Alright I've been having problems for some time now and after posting on several boards and getting almost no feedback, I've found this one which looks alot more promising. I built my own computer about a year and a half ago, here are my specs: Windows XP SP2 AMD FX-55 PCI-E ATI X850 XT 2GB Corsair RAM 80GB Maxell HD, 250GB Western Digital HD (No raid) eVga nForce4 Motherboard 420W PSU This is a fresh install, I just reformatted and reinstalled Windows about a week ago. Spyware-free here. I've actually taken out 1g(2 512mb sticks) of the RAM after another board suggested memtest86 and with all 4 sticks in there it listed that I had over 7k errors. I removed the newer RAM that I had just bought and the errors went down to 3.5k. Just out of curiosity I took out the old RAM and ran the test with just the new RAM, errors down to 282. I re-arranged the pattern of the RAM and now the errors are down to 20. They were all on test 7 as well. Not sure exactly what that means. Anyway! The problems I've been having are that I get BSOD's quite often. IRQL_NOT_LESS_OR_EQUAL is the most common one I see. This happens whenever I play games for more than a few minutes, upload music via iTunes, or try to record music via firewire. My computer BSOD's then restarts with the CPU at a very high temp, usualy 65C. So I always turn it off and wait for it to cool down. Idle, the CPU usualy runs around 40C which I believe is normal. So what I'm wondering, is this a RAM problem, overheating problem, PSU problem, driver problem(doubt it), or even something else? I've uploaded a few dumps from different occasions, hopfully someone can take a look at them and let me know what's going on. Thanks!
