when ur starting the tower and it light are on and ur fan there is no problem with the power supply, i think that u rily need a new motherboard because ur board will not boot on start up..

I don't see how removing the battery would help but tried for the same problem and it did in fact do nothing.
The fan races but the system never makes it to the Bios and never displays anything on the monitor. I suspect a chip is fried on the MoBo.

Maxum52, please post the solution if you found one.

It sounds like a dead motherboard. Try removing the CMOS(BIOS) battery and replacing it. Then try removing and replacing the CPU as well. If you get the same result then you might be looking at replacing the motherboard.

Instead of sleep mode, tyr hibernate. It is generally faster except the whole computer shuts down. When you power back up, you're exactly where you were. Mine takes about 30 seconds.
