So I was just gaming on my custom pc that I've had for about 2years. Then my pc turns off and decides to restart. It gets to the motherboard splash screen then a black screen with a blinking _ bar on the top left hand side. Now it just stays on that screen. I'm thinking it might be the hard drive but any other suggestions. The fans all run and light are all on. Please advise

Ok guys I took my pc to one of my local pc shops. They ran a diagnostic and found nothing wrong with my hardware... They told me it might need a full OS wipe and reinstall or it could be the motherboard. I ran a system restore from my windows cd and it restored the OS. But then i restarted the pc to fully enable the system restore the exact same thing happened. It loads the up to the point right before the OS system. Black screen and blicking _ bar on the top right hand side. So before i buy a new mother board any suggestions?

Ok i bought a new motherboard. Installed it successfully and still have the same problem... It starts up, all fans working, and all lights working. Gets past the motherboard screen into a black screen then just restarts. and does the same cycle over and over again. The really weird thing is that when it restarts its just the motherboard i think. The fans all keep running and so does the components. It just reloads the bios and mb settings. really am sick of this problem. any help please
