I have a Dell tower case PC running win XP. I recently switched it on and the power lamp comes on and there is a beep 6 times from a sounder on the motherboard and that's it. I get no busy lights or anything on the monitor. The power supply and processor fans are running and as far as i can tell all power supplies are healthy. I tried Dell but would'nt even start a diagnosis without a payment up front. Has anybody any ideas.
Have you tried another keyboard? If your BIOS is AMI, then I would expect the problem to be as per Forum Editor's suggestion - keyboard controller chip on the mobo, which is why I said try another keyboard.
Looks like a trip to your local PC repairer is needed.
as well as removing the battery there is normally a jumper on the motherboard which has to be moved from bridging pins 1 and 2 for normal operation to pins 2 and 3 to clear the cmos. Once done put the jumper back on pins 1 and 2. You move the jumper when the pc is disconnected from the mains supply.
