computer is on but not booting up....

[Wils]

To anyone that can help me...
I tried installing more ram in my computer. for some reason, after i put everything back together, my computer turns on but it makes this fast ticking sound coming from the cd-rom. after the sound, i can hear the hard-drive spin. after the hard drive spins, the same sound from the cd-rom comes on again... then everything stops. the monitor is blank as well.

OK, the first thing to do is take out the new memory and reseat it in the slots, making sure it's in correctly and tightly. Use a flashlight to get a good look to be sure the memory is completely seated in the slot. If you still can't boot, take out the new memory and put your old memory back in. Does it boot then? If so, check your manual to be sure the new memory type and configuration are compatible with your motherboard. If your computer boots with the old memory, it's also possible the new memory is bad.

Hope this helps! http://www.PCGuide.com/ubb/smile.gif
