What hardware part is problematic

[Texas]

I get BSOD quite often.

I have:
-install new OS on a second hard drive
-purchased new RAM
-no server that is onboard, so it should not pose problems

As I see it, it's just the motherboard or graphics card may be problem with?

When your computer crashes, I can sometimes not boot it again. I can boot if I get framework out, turn on / off and then put them in again and turn on.

Is there anyone who can help me?

Do you have one or two sticks of RAM?
You can test with one?

I originally had 2, one had errors during mem test, to be sure, I have just purchased a new stick and put in.

Is there someone who can tell me whether getting errors in memtest, may be due to anything other than RAM? I have bought 2 new RAM blocks, and I get red marks on both .. (I test with one of time)

Have you tampered with the settings in the BIOS (OverClocked)?
If not, try 'underclock'.
There could also be a BIOS update from the motherboard manufacturer.

Errors in memtest can result from anything other than error in RAM.
Defect in the CPU and motherboard maybe, I have also seen errors in memtest.

Thanks for the replies!

Yes, it was what I felt with my perhaps unclear wording of errors in memtest was anything other than error in RAM.

Now I have bought new motherboard, think it was the fault thing...
