A few months ago, I bought a Asus M3A76-CM mobo to replace the last one that I accidentally blew up (oops!). I rebuilt the computer but it wouldn't POST or POSTed and crashed during or shortly after booting. So I took the graphics card out (Sapphire HD4850) and used the on board graphics and works resonably well (apart from it almost always crashes within the first few mins of being on, but fine afterwards). I re-fitted the card yesterday after the computer had been on all day and no problems (playing MW2 for over an hour) but when I switched it on this morning, same problems as before! So I left the card out and the PC on all day today, refitted the card, flashed the BIOS and it was working. Switched the PC off for half an hour and problems back again! It's like it doesn't like booting from cold (like an old Ford Fiesta! lol). Can anyone point me in the right direction? Mobo faulty? Graphics card faulty? PSU (Tagen 480w) faulty??
