anayman_k7 wroteFrom the symptoms you mentioned it is most likely to be a dead motherboard, it is hard to find a similar used one in good condition these days, found a new one at pcandparts but a bit expensive
Gigabyte GA-X79-UP4 (rev. 1.1)(DDR3) (LGA2011) Link $299.00
Macrotronics also has some boards at 350# and 500$, yep, crazy prices
yeah im trying to avoid such solution :P.
the cpu was heavily loaded almost all of the time, im thinking maybe the problem in the cpu (it pasts POST check.) since it was overheating a lot , and the problem exaggerated progressively.
