Reading a lot of messages regarding this issue, didn't get much of a conclusive answer (and most were from 2005/2006) I got a brand new set up, loaded up XP on it, installed everything & NVIDIA drivers, everything worked fine... 2 - 3 weeks later I would wake up and the computer had rebooted over night, All event logs look similar to this: Error code 10000050, parameter1 fffffff8, parameter2 00000001, parameter3 806036c2, parameter4 00000000. I had over 10 of these at one point, sometimes differnent parameters. I even tried reviewing minidumps etc.. but lets face it, I dont know what I'm doing. I know one minidump pointed to http.sys ( I believe) So I dont have time to really fiddle around with this, so i just dealt w/ the reboots (appeared to only happen throughout the night anyways never while i was actually working on something) but like a disease, it started happening more and more frequently to the point where I'd come home and the screen would be blank, i would do a hard reboot and nothing would come up. cold reboot nothing. reseated ram, nothing, cleared cmos, nothing, reseated cpu, bingo worked again... When I got into system I ran 4 prime 95s (one for each core) etc.., system passed all ram tests for 2 days straight. I didn't get it, next day the computer rebooted again 2 days later same deal, 1 days later, reseating the cpu didnt' work, but reseating the RAM did. To the point where I couldn't even boot into windows any more. each reboot generating another minidump and another ERROR code w/ a very similar read to the one posted above (the one posted above is just the most recent) So i reinstalled windows xp figuring that could fix something, computer was fine for 2 weeks, started happening again, but more frantic this time. This is the point where I said screw it (and this is where the story gets interesting) I Figured w/ all the reseating my mobo must be screwed (considering i was reseating different components) I just went out and bought a new motherboard, ASUS P5KC, installed everyting windows etc.. NVIDIA drivers kept telling me I wasn't getting enough power to my Video card, (My powersupply is a 950 watt, but only 20 amps over the 12v rail) I thought this was madness, I have a friend w/ the same video card and old mohter board (abit ip35-e) even his powersupply was getting the same message, and their computer is stable. I figured just drop another 200 and buy another power supply and I could be out the boat, but instead my friend suggested setting the RAM timings w/ my other mother board (one thing i didn't try), I said fine. I return the ASUS, reinstall the ABIT, set up BIOS correctly, (timed everything out) reinstalled windows etc... Everything is fine for 2 weeks and yesterday the computer started rebooting. I said okay screw this i'm asking for help before I buy anything else. Before I left to work this morning I saw the Blue Screen: IRQL_NOT_LESS_OR_EQUAL I got the event log starting with: Error code 10000050, parameter1 fffffff8, parameter2 00000001, parameter3 806036c2, parameter4 00000000. (can get longer info / minidumps if need be) Do i need to buy ram? A new power supply? a new mobo? anybody?
