I turn my computer on and after a short time (maybe 30-60 seconds) my monitor goes to saying there is no video connected. I can barely enter the bios/setup menu before i lose the video. It shows me the boot screen so the video does start to work but then it just stops. All i have changed is I tried to put in a new hard drive today (SATA 3.0) and after i did the computer booted just fine but then I tried to burn a disk and sometime while the "windows disc image burner" was running my computer froze and when i tried to boot it back up the problem started. I have unhooked everything inside my computer except the video card the ram the processor and the fans, but it still only shows video for that short period of time. Does anybody have any idea what this problem is? Is it a broken video card? Or a broken motherboard? What else can i try to locate exactly what is causing me the problem?
Also I have a 700 watt PSU so I doubt that it isn't getting enough power and my motherboard has no onboard video card.
