PC doesnt post, quite oftenly.

So I have a bit of a problem here. Recently I moved my PC from one room to another in the same appartment. After that I have had some regular issues where my PC wouldn't post at all.

Then I tried to isolate the cause, but still no confirmed cause found, even after a month.

When my PC doesnt post, I just have to unplug the SATA cables and plug them back in, and then my PC will post in the next boot.

Sometimes, playing with the SATA cables doesnt work at all. At those times, if I remove the power cable for my GPU and plug it back in, boom... my PC will post again.

And on rare occasions, both of the above methods dont work, and then I remove the RAM chips and plug them back in, and my PC will post.

If I keep my PC on, then there are no issues, it doesnt restart even when I play graphic intensive games. So it doesnt seem to be a heating problem. But if I ever restart my PC, for updates or other reasons, then it wont boot up and say DVI signal not found. During this time, the fan are all spinning, and the lights on the keyboard and mice lightup as well. And if i shut down my PC, then there is a 50-50 chance that it will post or not. And if my PC doesnt post, then I follow the three steps I mentioned above, and eventually one of them will make my PC to startup again. Also, this has happened once before, that none of the steps above will work, but I just kept my PC off for about an hour, and then when I powered it on, it posted automatically.

So, my problem is that the NO POSTING happens quite alot, and I dont want to keep my PC powered on for no reason. If anyone can help, it will be appreciated.

My Specs:

AMD FX 8350(no OC), MSI 760GM FX motherboard(don't remember the exact model)

ASUS GTX 550TI, Gskill ripjaws 8GB 4x2

Seasonic 500W, Thermalright Venomous X Cooler,

Seagate 1TB Barracuda, NZXT Source 210 Elite Black

PS: I bought my PC in 2011, so would the hardware be starting to die???

PSS: I tend to keep my PC clean, so about every three months I give my PC a blow with a compressed air can.

Try reseating RAM? Offtopic: Nice CPU and GPU combination.

The common denominator here is the motherboard. So that's my first thought about this.

Just for shits and giggles, can you move your computer back to the old room and test to see if the issue persists. It is kinda a longshot, but since it's easy enough to test... It is possible that the new circuit has a different power profile issue that is causing a power variation that is giving the mobo a bad time.
