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.

Motherboard is active but nothing appears on monitor


The problem is with your memory installed try inserting other RAM on your computer or if you have two memory installed try removing the other one and see if it works.

Computers won't turn all the way on


If the cpu were damaged, you would still get something at boot.

Smell your power supply? Do you smell arcing or burning. If so, it may be your power supply. You can get a power supply tester for about $20. The power supply has several different voltages that it supplies. So, the system might seem to be on but not really.

Depending on the size of your system, you can get a power supply for between $20 and $125.

I am willing to bet that it is the power supply. A cheap power supply can easily burn out.

System will not start up. Cpu fan spins once, then nothing.


It is more than likely that when your old power supply died a death, it damaged some components on the motherboard. Replace the Motherboard and chip, and you should be back in business. You can pick up some good value bundles to save money on buying the parts seperately. The power supply working again after turning off and on, is because there is a little trip in the power supply that triggers when it detects a fault. Powering down resets that trip allowing it to try and work again.

Good day, I inserted a memory into my second memory slot. When i plugged the unit, the slot started to smoke so i quickly removed the power cable. Since then the system has refused to start. The keyboard...


Hi there,

First of all does your power supply smell of burning?.... if so than you need a new power supply, otherwise you may have blown you motherboard which may include your cpu.

Please let me know what you find and I may be able to help you.

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.

You can try resetting the cmos/bios by unplugging the power cord. Open the case. Find the battery mounted on the board. Use a flat tip screw driver & lift out the battery. (About the size of a quarter). Wait about 15 seconds & pop the battery back onto the board. Plug you're power cord back in & power on the PC. If the system still does not boot, re-check all data & power connections for solid connection. Remove you're memory & firmely reseat. Try again. Still no? Replace power supply.
If the system still does not start & or gives no beeps, no LED lights & no fans power up. Than you're board is most likely dead. (So hate giving out bad news)

My asus p4s333-vm won't beep


you have basically replaced all the parts that could affect your system not to post. that would mean your motherboard is already damaged.
