Have i fried something ???

I attempted to add some memory to my no.2 PC. I replaced a 128mb stick/card with a 256mb stick. It is a K7 mobo with and amd/athlon 1.2 Ghz chip. Previously it had 2 128mb pieces of memory, the 256 piece came from an identical PC that had stopped working.

Any help or suggestios would be gratefully accepted.

 

You haven't actually told us the problem

 

Sorry, the pc doesn't turn on or attempt to boot, there is no sign of life from the hard drive and a blank screen.

I have a spare video card if necessary but i think i have caused a problem when i changed the memory, i have put it back how it was and no life.

 

I've just tried a different hard drive and it booted. There was a message saying CMOS battery low and something about CMOS memory being incorrect, it wasn't on the screen long.

 

Sounds like you've got your problem resolved?

Either way, if you would like to replace the CMOS battery, its small, round, metallic, and on your motherboard. They're usually CR2032s, but you can check on it to be sure. They're cheap to replace (I got one for $5), and it is just a matter of pressing a latch to remove one. They last about 3-5 years, and can cause some weird problems, most notably system instability.

 

Yeah kind of, the working hard drive is infected, but i think i can clean it up ok .

Will the other hard drive be out of action ? I'll check it.

 

I've tried the 256 stick with the drive that works, and nothing happened, no boot. Also when both original 128 sticks were in it only registered 128meg of memory so one is fried perhaps ???

 

Are some of my sticks out of action ??? I only got 128 meg of ram now. I got 3 128 sticks and 1 256 stick and it seems only 1 is working now.

 

I would try taking the ram out, cleaning the contacts with compressed air and/or contact cleaner, and re-inserting them, so that they sit firmly, and the latches snap into place on their own.

Then, try Memtest86+

 

OK, i've got the memtest iso file. When i burn a cd should i instruct the burner to make it a bootable disc ???

 

it sounds like maybe a bad RAM slot, have ou tested the 256mb stick in the other slot?

 

I think the 256 stick is bad, i've got it back to normal with 2 128's working now. Everytime i put the 256 in it wouldnt boot.
