Hello, after 2 years of having no problems at all with my computer couple of days ago on my computer (windows 7) i had a BSOD so it restarted itself with vertical white lines all over the boot up menu then back to normal after that page and would get stuck at a black screen after windows loading page. So i thought it was the graphics card so i took it out and reset my CMOS and started the computer using my on board graphics card and the vertical lines were no longer showing which made me think it was the graphics card. I tried to install Windows 7 again which went fine till the windows loading page where it showed a black screen with a mouse cursor on it so i didnt know what to do. I found an old Windows XP SP2 cd i had lying around and installed it just to see if it would work and installed it and loaded fine. I have been using windows xp for a couple of days till suddenly today i got a BSOD again and i wanted to find out what exactly the problem was before i could replace them. Please help Could someone have a look at my .dmp files to see if it says anything about what the problem could be coz i have no idea what it all means. Also how would i go about testing my motherboard, harddrive, ram, processor any of these are faulty. Thanks in Advance.
