    The LED is probably indicating that you are getting +5V to the motherboard. The PSU may be having issues with the +12V rail. Have you added any hardware to the system lately? If so, have you exceeded the +12V rating of the PSU? Many of the fast graphics cards **** a lot of juice from the +12V rail and you may need to get a bigger PSU to support the card. There is also a large drain on iit, especially during startup, when the drives attempt to spin up and if you have multiple internal hard drives attempting to start at the same time, it can cause the same type of problem.

H!
Please check the lock of your processor. If it is tight or loose. If it is loose then it is the one causing the mother board no to function properly. You must tighten it to make it stable. After checking and it is not the reason for the malfunctioning of the system. Try to remove your CMOS battery and then clean, and remove also your memory card in the mother board and clean. Return it after cleaning and then close the CPU and turn it on. During the booting process strike the delete key to enter into bios set up. Adjust the time/ date settings to your current time. Press F10 then enter. wait for the CPU to process.

Please post any comment if it was solve so that I can give you more option if it does not solve your problem.

Will not power up. Replaced bad power supply(burned circuit board inside PSU) but still does not power up, PSU is ok. When power on button is pushed CPU fan turns for about 1/2 second but nothing else....


Sounds to me like when the power supply went out it allowed a surge to hit the mother board and you will have to replace it also .Look at the mother board and see if there is a green LED light showing if it is you are getting power to it and you have capacitors blown if not recheck you connections from the power supply and MB if they are all tight and correct then just figure on replacing the mother board

Cpu fan problem


If you plugged the replacement fan into the power supply instead of the "male plug on the mother board" you will get that error message. You need to find a fan that has the female plug for the mother board. It solved my problem.

No power,power supply seems ok,green light on mother board on. when pluged in the fan runs for a couple seconds and turns off.power button has no effect.


sounds like a mother board issue,

start with pulling out all ram chips and re try,,

then try pulling all cards out like old modem and also cdroms.

if ever thing but power is unpluged its a bad mother board or CPU chip

The purple light is flashing in the front and tries to start and won't turn on. disconnected power cord and held button in for thirty seconds still have same issue what could it be?


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.

This happens because your CPU is overheating, open your PC and blow any dust off the openings and CPU/Power supply fans, if you think one of the fans is not working... replace it.
