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
