|It is one of the strange things that in order to flash the BIOS, you need a working BIOS to do it with. The only other way to do it is to take the BIOS chip out and flash it in a stand alone EPROM programmer. Not something you average user would have access to. The BIOS chip is a Read Only Memory chip that very rarely goes wrong. You have to do something really stupid to damage it.|
The BIOS is the least likely culprit. You only start thinking about the BIOS when all other avenues have been exhausted which includes, video card, memory, power supply, hard disk and even the motherboard itself, but not the BIOS.
You need to approach the problem in a logical fashion. Does anything happen? Do any lights light up? Can you hear the hard disk starting up?. If there are no lights at all it would point towards a failed power supply, but not the BIOS.
