PC was working, then crashed, now won't boot.

So, a few months ago in late-December 2014, I bought parts for a PC. I wanted to custom build a PC. I already knew a bit about building and had friends that had previously sucessfully built one, and with help from the internet and friends, I built one. About 3 days after I build it, it crashed one day, and never booted again. Before it crashed, the screen flickered, and lines appeared across the screen. At the time, I really wanted to go on it, so I figured it would be the GPU. I RMA'd it, they did not approve, they said it was working. I then bought some new RAM, same model, still no fix. I then RMA'd my motherboard, they said it was fine. I formatted the hard drive, still no fix. I couldn't be bothered anymore, so I left it sitting there for 6 months. So, 6 months later, today, I had the sudden urge to fix it again. I decided to test the remaining 2 components. The PSU and CPU. I started off with the PSU. I removed it and shorted the green wire (power) to the black wire (ground) so that it could switch on without it being connected to the PC. The voltages were normal, nothing extreme, the fan was spinning, no indication of fault. Although this method wasn't the most accurate, I put the PSU back in and hoped for the best, and you know what? It worked! I installed Windows 7 Professional, I installed the AMD Catalyst Suite, and now came the problem. The problem occurred the same as it did 6 months ago, but in different ways. Last time, it happened when I was playing games. This time, it happened when I tried to set my Windows to Aero mode, transparent bar. I am hoping it will start working again, I'm going to let it cool for a bit now.

Here are my observations:

The northbridge and another thing next to the CPU is getting pretty hot. Normal? I don't know.

My specs? Here:

I'm running Windows 7 Proffesional 64 Bit.

Thanks in advance to anyone who helps. I will try answer any questions to my fullest!

When you say the fan spins, do you mean the case fan, the power supply fan, and/or the CPU fan?

From experience, it sounds like your system is overheating. Make sure all of the fans are plugged in and working.

Every fan is spinning, the CPU fan spins, the GPU fan spins, the PSU fan spins and so does the case fan. All of them are connected. Do you think there is a compatibility issue as I'm thinking of getting rid of the current GPU and getting a Nvidia in place for it. If not, then what else do you think could be the problem? Do you think that the fact that the both the problems have occurred after installing graphics drivers is significant?

That information runs me into a sort of "brick wall." I can not think of any other reason for the issue.

I hope you can find a solution, and I will keep thinking about it.

Alright, so just recently, I found out that for my motherboard to support AM3+ FX CPU's it needs a BIOS update, which I did do before it broke the first time. But after it broke the first time, I did wipe the hard drive. Does this mean that there is no updated BIOS for my motherboard, or once it's updated it's stored elsewhere? If someone could validate or confirm this, that would be great!

Thanks for anyone that helped, I have found out that it is either a faulty GPU or a faulty PCI express slot. I am having to push the GPU down with my hand to get it to boot.

The bios is stored inside of the motherboard, so there shouldn't have been a problem with the bios after it had been updated.

Check the "prongs" in the slot, and on the GPU. If any are bent or broken, you may have found the problem.

I'm guessing by "prongs", you mean the golden bits inside the PCI express slot. If that's the case, then no, it all looks fine and dandy. Same for the graphics card. I think my motherboard might be mis-aligned because when I put the screw in at the back of the case to hold the card in, it pulls the card up a bit. I'm thinking of selling my current graphics card and replacing it with a nvidia equivalent anyway.

Thanks for all the help that you have given me!

You were right about what I meant by "prongs", and no problem, I enjoy helping people with computers.
