Ok, in the last month, I have had to go though 3 different motherboards, 2 Asus and one Gigabyte. I'm not entirely sure what the problem really is, but here is the entire story 1st : The first motherboard I had survived for around 3 months, then died one day, computer crashed, had to do a hard reset, and it never again booted after that, no post, no bios, nothing. Just a blank screen. It was a ASUS M4A785T-M 785G Socket AM3 ordered from Ebuyer.com 2nd: The replacement for this board as i sent it back to Ebuyer, was a Gigabyte GA-880GM-UD2H 880G Socket AM3 board, and this was faulty upon the day of arrival, i never thought i could be that unlucky, and I was sure that it was the motherboard that was faulty, as opposed to another of my components, due to me trying the other parts on another cpu, all of the RAM sticks seem to be working and I assume that if the power supply was faulty, I wouldn't get all the fans and power button to function correctly. 3rd: Today I bought a Asus M4A88TD-V EVO/USB3, AMD 880G from YOYOTECH on tottenham court road. They assured me that none of the models were faulty. Low and behold, I get home and try the board, and no POST'ing, once again. My system consists of: AMD Phenom II x2 555 dual-core 4gb Corsair 1333 ram (4x2) OCZ Xstream 500W Modular PSU Palit SONIC Platinum 1gb GDDR5 GPU Can anyone tell me what else this might be other than a faulty motherboard, because I don't understand how unlucky I can be to have 3 motherboards fail in just under a month :S Any help would be much appreciated.
