i bought a rig on ebay about 3 or 4 months ago. i had to re-insert the graphics card when i bought the rig, it would power on and not give any video signal from the VGA port (after i reinserted the card it worked fine). I occasionally get bsods when i'm using it. the os is windows 7 64bit home premium (the OS came with the rig i haven't reinstalled the OS). see the msinfo for more system info. the bsods are rare - it probably happens once every few weeks (so it's not really bothering me) but today (15/01/2012) it happened twice in one day and now it's gone back to doing it rarely. I just don't know what it could be. I've included a minidump and i've ran msinfo32 and exported the system info. please see the attachments- I am not sure if this is related also skype version 18.104.22.168 is the only version of skype that doesn't crash on this system. every other version of skype just crashes (the system itself doesn't crash just the program). Even the very newest versions of skype crash (straight from skype.com). any other version i try just crashes, i don't know why but i am sure it shouldn't happen. my friend has windows 7 64bit home premium and he doesn't have these skype problems.
