booting up problem

[leptar]

when you boot the computer get into bios by pressing the F2 button... stay in it for about 5 minutes.. that should be long enough to rule out the monitor... DO NOT GO INTO ANY OF THE SETTINGS...

If that goes ok shut down the computer and monitor and reseat the video card if the machine has one, if not then reseat the system memory... use a little caution when reseating any cards or memory.. no force should be needed... if so then you are doing something wrong...

Just remember which slots you took the memory out of and which direction they went and you will be ok...

EDIT:
Should also note that when you do reseat the system memory do so 1 slot at a time if the computer has more then 1 memory dimm...
For instance:
Computer has 512 megs of ram made up of 2 sticks of 256, install back 1 stick at a time then reboot the computer to rule out bad memory... ESD is an electronic nightmare and can affect a component down the road as far as several years...
