That's a great comment.

Back years ago I was a navy technician. 1964, in fact. When I first finished school and reported aboard ship the chief gave me a nickle and a flashlight, and told me I was going to be first on site on every single call - day or night.
The nickle was used to open cabinet doors and the flashlight was to be used to LOOK! Then, after I had observed symptoms and evidence I could call an experienced technician to come help me fix the problem. I was amazed at how often I did not make that call. Just fixed it myself and went back to bed.

Maybe I'll get that lucky with this computer...

No luck. Re-seated the RAM, looked carefully at what I could see, checked out his monitor by hooking it up to my system.

Decided to replace the full Monty - power supply (what th' heck.. $20), Motherboard (ASRock 97M), and went for the processor (Intel G1860) as well.
Total cost $200.

It's a pain to remember how I did this all 3 years ago, but there is no hope for the BIL figuring it out for himself. Sometimes ya just gotta help out when you can.

There is very little chance that you need to replace all 3. I've been building and repairing computers for two decades, and only had one which needed the full rebuild - and that was because a liquid cooling unit sprung a leak and fried everything.

It could be something as simple as a bad monitor cable.

Power supply could be bad. Just because it fires up doesn't mean that it is sending the correct voltage on every leg. I actually had one that showed the same symptoms as yours, and the PSU was dropping voltage on the lines that went to the video card. Yours is onboard, but it could be the same issue. To check a power supply, you need a multimeter and a list of voltages for each leg. These should be on the PSU label, if not check the manufacturer's website.

The chance of your processor being bad is almost nil. Even if the heatsink fan is totally occluded, they don't fry - especially from what us gamer types would call light use. The PC will shut itself down before the processor gets hot enough to be damaged.

Trying to diagnose the computer without actually having it hooked up in a working environment (monitor, keyboard, mouse) is a pointless exercise.

If you or he have $200 to throw at the problem, it's all good. However, I'd be trying to figure out exactly what the problem is and buying only what I needed to fix it.

I hear ya.
Wish I was a bit better at troubleshooting this kind of thing, but I'm not.

Monitor and cable are OK; I hooked them up to my computer and they worked fine.

BIL isn't paying me to do this and $200 is not too much to ask of him. I only want to do the job once, since it's kind of a pain.
A couple of years ago he asked me to fix a lawn mower for his son. When I got the thing all tuned up and humming, he just put it in his own garage! Said his son didn't really need it yet........
So I ain't real fired up about spending a lot of time on his computer. But it is what it is - his wife is my wife's best friend...

Just out of curiosity, how would you detect an inoperative processor? If I had an oscilloscope I think I may be able to see if it's clocking at the right rate of 2.7 Ghz........... is that how you would do it?
