New Motherboard, PC wont start

Drakarn · July 16th, 2004, 11:48 PM

Heres my problem. I just bought a new motherboard, a pentium 4 processor and a memory stick. I installed the processor and the memory in the motherboard and plugged the motherboard into my computer. But when I try to turn on my pc the green light on the motherboard comes up and the fan starts spinning. But the pc itself wont start. It wont start the hard drives and wont turn on the cd-roms. If u unplug the cdroms from the motherboard they actually start but that doesnt help me any. If any one knows what the problem could be. Please reply. Btw I never installed any motherboards before and dont know much about it except what it tells you in the manual.

Welcome to Techimo!

First, I would check that the "Clear BIOS" jumper is set correctly. I've got one that was shipped to me with it set in the clear position.

What kind of board is it?

If it has Nvidea chipset, unplug it for 30 seconds to reset the bios if you find the jumper is set correctly.

Its a P4P800 SE ASUS motherboard. and to tell you the truth I have no idea what are the clear bios.

Oh and I bought this at the store. The guy actually plugged it into a computer at the store and it worked fine, i think, then he just unplugged and put it in the box as is.

When the guy at the store connected it all, did he use all of the compoments that you purchased?

If so, try reseating everything,,, but before you do the CPU, just reseat the ram and make sure that all connections are in there correct spot, ie. power, fans etc.

Some times it is just the ram that is not in properly.

One last thing.. When the guy at th store tested it all di he disassemble the CPU and fan? as it may need some reaplication of thermal compound.

Do you have the four pin ATX connector hooked up?

And if so, do you have another power supply to try?

Then try one stick of ram, 1 Hdd, and the video card, mouse, keyboard and see if she boots up. Just the minimum needed to run. Tell us if it at least POSTS...

Right near the battery you will see a three pin jumper. Your manual will tell you which pins are correct. However if the guy in the store ran it and it worked, then the settings are ok.
