Hello, I would like some help with my desktop, I am running widows 8 pro on a gaming computer only problem is it keeps freezing on start-up, safe-mode pretty much on all boot up sequences (i can get into windows at times but usally fails when desktop is activated/opened from metro IU)

spec's:
Processor: AMD FX-8350 8-core Processor 64x Liquid-cooled (not overclocked or turbo active)
Ram: 16gb g skill sniper series
Motherboard: UD-7 gigabit motherboard
Graphics card: X2 ASUS HD7770-2GD5 Radeon HD 7770 GHz Edition 2GB 128-bit GDDR5 PCI Express 3.0 x16 HDCP
HDD: 1T seagate hard drive
O.S: Windows 8 x64 / Linux Ubuntu x64 (Duel Boot)

I have tested my ram using memtest and memtest+ for hours never failed any tests
I have run HDD tests not failed (Pratically Purfect score)
I have run bench-marking tests and other tests on graphics and processor even played games on it

any clues to what could be wrong?
