PSU is junk. Do you have a Known to be good, Compatible PSU, you can borrow for a test unit? Isn't supposed to fire up when you plug it in. Also makes me think there is a weak voltage power rail. Post back in a Comment.

Motherboard turns on but computer can not se almost everthing


Hello there!
Hopefully, I'll be able to help you troubleshoot your problem..
I "poked around" for a spec-sheet on your motherboard:
http://www.legendmicro.com/store/2940_MSI-MS-6380E-010-KT3-Ultra-Socket-A-Socket-462-for-AMD-Athlon-XPDuron-Processor.lmsp

As you're probably aware, this is (in computer years) an antique, but still workable, assuming all cables are in good shape, and tightly connected. -- Again assuming all the cables are good and properly connected, the FIRST THING to try is to replace the bios battery, as it is quite an old motherboard.. considering the age, it is very likely that the battery (if original to the board) is dead, and unable to hold a charge. Motherboard batteries are cheap, easy to find and fairly universal. Try picking up a couple at your local electronics store / dept.. bring the battery along with you for reference.

After you've changed out the battery, make sure you do a bios reset on the board. Find the jumper on the motherboard (mobo for short). with the board properly connected to a power supply, and all needed computer components, take note of what position the jumper is in. With the board / computer being powered down, and the power supply (PSU for short) being unplugged from the wall, move the jumper to the opposite position. Wait about 10-15 seconds. Plug the PSU back in. Wait another 10-15 seconds. Unplug the PSU again, and put the jumper back into its original position.

Then plug the PSU back in, and try to power up the computer. If the problem still exists, unplug the PSU. Ensure that the RAM "sticks" AND the CPU are properly seated in their respective slots / socket.

Then again plug the PSU power cord back in. Try to power up the computer. Assuming that the mobo hasn't failed due to its old age, the computer SHOULD correctly "fire up", and you should be good to go. Feel free to contact me with any further questions!

My computer wont start up. The power supply light flashes green when plugged in then red. But still nothing , can someone please help?


Try a Power Supply Unit (PSU) Reset: Unplug the electrical cable from the wall and the PSU (Back of Computer)
Move the red voltage selector to the opposite position it is in and then slide it back. If you live in the USA 120Vac to 220Vac back to 120Vac
After you have done this you can plug the power cable back into the PSU. Connect the power cable to the wall power. If the PSU is still serviceable it will no longer be blinking.

Compaq FS7600 Computer not turning on


what tower? model, the monitor has nothing to do with power and dead fans in the tower.
'Sounds, (and silent to) means the PLUS in the PC is dead.
all things can be repaired, that is what technicians do.
here is the chain of events, ! to get noise (fans)
power in the wall 120vac , usa
power to the PSU,
the power button goes to the MOBO, and standby power is there
now and pushing said button the MOBO commands the PSU on
if the PSU is happy (PWROK) thinks PSU IS safe the PSU tells the PC its ok, and power stays up.
and fans run.

so my guess bad PSU, its easy to test with anyf $10 voltmeter,
ask.

tower PSU, 101

I have not tried to fix the computer as this is far beyond my abilities. I called a repairman and he said to unplug the unit from the wall and then plug it back in. Did that but nothing happened.


Is the computer completely dead no lights nothing?
If it is
1 check the power lead is plugged into the back.
2 Check the power lead fuse.
3 Check the power lead in another device to establish if it's working.
4 Check your wall socket with another device.
Can you here a humming sound when you switch on i.e. the PSU starting up.
If power is being supplied to the unit and you cannot here the PSU starting up it has to be the PSU in the computer and it will need replacing.

My computer wont turn on


take out the psu completely from the cpu/tower, plug in the power cord,if there is a switch on the psu turn it on, next locate the main power connector (24pin) and find green wire,take a piece of wire and insert it into the green wire connector,next touch the other end of the wire to the psu outer case or a black wire on the main connector,if all is well the psu will turn on,if you have a dc voltage tester check the voltages on the red and black wires on molex connector...5vdc,yellow and black...12vdc.if ok look at the main board and inspect the capacitors to see if they are swollen, if ok
replace psu and disconnect hdd,cd/dvd,floppy ect from main board only leave memory,processor and video, power on if ok shut off and reconnect hdd, power on, if ok shutoff and connect floppy, if ok power off and connect cd/dvd drive.during this testing you will know what is bad.let me know how it turns out.email; arjoon.ken@gmail.com

Comp not firing up


Something may be shorting out the board. Try taking the motherboard out and turning it on without the case. Just put the motherboard and power supply on a non-static surface. A box works well. Then use a flathead screw driver to temporary "jump" the 2 power switch pins for the front panel connection (as you wont be turning it on while inside the case).

If that doesnt work, then replace power supply. You could also take one out of another working computer just to test.

My Ibm t49 the display shuts off as soon i as i boot up help


There are several possibilities within two categories:

SOFTWARE (you are using MS, so this is more likely)
HARDWARE these symptoms can be caused by bad battery and/or bad PSU (AC Power Supply Unit)

Software: You may have a virus, or may have damaged the NT kernel, or some critical software components by installing cheap games or bad SW. Read the recovery instructions on your XP CD to boot and run recovery and/or utilities that might repair the laptop OS. If you have no CD, try booting and hitting F6 key after BIOS screen... then explore the options there. Next, try booting and hitting F8 key after BIOS screen... then explore the options there.

If there are no problems repaired or evident in software, you should remove the battery, plug in the PSU and try booting. If all goes well, your battery is probably bad. If NOTHING happens, then your PSU is definitely bad (or the PSU cable/jack/connection to your computer is bad)

Conversely, remove the PSU and boot only with the battery. If it boots up (or goes farther than it did before) then the battery may be low/damaged BECAUSE the PSU is bad. If your laptop does not even open/get at least to BIOS screen, then the battery is dead. Try recharging overnight with laptop off but plugged into AC. If it is the same in the morning, replace the battery.

Both the battery and PSU can be checked with a VTVM, to compare voltage/output levels, with the ratings on the labels
