hard drive you have probably followed the instructions on the previous page to install Windows on a 20GB partition. The remaining unpartitioned space needs to be formatted and assigned a drive letter.

Start > Control Panel

Double click Administrative Tools
Double click Computer Management
In menu on the left click on Disk Management. In the bottom right you can see drive C: of 19.53GB (20GB), NFTS (formatted using NTFS file system), Healthy (no known problems), System (indicating that an operating system is installed there). There is also another 92.25GB of unallocated space. Right click on this and choose New Partition.
A partition Wizard will start.

Select Primary Parition.

Choose the size for the partition. Unless you want more than two partitions for your drive (the one where Windows is installed and this one) use the maximum which will be entered by default.

Assign the new partition a drive letter. By default this will be E.

Format the drive. If you chose NTFS for the other partition (my recommendation) then choose NTFS again. Never take the quick option. Do it once and do it properly.

the information about the options you just chose will be made available for review. Click next...
.. and the new drive path will be formatted. This can take some time.

Once the formatting is complete the Computer Management window will show a new volume E:, healthy, formatted with NTFS.

If you look under My Computer you can also now see two drives, C: where Windows is installed and E: which is a partition of the same drive. In the future, if your installation of Windows becomes unstable and you need to reinstall, you could transfer any data you want to keep to drive E: and format and reinstall Windows on Partition1 of 20GB in size whilst leaving the larger partition untouched. Just remember that this is not a failsafe way to protect your data. Any files you care about need to be backed up on a secondary hard drive or by another method.
