Dell Dimension E520
Win XP SP3
Nvidia 8600GT
4GB Ram
Antec 500W PSU

This computer has never had any issues, all drivers always updated and gets cleaned regularly. I turned this computer on one morning and was presented with a loud fan and nothing on the monitor. The lights on the front panel act "normally". The loud fan sound just sounds like the fan is in overdrive or something. I shut the computer down using the power button, waited a few minutes and tried again. Same thing. I then completely cleaned the inside of the case, removed and cleaned everything! Put it all back together and tried again. Same thing, except no loud fan sound, just a "black" monitor. I did notice that they CPU fan spins slowly when it's trying to boot. My first thought was the PSU. I replaced it with a spare known (assumed) good PSU and get the same results. Also verified the monitor/cables/etc were good. Any ideas?

Would a bad CPU fan cause a "no boot" situation?
Fried motherboard?
Video card?
Hard Drive failure?

Sorry so long. Thanks for any help!!
