Hi everybody, hope i choose the right forum to post my problem. Recently i bought components for new computer, and i am experiencing a random program closing, sometimes restart right after windows is booted and logoned (not even theme and background is loaded correctly), even memtest sometimes show error. so i was assuming that memory is causing the problem.

First my configuration:
Asus p5kc
2x1g Patriot extreme
E6550 core 2 duo
8800gt
550W LC power supply

What i want to know is, what can cause those problems if memory modules are not corrupted? could it be cpu? or something else?

I also loaded system defaults so no overclocking during this problems.

I tried to raise voltage for memory module and for cpu, nothing better.

I am really desperate now i will be thankful for every info you will give.

Thank you!

It could be a faulty or insufficient power supply also.

Voltage lines seems fine.

Something I have noticed that many overclockers thses days seem to overlook. Even though the new OS's are more stable and are better at recovering themselves....
If you overclock to the point of getting system errors, just setting everything back to normal may not fix your problem.

A bad overclock can result in disk read/write errors to the point that a complete reinstall of the program, and many times even your OS is still needed.

That is what i wanted to ask, if OS can cause problems (sure not directly), but question is if there would be an error in memtest because of that?

Thanks for answers guys!

No, memtest runs on Linux, it's own operating system.

I checken in memtest at boot and as windows, both show error sometimes. Tomorrow i get some rams to test, so will see if they are causing error.
