Serious crashing problems please help

[frank2000]

Hi guys or wizards I am in need of serious help here. My PC is custom built, so components are some new and some old ish. I will list the specs below for references.

AMD Quad 9500
Corsair 4GB DDR2 800
Gigabyte MA78LM-S2H AM2+ / AM3
Samsung Spinpoint 1TB Hardrive
Sapphire ATI Readeon HD 5770
Thermaltake Tough Power 1000W PSW
LG DVD/RW - Standard

OS: Windows 7 Ultimate

Here is the problem
It's been fine ever since. However recently I starting to experience blue screens of death. But thats not it, sometimes my monitor turns pitch black, the PC is still running the fans are still on. Other time the screen just spazs out and turns itself off then to pitch black screen.

I attempted to update all drivers (except bios) because I do not know how to.
The latest graphics driver etc etc. And it is still happening, the oldest component I have in there is the PSW which was about 3 years ago almost. At this stage I do not know which component is causing this failure. CPU? Motherboard? PSW? Windows 7 corrupted?

Any help would be much appreciated as my head is about to explode about this matter

Thank you very much

It would help to know the error listed on the blue screen. Or you can go into the event viewer to find out whats going on.

OK I will try to take a snap shot next time if I get to see the BSOD again. Thank you
