Very weird problem with booting computer

Hello everyone,

It has been around a year that I've been playing on this build:

Case: Thermaltake Armor A60
CPU: AMD Phenom II X4 965 BE running at 3.7GHz
Cooler: Thermaltake Frio (not exactly sure on the specific model)
RAM: CORSAIR VENGEANCE 8GB 1600MHz running at 1333MHz
GPU: XFX AMD R9 270X
PSU: Thermaltake TR-600W
Motherboard: ASUS M4A87TD/USB3

But, these last couple months, booting the computer started to be irritating.

Whenever I press the power button, the motherboard gives out a beep code (1 long, 3 short).
Sometimes it doesn't even want to POST.

I did find a temporary "solution" to my problem : shaking the computer case eventually leads the PC to boot. After that, the computer works just fine. Very weird...

However, I believe that this "technique" will damage my components in the long term. So, what do you people believe is the problem?
 
The only reason shanking would work is if there is a loose connection, otherwise it is just because you waited long enough.

Your motherboard has this manual that came with it, which will actually tell you what those beep codes mean. If you don't have the manual you can download it online. https://www.asus.com/Motherboards/M4A87TDUSB3/HelpDesk_Manual/

I've looked around the motherboard's manual, but it does not mention anything about the beep codes. For the loose connection, what do you believe is loose?
 
Depending on what company makes your Bios (AWARD, Phoenix, AMI, HP) it would either be RAM, Video Card, or possibly keyboard.

Try running 1 stick of memory at a time and see if that makes a difference. Remove and reseat your video card (making sure it is in all the way), also might try a different card if you have one available to you.
 
That beep error code is typically the video card. I would open the computer, not shake it, and look for loose connectors. Particularly how well the video card is seated along with the power cables to it. While you are in there, take it the computer outside and use a can of compressed air to blow out the dust and then check the rest of the connections including that the ram is nicely seated.

I tried with 1 stick of memory but no improvements on booting the computer.
I also reseated the video card to check if this was the problem. It did work for the first try on booting the PC. However, after closing the computer and restarting it an hour later, the problem came back. I have another video card, but since it's broken I can't test it.

I cleaned the computer and went to check for loose connections. I didn't see anything loose, but I reconnected all the cables again to make sure nothing was loose. Nothing changed.

I thought maybe bread boarding the computer could help me find the problem. What do you think?
