Help Please: Computer Shuts off, green LED flashes Hello, Ive built a computer with an Athlon64 3200 processor, everything works perfectly however from time to time the computer just shuts off all of the sudden and the green LED starts to blink, I have to unplug the power cable for about 10 seconds from the bank of the computer and then I can start the computer again. My power supply is an Antec 350W I believe. Does anybody know what the problem is? Thank You Sina,
Sounds like your power settings are set incorrectly! Try turning System Stanby off! Also DO NOT unplug the power cable while it's on, the best way to reset after a system hang is to depress the power button for a few seconds or dimply press reset!
No its not a setting issue lol The computer just shuts off without any prior messeges, its not a windows thing. And once it goes off the only way to turn it back on is to unplug the power cable for about 10 seconds. While the computer cant be turned back on and before I unplug the power cable the GREEN LED blinks however the computer is not on.
Hi obviously cannot comment as there are not enough details. However this sounds like the behaviour of a thermal controled shut down.... Why? My mobo is equipt with U-COP. A utility which will shut the computer down when the CPU overheats. When it does that, the green led might still be on but the computer will not come back on until you unplug the power cable and re-plug it. Under-power PSU problems will usually result in a cycle of shuting down and powering up. Unless of course your PSU has had it. If you PSU has a thermal control shutdown, it might also result in the same symptoms. How new is it? What you need to do is try and note when the shutdowns actualy happen and what might be the temps of the various areas of your computer. I am sure anyone here can recomend one or two monitoring programs. Try Speedfan or Motherboard Monitor Good luck.....
Ok, I opened up the computer last night, It was really dusted inside; specially the fan and heatsink; and there was a wire in contact with the CPU fan which I assume explains the unordinary but small noise that I used to hear. Anyways I cleaned up the heatsink and fan, I have to go to Fry's and get one of those stickers to stick on the heatsink as the actual one was all worn out and stuck to both the HS and CPU. And to answer the questions, the computer is about a year old and it didnt start doing this right away. And there was too much dust or carpet thingies in it for a year old computer, Im not sure why but it sure did seem alot. Once I get that, Ill run the computer and update this thread. Thanks all, for your help Sina Loghavi
