BleepingComputer.com: Constant, Annoying BSOD's

Hi guys,

I'm looking for help with a major, long running, annoying problem I have.

My computer BSOD's, and a lot.

Main problem I have is the dreaded IRQ not or less equal errors, PFN list corrupt, and the most recent one (that i do have error codes for) is Page fault in non paged area.

codes for this : 0x00000050 (0xFFF2099C, 0x0000001) in win32k.sys.

I can get a variety of these BSOD's, and at any time. It's highly frustrating, but it seems more prevelent when the system is under load - (running a game, Winamp, shoutcast, email, blah blah.) it crashes approx every 30 minutes.

I've changed quite a few parts to see if it helped fix the problem, but that's obviously not worked - (changed the CPU, memory twice, HDD's). to no avail.

Ive got an Nvidia 9800gtx, with the latest driver (v186) and an ASUS P5-NT deluxe mobo, with a Q9550 running on it, with 4gb OCZ RAM.

If i could get advice on how to post the minidumps for more info, to make this more useful, please help! (i cant find these symbol things.)

Thanks,
Rich
