Hardware Issues

So here is what I started with just in case it matters:

i5-750
Gigabyte P55-UD3R
Radeon 4890
4GB G.Skill DDR3
550w Corsair PSU
Crappy low profile heatsink
Seagate 500gb HD


My computer has gone through a variety of issues over the last month so I am hoping maybe someone will have an idea that I haven't.

A few ago I upgraded my heatsink to an H60 and added a Kingston SSD to my setup that was working normally. For about a week the additions worked normally, and then upon installing Acrobat Reader and attempting to open a PDF my computer began to get random blue screens.

I thought I had possibly had an issue installing my OS so I decided to try and reformat the SSD. However, my computer began to hard lock about halfway through the Windows installation.

Having had similar issues in the past I thought that I might have a bad stick of ram. I pulled one of my sticks and Windows installed normally.

The computer worked normally for about a week and I thought I had solved the problem but then after playing Starcraft II for about 2 hours, without any temperature issues, the computer just shut itself down. No blue screen, no errors anything, just turned off.

I tried to start running diagnostics and got through a couple before the computer would even hard lock while in Ultimate Boot CD. Both Sticks of RAM passed MEMTEST and I cleared the CMOS before the computer began to turn off roughly two seconds after turning it on.

I now thought it seemed like a PSU. I swapped in a working PSU and received the same results.

I then began to think that I might have a short or something so I took the MOBO and all out of the case and started to try and boot with just a CPU, RAM, and a video card. After figuring out that the 800d and my MOBO doesn't have a speaker, I got a speaker plugged in and got the post code of 1 long, 1 short. According to the Interwebs, that meant there was a problem with the MOBO, so I ordered a new MOBO.

Upon receiving the new MOBO(MSI P55-CD53) I plugged in the essentials and did not get any kind post code. Rather confused I plugged in the video card and got no feed from the video card to the monitor.

I have swapped between 2 previously working video cards, while also trying 2 different previously working PSUs.

So now my computer seems to turn on normally and then sends no feed to the video card. Having gone through all this other stuff I am kind of at a loss. My last guess is a CPU, which might prompt a complete upgrade, or I will just RMA it to Intel and hope for the best.

Any ideas or help would be greatly appreciated.
 
At first I thought maybe the SSD was giving issues as they are still new tech. Computers do not boot without any CPU in the socket, so that maybe dead now. Do you still have the old mobo laying around? If so I would give that a go and see if you can still make it boot at least. That may show an issue with the new mobo if it does.
 
Memtest does not always identify bad RAM. It could take days of loops to find it. I'm guessing you put the other stick back in after the install, and began having problems again, yes?
