A couple of weeks ago, my computer suddently crashed (the screen blinked twice, and then the computer shut down).

Upon restarting it, I got no picture and my motherboard made one long and three short beeps.

After trying all sorts of things, I decided to send in my GPU, and I had a replacement sent, but after installing it yesterday, it seemed to work, but it was just hanging at the motherboard splashscreen. I then tried to enter BIOS to see if there was something wrong with the boot settings, but I couldn't enter BIOS. After hitting DEL a few times, the onboard speaker would start making a weird clicking sound every time I hit a key on my keyboard.

After having tried restarting a few times, It went back to doing the same thing as before I installed the new GPU... One long, three short beeps.

EDIT

Motherboard: Gigabyte X79-UD7
CPU: Intel i7-3930k 3.4Ghz
GPU: ASUS Geforce GTX 670
RAM: 16GB Corsair Vengance
Powersupply: Coolermaster Silent Pro Gold 1000W
Harddrive: 1x 1TB Western Digital, 1x 120Gb Corsair

EDIT 2

Right, so now I get a picture, but it hangs at debug code 62... I've done a bit of research and this seems to be a problem with the new sandy bridge architecture... Time to RMA my motherboard..... Thanks for all the suggestions, though! :)

Do you have more then 1 PCI-E 16x slots available for your graphics card? Could be a dodgy PCI-E slot. –  Simkill Mar 11 '13 at 10:09
    
what motherboard? –  Davidenko Mar 11 '13 at 10:20
    
It's a Gigabyte X79-UD7 :) –  Krogs Mar 11 '13 at 10:51
    
According to the manual of your motherboard, your board should have a debug LED. What is it saying? –  Alvin Wong Mar 11 '13 at 10:56
    
Ah yes, sorry, when I had just installed the new GPU, it was booting as uaual, untill the screen where I can choose to enter BIOS (which didn't work) The Debug Display shows code 64, which seems to be a memory issue, but that doesn't explain why my old GPU was broken. –  Krogs Mar 11 '13 at 11:15

have you checked your RAM as well? just in case. if you have more than 1 stick, check the RAM by running one stick at a time.

Edit Based upon your new update to the OP

Possibility 1)

The beep code indicates an issue with the VGA or even Enhanced Graphics Adapter (EGA); and you've said you've changed your GPU. Basically your machine thinks the GPU RAM is bad, or can't detect it correctly (maybe it's not seated properly).

I would test another graphics processor as well (is there one built in on your motherboard?) (if you have a spare/old one).

At this stage though my gut feeling thinks it could be a faulty motherboard.

Possibility 2)

The beep code indicates a conventional memory failure

You need to test just 1 RAM chip at a time, but it may also be the memory location (the slot), all RAM may be corrupted or it's possible it's not seated correctly.

Really...? The OP says 1 long 3 short. Also I don't think every motherboards act the same. –  Alvin Wong Mar 11 '13 at 10:49
    
@AlvinWong Yes, I know it says 1 long and 3 short, and this can indicate either RAM or Video/Video RAM issue. See my updated Beep codes for different BIOS in link in my post. –  Dave Mar 11 '13 at 11:09
