Question about Acer Veriton 6900 PC Desktop

1 Answer

Acer Veriton 6900 Desktop says no signal and the screen turns off. The towers power light stays on but the fan isn't running.

The screen works. The tower seems to be having problems. The power light will not shut off. It seems to need rebooting. Unplugging doesn't work either.

Change the power supply and restart your pc. This will happen when the power supply has gone bad. It sends power to low voltage items but not the needed voltage to power the system on.

Good Luck

If your computer boots up fine, it should be be the bios battery. Flashing with the wrong bios usually makes your computer completely unusable (showing only a black screen), so I think this is not the case.
You will need a CR 2032 lithium 'button'-battery. If you havent got one lying around, try a local radioshack, photo supplies shop or watch shop.
Replacing the battery is pretty simple: remove all the computer cables, open up your computer (touch a metal part of the casing first to rid yourself of any static), locate and replace the battery on the motherboard. Put it all back together and voilà.
(the first time you boot up again, your pc will give another checksum error, but you should be able to set the time. On the next bootup, there should be no 'checksum error' message, and the time should be correct)
You can find some extra info on here:

Should an ACER 5900 veriton, processor cooling fan, vary in speed ?

Yes all computer fans will vary their speed in order to conserve power. They will speed up when the processor is being used as it generates more heat and needs to be cooled more but if the tower is inactive the fan will slow as it does not need as much cooling.

Before your computer running fine, you just remove the fan and heat sink, and fix properly.

1) Check your VGA cable both of side fix properly
2) Check your Monitor power button is switch on.
3) Remove your RAM and fix again.

Acer veriton m460 won't turn on fan runs that's it

Power supply failure. Replace it. Get 50+ more watts than the original. Power supplies are inexpensive and can be replaced without affecting your operating system or programs.
BTW: Many "failed" power supplies still can deliver enough power to spin fans and turn on the lights.
I recommend:
