Diagnose me!

This is the timeline of issues I've had to date, I'm really hoping one of you could define what the problem is (I've got my own theory but I want someone else to confirm it!)

First computer BSOD at vista loading screen

I open the pc, tamper with RAM and then the computer won't switch on (monitor doesn't display, but fans and lights work)

I replace graphics card, nothing.

I play with different combinations of RAM, nothing.

I dig out an old PC and put my PSU and GPU from the broken pc in the old pc.

Runs ok but then crashes when playing games (when under stress perhaps?)

So I swap my graphics cards on my frankenstien rig and I still get the same problem.

The crash isn't a BSOD, it's a proper freeze including sound.

I'm thinking that perhaps the entire problem could be caused by the PSU? At least, that's what I'm hoping.

I would say RAM, have you ran a memtest?
If you have 2 sticks try using one stick at a time.

It is possible its the PSU, but before you splash out on a new one Id check the memory.

Well they're completely different, cause my broken rig is on an intel chipset and my second rig is AMD, they both use completely different CPUs/chipsets/RAM.

So unless both RAM are busted?

Ahh re read your original post, I see what you're saying about the old machine now. Well it is still possible it could be both the RAM sticks but is looking more likely to be PSU as thats the common element throughout.

It was the PSU! (Just incase anyone has similar symptoms)

How do you do Memtest?
How do you test RAM?
