Cpu not powering press on button lights flash fans turn for a sec

If you are not getting the computer to start up but you are getting the fans to whir for a moment and the keyboard lights to flash, then that means that you probably have a bad motherboard. If you had a bad power supply, most likely none of these secondary indicators would be present. I would advise taking the computer to a local computer repair shop and having a professional investigate the problem. More than likely, he will be able to tell you the cause of your problem in short order.

Hey
Do you overlock your pc? If yes there is a possibility it's your CPU that is dead.
It also could mean you have a bad motherboard or bad memory stick.

Check your memori first just un

your hard drive might be fried so I'd advice you to take it to a pc shop

When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

try to turn off the laptop and remove the battery and the power cable. Then press and hold the power button for 5 secs. Then reinsert the power cable and battery on to your laptop.. Turn on the laptop, and if the cpu fan cycles on and off, that means there is problem with the fan and also the power supply of your laptop. Call Acer to replace the power supply to stabilize your laptop's electricity...

Did you flash the main board ??

1.) remove battery
2.) press and hold the power button for 10 - 30 seconds
3.) replace battery.
4.) when the system boots it will say press XX (e.g F2) to load defaults and continue ,, press that key.

It could also be the power button is stuck!.

find were it connects to the main boad and unplug it
bridge the 2 pins it jacks into to turn the computer on. if it works u will need to replace that button or the case.

This can be a faulty power supply or a damaged mother board. here's how you can confirm.

When pressing the power button, inspect the cooling fan that is located on the back of the power unit where the power cord plugs in. if the fan starts then stops immediately, this will confirm a damaged power supply.

Now, if the fan continues to operate but, the CPU doesn't start to power up and load the OS, thsi will confirm a mother board issue. replace the mother board in this case.

Mine wouldn't stay on - press the power button and the lights would flash for a sec, then it would go dead. I removed the fan/heatsink assembly, the CPU, and the memory (2 SODIMMs). I then resocketed the CPU, replaced the fan/heatsink assembly, being careful to tighten the assembly evenly and gradually onto the CPU. I'm not sure why, but it works now!

hiya

it seem as as tho ur cpu is over heating...... take the case off and have a look to see if the cpu fan is turning if not theres your problem......

if it is turning it cud be the fact that the cpu isnt getting enuff power or too much...

is the cpu overclocked at all....

hmmm.. The Ring of Death.

The 4 rings mean power faliure.
The 3 rings mean the CPU has been melted.
The 2 rings mean there is a CPU overheat error.
The 1 ring means there is an internal error.

Hope this could of helped you.
