Yesterday my PC first froze for no appearent reason, I shut it down and when I restarted it again it didn't who any input on the monitor, so I opened the PC up and just blew some dust from the GPU and restarted it, this time it worked. Some hours after it froze again so I shut it down and this time I left it like that for some hours, when booting it again it worked and I started some research about my problem: in the Windows system log I found this "the service KMSELDI service terminated unexpectedly" and googled a bit about it, people suggested to take a memtest, so I did, I booted the PC with the USB and it started testing, but it froze after 3 hours and 0 errors.

I decided not to do the memtest anymore and rebooted on windows, but no signal for the monitor, so again off to blow some dust, worked again. I researched a bit more and decided to reset the bios, so I did, but after resetting it and attempting to reboot the monitor didn't work again. So I tried again opening the PC up and "blowing away some dust" but it doesn't work, nothing displayed on the monitor, tried waiting some time, but after a couple of attempts it doesn't seem to work.

Any good advice on how to get my rig up and running?

By the way, the freezing consists in a still image on the screen and the sounds goes silent.
Also when the monitor isn't receiving any signal the fans and all seem to work.

my specs are:
CPU: AMD FX 6300
GPU: GTX 660
Motherboard: Asrock 970 Extreme3 R2.0
PSU: be quiet! Pure Power L8-400W
RAM: DDR3 Ballistix Tactical PC3-14900 1866MHz 8GB (2x4GB)
OS: Win8.1
