My daughter's PC has completely died. When she called me to look at the problem there was nothing on the monitor and all the lights on the case were on (CD and CDRW drives, floppy, HDD activity light, etc). The mobo power light was on so there was powet going to it. Also, all the fans, including the CPU fan were running. The only way to shutdown was to hold the power button for 5 seconds. The PC would not POST when the power button was pressed. No beeps, etc. I checked the HDD and it was spinning and running. I swapped it out with a good HDD but still nothing. I let the PC run for while and checked the heatsink. It was still cold. I also cleared the CMOS but still the same problem. I also took out the RAM to see if I get any beeps when I started it, but still nothing. I'm suspecting the CPU is gone? I don't have any other spare parts to swap out. Is there any reason to suspect the PS, RAM, or MOBO? Hss anyone experienced anything like this before that could save me some $$ and aggravation? Any suggestions would be appreciated.

Here's the setup:

AMD 1700+ 1.4 AthlonXP
Crucial RAM
ASUS NForce A7N266-VM AA
Radeon 9100
Antec SX630II case with Antec PS
