Windows 7: BSOD, usually playing games, other times somewhat random

BSOD, usually playing games, other times somewhat random

Hello out there.
First of all, thanks for taking the time to read this, and help me if you can. I have been getting BSOD's for a while, and combined with it not affecting critical things (like schoolwork) and my course load (don't take 7 engineering classes in one semester, btw :P ), I just kinda let it go.
I'm in a bit of a lull at school, and I just found these forums again, so here goes.

Usually when I get BSODs, they're either "IRQL not less or equal" or "Page fault in non-paged area". Tonight I got "Bad pool header". Attached are the results from the grab tool; Looking at it, you apparently have an abundance of crash reports to peruse.

Last January (2012) I replaced the video card and ram, and the BSODs started around May 2012 or so. I've run memtest86 on the ram sticks and found no faults, and I can't find any sort of software that tests your video card in a similar manner.

Thanks again for your help, and let me know if there's any other info I can provide.

The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.
The internal pool links must be walked to figure out a possible cause of
the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Arg1: 0000000000000003, the pool freelist is corrupt.
Arg2: fffff8a01f4084a0, the pool entry being checked.
Arg3: fffff8a01f4084a0, the read back flink freelist value (should be the same as 2).
Arg4: 11dfc2ef7f7eb2cc, the read back blink freelist value (should be the same as 2).

I'm working on all of that stuff tonight. Should I post results when I'm done, or wait and see if another BSOD happens, then post?

BSOD at seemingly random times. Often when web browsing/playing games.
Hi, I'm new to the forums as a poster, but often find solutions here (thank you). I've been having issues with my computer for a while now, it crashes at unpredictable times. I believe the crashes started about the same time I installed my current video card. Any advice would be much appreciated.
