Computer keeps overheating


Your power supply has a theoretical Maximum output of 700 watts, but the problem is that the hotter it gets the lower that number becomes... It's obvious your power supply can't handle the power draw or the heat from the Graphics card when taxing it by playing games... Two things you should do:

1. Make sure you have more than just your power supply venting hot air out of your case... Adding a fan or 2 will help take some of the cooling stress off the power supply.

2. Buy a better power supply... Newegg.com is a place I get most of my PSU's. Read their ratings and compare specs. You will notice on that site that your particular model is not rated very high.

When I put my PSU on the ON position, it makes no noise, but when I turn it off, it makes a hissing noise and does the same if I unplug it. It was bought two weeks ago and made noise when I first used it,...


if its only 2 weeks old should and its brand new be under warranty

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

hope this helps and good luck building your first computer

How to power up a compaq 243890-001 power supply without the the motherboard? Its not green to ground


Remove Power Supply
1 . Shut down your computer and unplug the power cord and all cables connected to the system.

2 . Open the computer case and disconnect all power connectors from the motherboard, drives, cards and fans.

3 . Remove the four screws that secure the power supply to the case. These screws are located on the back of the computer case, at each corner of the power supply.

Wire and Start Power Supply
1 . Switch the power supply to the "Off" (sometimes "O") setting.

2 . Insert the end of one wire from a single pole, single throw (SPST) switch into the green wire of the ATX power connector (the largest power supply connector).

3 . Insert the end of the other wire from the SPST switch into the black wire of the ATX power connector. If your power supply has two black wires, connect the SPST to the black wire directly beside the green wire.

4 . Wrap electrical tape around the ATX power connector and wires from the SPST switch to hold them in place. Make sure there is no exposed copper or silver wire from the SPST switch wires.

5 . Turn the SPST switch to the "Off" position, if not already set. Plug the power supply into the wall outlet and switch it to the "On" (sometimes "I")setting.

6 . Connect any other computer components that you wish to operate without the motherboard, such as fans, drives or cards. Turn the SPST to the "On" setting to activate the power supply.


Hope the above information will be helpful to you.
Thanks.

Power supply not working?


To see if power supply works
unplug the psu from the motherboard and drives
then plug the power cord into psu and wall
the fan should come on letting you know that it works.

you can also get a multimeter and check each individual connector on the 20/24 pin connector to motherboard.
check the psu docs for the correct voltages to each pin

If you smelled smoke then chances are that something may have gotten toasted.
remove all expansion cards and try to turn on computer if nothing happens then the motherboard may have gotten toasted.
Check the motherboard and expansion cards along with memory for shorts and burn spots.

Tower problems


You may need to replace the cmos battery, its a cr2032 3v button cell
Make sure all your expansion cards and memory are reseated.
Make sure all cables are reseated.
your power supply could be bad

If that doesn't work try this


Here is my fix for the dell dimension 4400 amber light problem. It works!
replace cmos battery.
then unplug power cord form wall about 5-10 secs.
then plug it back in, wait 5 secs.
If amber light comes on, press and hold power button until it goes out.

(with light out, press and hold power button while amber light comes on and goes off again holding power button 2-3 secs after light goes out.) repeat whats in parenthesis until computer turns on
it should only take about 6, 7 tries.

After the computer boots, you may want to setup cmos or boot into windows.
After you shutdown, unplug power cord for 5-10 secs then plug it back in.
Press and hold the power button, computer should come on.
I found that's the only way to turn on the computer.
If you shutdown and don't unplug power cord the computer may not boot, mine didn't.
Strange I'd say

System is not workin properly


You might try this. Shut down the computer, disconnect power cords, disconnect everything at the back of the computer, mouse, key board, etc. Open the case, ground yourself by touching an unpainted area of the case and remove the power connectors to ALL optic drives and floppy drive if you have one. (Of course do not disconnect the hdd.)
Reconnect mouse, keyboard, etc., and power cords to wall outlet.
See if it will post now. If it does I say you have a faulty power supply.
I was given a computer which was doa. It would not post, after I tried the above routine it posted then booted to windows.
I replaced the psu and now the computer works fine.
Hope this helps!
