here a bit of story i did with my pc desktop. i tried playing with the bios and did the following : i reset the memory speed from 533-667 mhz and when the pc restarted, no display came up. i tried reseating all the components including the cmos battery but it did not give out any display...here's the fun part : i tried to take out the memory and power it in; here's what happened : the fans indicates that they are receiving power and everything moves normally (except that there is no display) but when i reseat the memory, the pc does not power at all...if you guys can help me figure out what the problem, i would be grateful or if someone can tell me how to get to the bios to reset it, THAT WILL BE GREAT..and i promise not to play with the bios again..(i promise, cross my heart and hope to...)

Without this it's very hard to offer any help at all to you.

But basically on some M'Boards in Desktop Computers there is a 3 Pin Header Strip with a Plastic covered Metal Jumper that supplies Power to the CMOS from the Onboard Battery.

You need to find this Header and move the jumper from the 1 2 pin combination that it is set to and change it to the 2 3 to short out the Power to the CMOS and delete the settings in BIOS. After you have done this you need to move the jumper back to the 1 2 pin setting or the system will not power up.

If there is not a 3 Pin Header Strip you need to remove the BIOS Battery and leave it out for about 30 minutes with the Power Lead disconnected.

That should wipe the BIOS with most Hardware unless it is the newest available and then we need to know what you have to give you the right directions.

When you say you reset the memory to 533-667mhz what do you mean?
What is the correct speed of the memory and type?

It's either your BIOS is having trouble using that memory under default settings (Mhz or voltage issue) or you've damaged the memory.
