My parent's computer has been having massive problems. It's crashing randomly with the blue screen of death (sometimes even right after booting up) and I haven't been able to find the root cause. The usual blue screen error is "memory management" with WhoCrashed saying it was caused by ntoskrnle.exe though it sometimes comes up with other errors and causes. I should also note that it often gives file errors such as corrupted file transfers and downloads and failed program updates. Here are the things I've done to try and fix this:

- Run memtest many times with multiple passes, a couple times testing each stick individually. Passed with no errors every time
- Double checked the timings were correct for the memory modules
- Sent the motherboard back to Gigabyte to be replaced
- Run hard drive tests. All of them so far have passed. I've been trying to do an extended test with the data lifeguard diagnostic but so far the computer has crashed both times during the test.

These are the things off the top of my head that I've done. I may have done a couple others but I can't think of them at the moment. I've been monitoring the cpu temperature to see if it's an overheating problem but so far neither of the cores have gotten higher than 38 degrees celcius.

Here's the specs of the computer:
Vista 64-bit
Gigabyte EP45-UD3R motherboard
Intel Core 2 Duo E7400 @ 2.80GHz
8GB memory (4x G Skill 2GB DDR2 1066 PC2-8500)
ATI Radeon HD 4670 512MB
Western Digital Caviar Black 500GB 7200RPM SATA
OCZ StealthXStream OCZ700SXS 700W

When building this I don't recall seeing any incompatibility information with the hardware. So my question is does anyone know what might be the culprit here?

PS. While typing this I realized that System Information for Windows was incorrectly detecting the memory as DDR2 800. Could the memory be at fault after all or did SIW just misidentify the part?

To really test your RAM, try running computer for a day, or two, on 1 RAM stick at a time.

This could be caused by a corrupt ntoskrnle.exe file. If you have the installation CD for the operating system you can do a repair installation to resolve this. A repair installation will not affect you data.

Boot the computer from the XP CD. You may need to change boot order in the BIOS so that the CD-ROM is the first device in the boot order.

When you see the "Welcome To Setup" screen, you will see the options below

This portion of the Setup program prepares Microsoft
Windows XP to run on your computer:

To setup Windows XP now, press ENTER.

To repair a Windows XP installation using Recovery Console, press R.

To quit Setup without installing Windows XP, press F3.

Press Enter to start the Windows Setup.

To setup Windows XP now and Repair Install , press ENTER.
You do not want to choose "To repair a Windows XP installation using the Recovery Console, press R.

Accept the License Agreement and Windows will search for existing Windows installations.

Select the XP installation you want to repair from the list and press R to start the repair. If Repair isn't one of the option end the installation, this will mean that you will need to do a fresh installation of XP.

The repair will copy the necessary files to the hard drive and reboot, the repair installation will continue after the reboot.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
