my mother in law has an Emachine pc desktop and one day out of the blue it just started acting up, i went there to see if i could figure it out and i couldn't see anything and the fans were louder than normal. The lights turn on, i don't recall hearing any beeping when the pc is turned on but i can open the cd drive. i've tried hooking it up to a different monitor and still the same thing, any ideas on how i can fix this problem by myself without having to take it in? thanks!

Reseat the video card...reseat the RAM...check all connections for all devices...that would be my start.

Then, if necessary, I would try a different video card (first) and monitor (second).

Some eMachines motherboards have a history of dying without visible symptoms. At work we'll spend days troubleshooting them, then resort to a format and reinstall - only to find that the problem still exists. I had one customer that nearly lived in our shop for 6 months until we replaced the motherboard.

The "recipe" we generally use is:

Do a malware scan
Visual inspection of the motherboard and components
Test the hard drive with a diagnostic utility
Test the memory with a diagnostic utility
Test the motherboard with a diagnostic utility (Eurosoft - $498 to $861) - THIS IS NOT A COMPLETE TEST OF THE MOTHERBOARD!!!
Repair the MBR and Boot Sector of the hard drive
Run CHKDSK /R on the hard drive
Check the various error reporting tools in Windows to ensure that there's not another problem.
Check for BIOS/Driver updates that may affect this issue.
Backup the data if the customer wants it.
DBAN the hard drive (Darrick's Boot And Nuke)
Install Windows, install updates, then install drivers
Test to see if the problem has gone away.

If that doesn't fix it, then we assume it's the motherboard

Without video you won't be able to do the majority of the tests.
So, you've gotta work on getting the video to work first - then (if it does work) you can run the rest of the tests.
Without video there's just not much that you can do.

I'd start by switching (temporarily) another power supply in.

I think those tend to go pretty easily with eMachines systems.

What's the model number of this system?

The hard drive can be removed and connected to a working system for testing.

The RAM can (possibly) be switched to a known working system for testing.
