I have assembled my PC about one and half year back. It is AMD Athlon Based Computer with A7n8X Dlx motherboard, 512 MB Ram, Two dists (One SATA 80 GB one IDE 8 GB), running on XP. For Past few days, I am facing this problem On switchin on the computer, it powers on, i.e., indicator lights are on, the fan moves but there is no effect on any of the peripheral, i.e, key board, mouse, monitor...so basically nothing happens. It appears as if BIOS itself is not loading. I was facing this problem for last two months but for many days, everything used to work if i kept the PC box switched on for 10-15 minutes and re-switched again. But for last 15 days, nothing happens simply. Can anybody explain to me ..whats going on and what should I do now. Regards, B S Bora PS: I have already changed the mothrboard battery. No improvement.
