Hi, from 2 days ago my PC crashes and I get BSOD, can some1 analyze my minidumps?

I have a AMD Athlon 4000+ San Diego in a shuttle SN25P with nforce4
2Gb GSkill DDR 3200 2,5 3 3 6
Seagate SATA2 250GB
HIS X1900XT 512MB

Thanks.

I can't read the minidump files (no have the MS software), but have you recently added the X1900X or anything else lately?
Typical BSOD causes:
Bad RAM
corrupt driver (any new software or upgrades to existing?)
over worked PSU (not enough total watts and amps on the 12 Volts rail)
temperature problems. (dirty CPU HSF and other case fans)
dieing HDD.
dieing video card.

Some suggestions:
Remove and clean the copper fingers with an eraser both the RAM and video card. Insert one then the other RAM sticks.
Clean with compressed air any and all dust bunnies.

Also read the links in my sig below for further ideas.
Others here will be along to read your minidump files.

Cheers.

This PC is working fine from the begining, the last week I installed the 6.6 catalyst, now I've decided to uninstall the 6.6, run driver cleaner pro and I've installed the 6.5, let's see how it works, the next hours.

I don't have temperatuer problems, the video card doesn't pass above 70Cº in full load, and CPU doesn't surpass 50Cº.

Thanks kirock, I'll check the links.

Hi, another minidump but without BSOD.

Another minidump with BSOD.

I've analysed the minidumps with the microsoft tool and these are the results.
Can someone help me?

Thanks.

I have Ati tool 0.25 Beta 14 installed with Ati Catalyst 6.5? could it be a problem?
No OC in video card.
