Test power supply?
I have an eMachine T2642 that won't startup at all.
Was working before move.
Is the power supply the first thing to check?
The machine has a 20 pin connector and I have a multimeter.
Don't know how to check to see if that's the problem.

Buy one of those. That will save you alot of headaches when it comes to testing what works and doesn't in a PSU.
Did you check the switch on the back of the PSU? Make sure its in the ON position and set to 110V. Look for any scorch patterns on the connector and on the board. Check the wall plug (or powerstrip, or UPS if your friend has one) to make sure you're even getting anything to it. Check all internal connections as well.

Of e-Machines and power supplies, I have seen two T2825 units go dead, one I have right now. On the first one I tested it with a good CPU, memory and PSU, and tested it's CPU and memory in another computer, the known good CPU and memory didn't work in it, and it's CPU and memory worked fine in the other computer so I called the motherboard fried. I ordered a new motherboard for it, and it booted right up everything was working fine. Then after about two or three hours that motherboard abruptly went dead, so I RMAed the motherboard and bought it a new PSU, it has been working fine ever since.
On this other one, I am thinking it is the same problem since it is virtually the same symptoms, so I intend to replace both the mobo and PSU at the first round.

Some emachines models are known for having power supply issues, that end up frying the motherboard. Check the 5 volt rail on the power supply, if it's high, replace the power supply - you will probably have to replace the motherboard also.

I bought a PSU tester which shows no power.
I tried another PSU and plugged into the mobo and HD. The only thing I got is that sometimes the heatsink fan came on for a couple of seconds.
Does that tell us anything new?

Replace the motherboard and power supply.

Don't take this snotty like;
I have an eMachine ...
I used to try and compete with that price point, but fully 60%-70% of the products were DOA. To get an RMA number from someone took a minimum two weeks.
The Engrish was adorable
The supplier's warranty department laughed at me one day trying to RMA some fans from some brand new VID cards I ordered. The fans worked great on the table, turn them upside down in the case and they screeched.
Haven't bought from them since.
