Cpu problem?

I recently replaced my motherboard (identical replacement). At first it booted up perfectly. I rebooted a few times and then let it sit turned off overnight. The next day I did a couple more reboots, with no problem. I left it on and ran an errand, and when I returned there was nothing on my monitor. I turned it off and tried to reboot and got nothing but long beeps for the post and nothing else. All the fans are spinning, but nothing else is happening. Can you advise please?

Have you reset the CMOS?

If you don't know how, most motherboards have a reset button located near (usually) the CMOS battery. If there is no button, you can always unplug the computer from the wall, pop out the CMOS battery and let it sit for about 15 seconds.

I would try to post with just one stick of RAM installed. If the system posts, manually set the RAM speed/timings/voltage to the manufacturers specs. You could then try to boot with both sticks of RAM installed.

Thanks, I did this with no change. I appreciate your trying to help.

+1 to shortstuff

Try booting with only the HD, CPU, video card, and 1 stick of RAM. If it doesn't work, rotate each stick through each slot. Everything else can be unplugged.

Have you looked in the manual for your mobo and see what long beep codes represent (long continous beep usually means memory error. Steady long beeps may mean power supply. This differs with BIOs, however and they are not universal)?

Just saw Outlander's post. Use his link. +1

Thanks - no luck - I'm still searching around though.

Did you ever check what that beep code means for your Motherboard?
August 12, 2009 11:15:10 PM

Yes, and I can't find the answer. I have Award Bios and either I'm not looking in the right place, or they simply aren't willing to share that information. The system is almost 8 years old, but still. If I had a POST

I'm sorry, I hit a wrong key and my reply was sent before I finished. I don't have a POST card so I can't determine what the problem is. The beeps are continuing long beeps that keep on until I turn the system off.

did you read the link I gave you which lists the beep codes for all the common BIOS?

August 13, 2009 1:59:06 PM

Yes, unfortunately, they are not very forthcoming about the Award Bios. I'm still searching. I've emailed the maker of the mobo as well.
Thanks.

I would like to thank all of you for your suggestions. None of them worked, but just so you know, I switched out the mobo and put everything back on my old one and it seems to be working fine for now. The only thing I can come up with is that the "new" mobo was defective in some way.

I do appreciate all of your help.
