Did you have any power surges or fluctuations recently? If you've tried different RAM combinations, clearing CMOS and the like...then it's possible your board is toast. Have you tried unhooking everything from the board except for PSU, graphics card, CPU, and 1 stick of RAM? Just so its down to the bare basics.
Monitor is working properly. I started the pc with just psu, cpu, graphic card and a stick of ram, but it didn't least boot. The 12v cable which from smps goes into socket located near the inbuilt graphic card and the cpu fan. While starting, the fans start for just 4 seconds. If the 12v cable is removed then the fans operate normally, but the pc never boots. Is it cause of inadequate cooling, that the mobo has failed. - kunal
