I have an old dell dimension 8100. My 256mb memory stick went through washing machine. I put the memory stick in the dell, and it froze. Did a manual shutdown and tried to boot up. comp will turn on and make a couple of sounds (hd, cd-rom) for a couple of seconds, but that's it. no picture, no nothing. all the lights are coming on and i know the cd-rom and hd are working. any help?
