If the supply was the previous problem, the motherboard may be destroyed as well. Try it with just the motherboard, PC speaker, processor/cooler and power supply. If there are beeps, then the motherboard is ok and it may be the memory.

The computer wont start up, i can see a green light on the motherboard and nothing else. even the power button wont show up led light.


This can be a power supply problem or a motherboard problem.
One or the other has probably gone bad and must be replaced, if this is what happened.
Start by disconnecting all things from the motherboard except the CPU and memory.
If the system starts, then you've ruled out the power supply, CPU, motherboard, and memory.
If not, remove the memory and see if it tries to start. If so, then the problem is the memory.
If not, then it's definitely the power supply, CPU, or motherboard.

How can you tell if the mb is burned out or if its actually the power supply?


Very good question.

I faced the same issue not long ago. I opted to try the cheaper route of replacing the power supply and hoping that that was the problem. Luckily, I got lucky and that was the issue.

What was strange was that the system would appear to turn-on just fine, but specific parts of the system would not function like the hard drives would not spin-up. After replacing the power supply, the system booted normally like nothing had happened.

If you have a multimeter, you might try measuring the voltage coming from each power connector coming from the power supply, but be careful while you do this.

Thanks for using FixYa

Turn on the computer nothing happen then smell burning from the power supply! turned off right away.


That power supply is probably dead. try your motherboard witha known-to-be-good power supply to determine if your system has survived. IN my experience the failrate for antec sp450 watt psu is close to 40% over 4 years (300 pc:s at university), so there is a high probability that your psu is unrecoverable.

At start up power lights and fan are on but nothing else happens. i have tried starting up with supplied recovery disk in tray.


sounds like faulty memory try using only 1 memory stick at a time to find the bad 1. If youve only got 1 in there replace it.

When I push button to turn on, the light flashes orange. Nothing happens, no fan, nothing. It worked fine yesterday.


This usually means a failed power supply and/or failed system board. No way to know further without swapping parts. Power supply is cheaper to replace .

PSU hangs the system: can't turn on; turns of in 30 min


either the power supply needs replaced or there is a short on the board...

pull the mb and guts of the system out of the chassis

connect the power supply with one cpu and one stick of memory for testing.. no add-in cards installed

then test the power capabilities..

if the system works out of the chassis.. ( alot of work to do ...understood )then there is short to the chassis of the from the motherboard

i really think the power supply is the issue though

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.

Continue this pulling out pci cards one at a time until you find out what the problem might be.
Try different keyboards and mice too.

Power supply


I think your problem is not with the power supply, its the hdd or memory thats causing the problem. try to check the cables, and re insert the memory then start up your pc again.

Acer Aspire 3000 Power Issues


In this case myself assume that your acer do a problem in the memory, try remove and clean the memory.

1. boot your acer without the memory. hear beep? if yes,
Only memory has a problem, if no, then;

examine the mainboard of your acer.

If you can hear a beep then fix back the memory and start the system.

if this not solve the problem, replace the memory.

In case that it hard for you to open the laptop let the repairman do it for you so that all your problem will be examine.
