hello ive been trying to trouble shoot whats happening here my pc had been randomly restarting on its own (not the blue screen of death) when i plugged in a headset or anything else for that matter and now has stopped working completely,well it powers on but i get no video most times i unhooked the hard drive and was able to get into bios but as soon as i plugged my headset in ( as a test) it started back into a reset loop . any ideas as to where i can go next troubleshooting this issue?im drawing blanks at this time.

its not the headset because the same problem happened with another headset, i broke it down yesterday to a smaller power supply without the video card worked fine all day until about 40 minutes ago, started loosing the hard drive, then picking it up briefly and loosing it again, thinking maybe sata controller or cable might be my problem.
