If you see this post in the devices section you will notice that i'm a newbie and i didnt see the section for bsod problems. And the reason this post is so long is coz i'm at a university computer and i dont have internet at home...joy... Hey there everyone, so im new to this forum so hey all! After frequent googling for solutions to BSODs and error codes i thought i might as well try a forum to find some answers and seeing as this one helped me with another prob i thought that cpc2004 could help me by looking over my mini.dump files. I've seen you help many a folk with analyzing their mini dumps. If its not too much to ask...and anyone else's help is also welcome may we all POST in peace thanks all. By the way my pc components are as follows E2160 at 1.8Ghz GA-G31M-S2L( bios f7) 4gig muskin ddr2 800 (2*2gig) xfx 9800gt 1 ide 30 gig 1 sata 120 gig 1 sata 500gig 1 dvd-rom, writer 500W Gigabyte psu vista 32 bit Basically what happens is that my pc wont post sometimes. It just starts up all fans spinning but it just stays on black screen. So i open up and take out my g card to reseat it and reseat both ram sticks, turn it back on and it starts up and all is good.Been doing this for months now, thought i'd live with it as i could still play games nicely(COHOF). Lately tho i've been getting regular bsods and non-posts with different code's showing up, like 0x0D1 and 0x0A with USB.Sys Address and others i cant remember. The bsods happen when its just idling on desktop or when i'm watching an avi. I tried my friends alpha dog 8800gt and ran 3dmark 06 and all went fine, but i didnt leave the card in their for too long as he needed back. Tried my 9800gt and ran 3dmark 06 and a bsod occured. So i thought it was my gcard, so i tried my pc with just onboard graphics and it did not bsod at all when idling or watching an avi. Then i tried my old 6600Le g card and it started up fine and idled fine, but once when i paused(relevant?) the avi it bsoded with an 0x7f code: BCCode: 7f BCP1: 00000005 BCP2: 00000000 BCP3: 00000000 BCP4: 00000000 This has happened only once, but with this card in my pc is already more stable as it starts up fine and no regular bsods like with my 9800gt in. Oh and i've tried different nvidia drivers from 178.13 to 181.22 with no luck... And if anyone was wondering i have tested both my ram sticks with memtest86+ 2.1 at least 2 hours in all possible configurations with the ram sticks and it showed no errors. And i've tried with xp and vista with clean installs. BTW no bsods while installing os's...Thanks for the help all Feels good to talk it out with a forum.
