Hi
Not sure what happened to my old msg, but can any one help, i have buggered a computer up at the drop in center i go to. The prob is that all was ok and  i restarted the computer the power lights came on but the monitor screen was saying no signal, i restarted again and the same thing. I have tried the monitor on another computer and it works fine. I have also rplaced the graphics card with one that is working and still no luck. The computer beeps once then there is a pause and it beeps AGIN after a few seconds and this comtinues.

Cheers  First check cable is attached via the desktop/tower/to the monitor you may have KICKED it ??......and you have the graphics card .........properly seating........check with the drop in centre.........it support to check it..out.....consult them first..........as it NOT  your pc to WORRY about?/things happen.........~fate~try to reseat the memory, you can also try going into the bios and load bios defaults.Silly question but how can i reset the memory   reseat the memory..... take the sticks out and put them back in.... thats more than likely your problem....... if u reseat the RAM and still have no luck, you need to run a memory TEST software that you can GET from the net, and boot from that disc, let it run and it will tell you if there are errors in your memory, and if your stick is bad....  More than likely this is a memory problem.....
