Hi all
Intel celeron 10g hard drive(very small almost full) compaq evo compact desktop.
My wife uses this for game play etc.
It had 1 512m & 1 256 card in it & worked ok.
I removed the 256 card & put a second 512 in.
When i boot up i just get 3 beeps all of the same length & the monitor light goes green & then back to orange & the screen says no signal.
We bought the tower cheap about 12 months ago at 256mb so i put another 512 in it which made a great improvement.
Just wondering why when i try to upgrade further this is happening.
If i remove the second 512 & put the 256 back in it works fine.
Thanks in advance for any help & keep up the good work.

What happens if you put the stick that causes the beep in by itself? If it beeps and no boot you have a bad stick. If it boots fine, then the 2 512 sticks aren't compatible...

I'm glad you figured it out! And no, you're not stupid...RAM is a tricky beast to deal with
