Newly built computer random freezing and freezing on starting windows

[Skytri]

I recently built my first PC three days ago...
Specs:
i7 bloomfield 960 processor
4x4 vengeance ram
crosair hx850 PSU
evga x58 ftw3 mobo
hd 6870 radeon graphics xfx

When I first installed windows it started to work just fine but I soon noticed that it would randomly freeze every 15-30 minutes of use, but not on a particular program or anything. I assumed it was drivers so I installed the latest drivers for my GPU and MOBO and keyboard. It seemed fine again until it started crashing again. I ran a GPU burn test and a CPU burn test it passed both... (I tried runing memtest86+ but it froze at like 12%) Then I tried fixing the registry so I downloaded ccleaner and fixed the registry problems. Freezes continued. I finally decided to re install windows so I did and the problems still continued. I am at a loss of what to do and can't think of anything else.

any advice would be appreciated if not I will bring to a repair shop and have them sort it out.

Hello Skytri and welcome to Seven Forums. My usual disclaimer: I'm not at expert at anything.

I'm wondering if there isn't a RAM problem. Perhaps one of the sticks wasn't seated properly, etc. You could open Resource Monitor > Memory tab and make sure all RAM is being recognized. Make sure Installed = 16384MB and the Available + Cached + Hardware Reserved is the same amount. (You are using 16GB total, correct?)

If Memtest freezes you could try a quick check for a bad RAM module. Install one stick in Slot # 1 (or whichever slot the mobo manual says to use.) Run the computer to test for freezes. Test each of the remaining sticks one at a time. If all 4 sticks work you might want to go through these troubleshooting guides. They are time consuming but many people have been able to isolate their computer problems.
