I DBAN'ed my PC which was working fine. After DBAN I didn't mess with anything inside so technically it should still work. However, when I turn it on a bunch of random colored blocks appear on the monitor and that's it(looks pretty terrible). The monitor is connected via a vdi cable to the GPU. I tried using a vga cable instead but it doesnt pick up a signal for whatever strange reason.I tried pulling out the GPU thinking maybe it was interfering with my Mobo's IGP vga connection but when I disconnect the GPU the PC doesn't turn on (it powers up for a second and then just shuts down). I can't do anything in the BIOS because like I said I cant see anything. I already tried wiping down and reseating the RAM.

I'd say you have a bad video card. Corrupted display, no output to one port, I think that's pretty definitive. A video card that's missing or isn't fully seated will cause a computer to fail to boot.


Yes, Mr. Death... I'll play you a game! But not CHESS !!! BAH... FOOEY! My game is... 
WIFFLEBALL!
