i cannot boot my computer, i have disconeccted everything but de video card, memory. So no hard disk or cd, when i turn ON the computer the light turns on and the fan and i think i can hear the processor running, but my monitor doesnt shows a thing, actually suddenly, by making no change i the Dell screen appeared and i could enter the cmos-bios, and everything was fine, but it only happened for about 4 times, and then back again to the initial problem, ive also taken out the cmos battery for around 6 minutes, and then back again, i dont know what can it be, PLEASE HELP!!!

well with dell's "award winning" customer service they could probably help you.. maybe the memory has gone bad? Dying power supply? Not sure...

i dont think its the memory, as far as i know, when there are memory problems the internal speaker beeps, (once or twice or something), any other recommendetions, thanks a lot, i NEED HELP!!

i don't think that ALWAYS happens.. i was just giving you shots in the dark.. hopefully someone else knows

dell is instructed not to help you with some things

besides

opening the case on a dell voids the warranty

oh... yea.. but he doesn't have to tell them that
