Question about E-Machines EMA IMPERIAL GV (845GV) TG3 eMachines (145119) Motherboard
The pc would not power on, no lights or fans, so i tested the power supply with a multimeter and found out it was bad. i purchased a new power supply and put it in, but still nothing worked. i pulled the new power supply and tested it. it was good. so then i plugged up an older power supply to the machine, eventhough it did not have a 4-pin connector, and the fan on the power supply came on and the light on the front panel came on(amber). what am i dealing with here? am i dealing with a bad motherboard? how do i determine this?
Some eMachines computers (like many from Dell) use a non-standard pin out for their power supplies, so if you try a standard ATX power supply it may not function.
However, in my experience it IS likely to be the motherboard. Luckly I have been able to replace quite a few of the eMachines mobos with a standard mATX mobo, since you can probably remove the IO plate. You'd certainly want to replace the power supply when doing so.

One bad or faulty lead connection can cause a computer to continue restarting on a cycle or to shutdown or fail to detect your hard drive
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.
Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty
if its a 40 pin flat ribbon type it will be the first to fail
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty
even something as small as a faulty electrical fan and its lead can cause you problems
computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error
make sure your graphics card is securely seated with no dust built up or in the socket
if you remove your graphics check the socket to make sure its dust free
restart your computer then reinstall it this should activate found new hardware wizard
hope this helps
