Attempt to install new RAM. Troubles abound.

I built my PC a couple of years ago and recently decided to upgrade the RAM. I ensured the RAM was of the same type as my old RAM before purchase, just larger. Once I installed the new RAM my computer would not boot; power is on nothing on the monitor.

I swapped back to my old RAM, still not working. I reset CMOS with the new RAM in, no luck. I reset CMOS with the old RAM in, no luck.

Later I noticed that my fans weren't running. So I got a new power supply. Now the fans run, lights are on, I even hear the HDD working. Still nothing. Even tried clearing CMOS again with each set of RAM with no luck. I tried using different monitors on different ports in case it was a video card issue.

I am out of ideas and appreciate any help that gets this machine working again.

Specs:
MOBO: PC Chips A13G+
CPU: AMD Athlon 64-bit Dual Core
RAM(old): Corsair DDR2 800MHz 1GB x2 sticks
RAM(new): PNY DDR2 800/667/533MHz 2GB x2 sticks
(if any other specs are needed I'll try to figure them out)

I've seen RAM slots get damaged when they were brittle and swapping memory caused them to break. No guarantee that's the issue, but such would explain your symptoms.

Tried placing only one stick of RAM in the #1 slot only..? If that doesn't work, try a single stick in the #2 slot only..

Hope this helps.

I did as you suggested, Grif. It appears that one of my memory slots is not working. The computer booted (with the new RAM) but only if I leave one particular slot empty. Is there any way to fix this or do I have to get a new MOBO to make full use of my RAM? Also, if replacement is necessary, are there any suggestions as to how best to replace the MOBO while maintaining the data on my HDD?

Thanks for the assistance!

If you're so skilled, then give it a shot. I find such tasks beyond my talent and I simply replace the board.. If you can find the same model motherboard, you should be able to simply swap it in.. If not, then you'll probably need to perform a complete format and reinstall of the hard drive..

Either way, if you can get the computer running, even with one stick of RAM, then make a good backup of your important documents, files, music, etc. Then replace the motherboard and see how it goes. Or...live with lesser RAM..

Hope this helps.

Haha, I started updating my backup as soon as the thing booted. I'll get started hunting for a new MOBO. Thanks for all the help today, Grif.
