Hi,
Hard Drive specs and other things are not an issue right now. My main focus is getting to my BIOS. I have an ASUS P4C800-E m-board, an Intel 478-pin 3-GHz processor, and tons of cooling in my case. My components brand's are: Maxtor(HD), ASUS(m-board, cd-rw, DVD-rom), Kingston RAM, and everything else is Thermaltake(case, power supply, cpu fan). I have an ATI 128MB PCI card in there. It's brand new, just bought it from the store about a 2 months ago, I put it into my temporary gameing machine (dell with windows 98)(not pretty but works) and it works fine. I also had a Nvidia 32MB card (also PCI) in the new build, but I do not get video with either of them. I tried taking out the battery for 24 hours, nothing. I understand that it is possible that the Bios is set for AGP only, however, I would like to avoid spending money for an AGP 8x card. Does anyone have advice?

if you have changed from your gf card to your ati card or vice versa without un-installiing your old card then it could be as simple as dissconnecting the power supply and then removing the CMOS battery for 30secs-1min and then replace the battery and reboot

The thing is there is no os installed on it or anything. I just did first boot, and nothing. (I tried several times of course)

I would also like to add that I hear everything else working, hard drives turning, normal computer ticking noises as if eveything is fine. But no video, I will try Imp's advice, but I do not think it is a power problem.

If you have onboard video
take eveything off of board(all pci agp cards whatever)
remove all the memory and cpu

somewhere on board is a jumper for the cmos leaving the battery in
jumper the reset for 40 secs or so
replace the cpu and as little amount of memory as possible
if you don't have a onboard video add this now
do not attach your hdd's yet power up system see if you get video
sometimes the cpu is not set right in socket sometimes the memory is bad from box lastly I have had to reboot without the video then shutdwn and add video and reboot can be frustrating

Discontinue thread

Ok I'll try it. There is no onboard video by the way though.But for now everyone please discontinue this thread for a while, I have just gotten some additional visible hardware problems that I have to work out (new parts). Also I have been thinking lately about IRQ settings. So I am going to study my M-board and book for a while to see if that could be a potential problem. So Discontinue this thread

Before you do so, check the pins on your keyboard and mouse PS/2 plugs. Friend of mine had a similar problem the other day. His PC would boot and run perfectly at my place, using my equipment, but at home nothing went!. Turned out to be a bent pin in the keyboard plug.

New Update

Turns out I am having a BIOS problem. I get no beep codes and no video at all. When I pulled out my RAM I should have heard something.

I have a very similar setup. I have the same board and processor at least. I too am having a bios problem. I get no beeps or anything. I rma'd the mobo and they sent it back and said there were no problems with it. Never gonna buy an asus board again.

You've plugged the additional 4-pin power plug (for processor power) into the motherboard, correct?
