How do you check if the CPU is still good?

[Dentilicious]

My sister's Dell 8100 desktop just recently died. I'm thinking it's faulty power supply. In any case, is there a way to check if the CPU is still good, should I even be worried about it?

It happened to a friend before with his athlon and he said his mobo was also gone, but his CPU was fine.

Is there a way to check if the mobo's still good? Seems like Dell's using a proprietary mobo layout and power supply. The power supply pins are different from my Abit TH7II-RAID and the Dell mobo won't work with my other generic brand P4 PSU.

Well, what exactly happens when you try to power on the PC? Does it power up at all, fans & hard drives spin up? Or nothing at all?

If the CPU was dead, the computer would still try to start up. Drives and fans would run. If the Power Supply was dead, nothing at all would happen when you went to power it on.

More on the proprietary connection(it's even one of my bookmarks, it makes me that...well, upset):

The computer doesn't bother turning on at all. It's just straight up dead.

That means it's got a dead power supply. Better contact Dell, so you can pay them 4x what it should cost, if it were a "normal" psu.:disgust:

Becareful. Power it up the MB. Do the fans spin? Do you get the BIOS beeps that it finds the memory, etc. The motherboard, CPU or both might be dead. I had a MB almost melt, but I thought the CPU was OK. Intel said they would replace it ---if I tried it in a working computer. Would you let me stick my crispy CPU in your computer to test it?? I told Intel I tested it, they sent a new one, I bought a new-old MB at justdeals.com for $35 shipped. It still working 2 years later. R
