    HP m1160n Media Center PC

    Bestec ATX-250-12Z rev D2 power supply

    Asus K8S-LA motherboard

    I had to do some electrical work in my office so I turned off the circuit breaker. When I turned it back on I assume I got a power surge...now my PC won't turn on. Power supply light flashes. I unplugged the motherboard connector and the PS light stays on steady. I plug the PS connector back into the MB and the light flashes again, PC still won't turn on. I also tried resetting the CMOS (moved the jumper over, etc.). Is this a PS problem or a motherboard problem?

Computer power supplys are modular replacement fixes. Better to replace the whole thing then try to repair.

If you didn't accidentally unplug the four pin connector near the CPU, you need to replace the power supply. This is actually a fairly common occurrence with the cheap ATX power supplies being tossed into systems these days.

the PSU has Problem . It is not supplying enough voltage to boot the PC, capacitors inside the PSU are weak or damaged. Its dangerus to open the PSU coz, Capacitors have high voltage currents.

But the replacement new PSU is better , perfect and cheaper then repairing the psu from outside. best of luck

Can you tell if the flashing is a pattern. count the flashes ( long and short) in a cycle. This will provide an error code to hopefully discover the problem.
You may also try removing and reseating the RAM and Video card, blowing out the connectors with compressed air before reseating.. Also look closely at the components on MB for any signs of swelling, leaking, burning etc. I suspect the MB.

if the cooling fan on your PSU power supply unit does'nt spin when you start your PSU is faulty if it does then
replace all the leads that attach to your hard drive including electrical extensions + IDE,SATA the ones that attach from your motherboard to hard drive
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?

Power supply light flashing green ,,, tried unplugging mother board still flashes green is it the power supply or the mother board?


Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacemnent from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

Computer will not turn on....how do I check to see if power supply is faulty? I have power supply removed and have a tester to check for dc voltage etc


I just went through a heap of troubleshooting with power supply issues before swapping psu's and finding this was the solution to my problem. Had a closer look at my psu that was faulty, the green light was flashing on the psu, unplugged all components and thought that I now had a non-flashing green light on my psu, on closer inspection the light was actually flashing very fast so appeared to be an almost solid light...the psu was stuffed so replaced it and no more issues. If your power supply has a green light check to see if it is flashing when plugged into voltage with nothing connected to it. If it is a solid light then it is probably ok.

Bad power supply?


Do yo have a volt meter or an atx psu tester?
you can check voltage to see

If a power supply is bad, your pc will turn off or/and turn on and turn off. As long as your system is running without and shut downs your good.

However if your pc is turing off, I would change it as soon as you can. basically what is happening, when you unplug everything there isn't much of a draw on power so the light remains steady, but when you plug devices in there is a draw and the PSU cannot deliver.

I hope this helps.

T5026 won't start up


Unplug the power cord, open the computer and disconnect all the power cables (the cables going from the power supply to motherboard and drives). Then reconnect the power cord and see if the light on the PSU comes on, if so disconnect the power cord and plug in the motherboard connectors and continue connecting components one by one to determine which may be the problem. If no power light with everything disconnected then the PSU needs replaced.

Flashing Green Light on Power BESTEC Power Supply


This is an easy fix so here you go nice and simple:

Problem: Your motherboard circuit has been cut.

Causes: Power disconnected during operation. Power outage or short in the surge protector.

Symptoms: Flashing green light on both motherboard and power supply. System will not power on.

Solution:

Step 1: Ensure that both the power supply and the motherboard lights are flashing green, not solid or off.
Step 2: While the power is on, disconnect the power supply from the motherboard. This connection is the largest of the connections and should be listed as the 'P1' or 'Primary' power connection.

Step 3: Wait until the green light on the motherboard stops flashing and check to ensure that the green light on the power supply is now solid. If it is not solid, disconnect the power to the power supply and wait until the light turns off completely. Then reconnect, it should be solid now.

Step 4: While the power is on, reconnect the P1 connection to the motherboard and you should now see that the light on the motherboard is solid.

Step 5: Power on your PC. The problem should not persist.

Warnings: If the power supply light remains flashing after you have restored power to it while it is disconnected from the motherboard, it may be a system failure in the power supply itself requiring replacement. Always be careful when working with an active or live power machine.

I hope this helped! Good luck!
