    [​IMG]I have a PC that is a few years old that I use for general web browsing and media playing. Im using Windows XP and various Linux distros.

    A couple of weeks ago my PC would not display anything. I could see it was booting up(hard disc activity/keyboard working) but the screen was just black. I immediately removed the graphics card and connected to the onboard graphics and everything worked- albeit with low performance due to the limitations of the onboard graphics(SiS 761). I bought a new graphics card and put it in only to be greeted with a black screen again.

    So I am now stuck trying to work out if its my PCI-E slot thats gone bad or if it maybe the PSU on its way out. I have ran speedfan and noticed that my voltages dont look right(not that I really understand much about voltages). I just wondered if anyone can suggest a plan of attack as I dont have access to a multimeter and am not sure what my voltages should read anyway. I have attached an image of my speedfan results and just wanted confirmation that my PSU is the likely souce of my problems

    Many thanks in advance

    The 1st thing to try is to jump a known good power supply to the motherboard and see if the problem continues.
