hi am helping a friend fix hes pc but i can's boot it up. whe i turn it on i can only see the front leds on but nothing else gets power,the cpu fan is not moving and the cdrom drive does not open. the power supply on this pc has a square 4 pin connector and the regular 20 pin that connect to the mother board. http://techreport.com/r.x/tyan-tige... I just tried to use my power supply but mine does not have the square 4pin connector but is has one that has P7 printed on in and i dont know what this is for. I have disconnected the cdrom drive,hd,floppy disk and i also remove the ram stick but still nothing works. my friends power supply model is... Condegen model:200x1 Please if anyone can help let me know.

The square 4-pin plug supplies power to the CPU...the system won't boot without it. http://www.emachines.com/support/pr...

Thanks. also i forgot to tell that the pc fist began to reboot for no reason and i also like to know if anyone know of any other emachine that does this I just remember that an other friend some time ago asked me to fix his pc and it was a eMachine as well.

well it may sound like a power problem. but when you say the cpu fan is not spinning. do test the power supply. you can get a tester design for power supply tester you can get that at any computer store. maybe even radio shack do ask for it. here is a link to get an idea what it looks like. http://www.phoronix.com/scan.php?pa... you may have to copy this link and paste it in the addres bar. other wise it may get burn out the cpu. Have a Great Day ;-D

It does sound like you have a failed power supply on your hands. When you purchase a new one, don't be frugile about the cost and $50 ought to get you a fairly decent one.

I've used several eMachines in the past, and the one consistancy I've noticed with all of them is that they all suffered from power supply failures long before any of my other PC's (Sony and Dell desktops). Rebooting and random shut-downs are one of the first signs of either overheating, or, a dying power supply. ~ Sarah C. ~~~~~~~ eMachines H2602 1.9ghz Athlon XP 2600+ 80gb HDD Primary 40gb HDD Secondary Windows XP Pro w/ SP2 512mb DDR PC2700

I tested the Power Supply with an older pc with windows 98 and i had no problem. Thanks everyone it must be the processor or the mother board but i guess my friend has to spend some money at the repair shop. Thank you.
