I was having the same problem and I just fixed it yesterday. You will never guess what was causing the loud fan noise.... give up? the NVIDIA Quadro Graphics Cards that were in there...... I bought an ATI Radeon 3870 yesterday popped it in, installed the drivers, and now my computer does not sound like an airplane anymore....... this card is amazing and its on newegg now for 80 bucks..... itds GDD4 as well and the games look better than a playstation 3........ this card also improved my overall system performance drastically.....

I figured out how to ghost a Dell Precision 490 with a 32 bit Windows XP Image! Like you I had the same problem where it would constantly reboot after I imaged it with an existing 490 image. The answer is actually very simple. Boot up your Precision 490 and hit F2 to enter the bios. Select Drives and then SATA Operation, change it to "Raid Autodetect / ATA". Reboot the 490 and re image the machine, it will now work!

If you are getting no video at all, then we can use the diagnostic LEDs and the power LED to help determine the failure.
