Computer works' something seriously wrong

Every component in the computer tower works fine, all fans are running. When I turn on the monitor it displays the "F8 for bios" blah blah blah, and then it disappears for a split second. If I'm quick enough I can hit F8 and it'll enter the bios, but then a second later the screen goes blank again. I've gently cleaned the CMOS and the RAM but nothing is working. Any help would be greatly appreciated!

  1. Try disconnecting the HDD/SSD (leave only DVD drive) and see if still the same.
  2. Whats the specs bud
  3. Disconnected the HDD, same issue.
    6670
    It's an AMD FX-4100 with a Radeon HD 6670 with a Gigabyte motherboard
  4. 8 gigs of ram
  5. Alright so I've messed with it a bit. Went to RadioShack and bought some thermal compound and re-seated my heatsink on both my processor and graphics card, that wasn't the problem though. When I first start the computer, it displays the main boot screen for a second then disappears, but if I turn the monitor off, then turn it back on again it's still going through the boot process, I just have to keep turning it on and off to see everything and log into my account. But, when I connect the PC to my HD TV via HDMI, it displays with no problem. I've also tried using the blue cord from the computer I'm using right now as well as this monitor I'm using, and it still did the same exact thing, so it's not the cord or the monitor that's the issue. This is so confusing. Any thoughts?
  6. I'm almost ready to get on my knees and beg for help, any insight on this would be greatly appreciated!

    Are you using the same output port from the motherboard/graphics card?
