No Power up on depressing On/Off button.

The PC has suddenly powered down for no apparent reason in the past with increasing frequency. Today, would not start at all; no sign of life, fans or lights ! Disconnected On/Off switch and found it open circuit. Thought " Gotcha!". Short circuited the two power sw. pins on MB, Nothing. Disconnected power supply and tried "Paper Clip Test" on 20 pin PSU connector (between green wire and black ).Fan started running. Checked voltages on plugs going to drives, approx 11.8 and 6.6vdc. What do I check next ?! Hopefuully not the price of a new GV20030812 MB!!

Boogiemaster is correct. I would replace it. checking it like that wont be accurate. It needs to load tested.

Sometimes if the CPU is overheatign it will power down to stop the cpu from buring out. A power suppluy just supplies power to the motherboard and that's it. If the CPU gets hot it shuts down and wont start till it cools down again.

Shuts down


This is a typical symptom of a failing power supply. Replace your power supply and see if the problem still persists.

Please notify me should you need any further assistance.

Since you have been use another PSU with no joy, i believe there is no problem with your all PSU. I recommend you to check your PC power switch for malfunction. In many cases this part is the culprit.

Computer comes on sometimes and sometimes just the fan

Maybe it is the ON/OFF switch. I have that problem with my computer once-in-a-while. Sometimes it won't power on or sometimes while it is on it shuts off. The reason I haven't done anything is because all I do is unplug the power cord from the back for about 30 seconds or so, plug it back in and It works. Not saying it is your problem but since it is free and worth a shot, try it.

ASUS 1005HA netbook suddenly always restarts

Good day sir/maam, the sudden restart of you notebook, may be cause by a sudden fluctuation of AC mains, it could also be cause by other sources such as nearby machineries. which boils down to the notebook's power supply module. Is it capable of supplying good descent power to your notebook. Try moving to other places, such as well at work or any place where you think there is stable power. Hope this helps. thanks

Power buttone notworking for Emachine T3624

Power problems are not always the power supply. A small amount of power is sent to the mobo to perform self test, and if the computer is ready, it signals the supply to turn on the rest of the power. That's to prevent a small problem from cascading into a large one. But it is difficult to troubleshoot. The problem could be with the mobo or the CPU. That's why you need to find a reliable repair shop with people who know what they are doing...not someone who only knows how to swap parts and calls that "troubleshooting."
