    Same problem. Pulled the motherboard and found cheap capacitors on board. You will see that some of the capacitors have a domed top. This means that they have overheated and blown, internally. Either desolder the units and replace, or get a new board. The problem is widespread on different makers boards. The capacitors were of a very poor quallity and have a tendancy to overheat.

Check the capacitors on the motherboard. two or three years ago, alot of boards were affected by installation, in chinese factories, of very poor quality capacitors. To check, look at the top of the capacitors around the CPU, or feel them on the top. If they are domed, even slightly, then the capacitor is blown internally. You can replace them with better units or just replace the board.

Dear Kresten,
it looks like the problem with either your motherboard or SMPS. So, it is advisable to find a repairman in your
area. You can get the repairman in fixya itself.
thanks,

I turn on the computer and it may run some times for about 10 or 15 min. and then shut down i was wondering if i need a bio's update or what i have two hard drives in the computer xp pro on 1 and vista...


It could be overheating. After it shuts down, restart it, and enter BIOS SETUP, and look for a "PC Health" or "Status" entry on the menu. If you're lucky, it will report the current CPU temperature, and the speed of the fans, and the settable temperature at which it will shut itself down.

Check the capacitors on the motherboard -- any capacitor with a "dome" on top, instead of perfectly-flat, is a leaking capacitor that is intermittently failing.

Hello I have a ASUS P5S800-VM Motherboard with no HD on it just some RAM,graphics card,the CPU and a sound card.My problem is that whenever I switch it on it will stay on for about 15 seconds then shut...


There is no help for this, sounds like board has gone bad in one spot.
Why not use Windows to shut down the machine, or buy a surge supressor with individual switches.
Lastly, you could change out the Mboard with a new one, probable cost $40-$80 if you DIY - plenty of instructons on the WWW

Computer wont start(Plz Help me ) Added Much Detail as possiable


start by removing everything, ram, any cards plugged in, drives etc. Then try and boot it. If the issue is still present, shut it down and remove the heatsink and cpu. I have known CPU's to be jolted out of their sockets after an impact. Take the heatsink off, lift the lever and remove the cpu. Check that all the pins are still aligned and straighten any bent pins then refit the cpu and lock the lever down. Refit the heatsink making sure that the heat transfer pad or heatsink paste is still present and lock it down. Plug the power cords and front panel wiring back in and try and boot it. If it boots, shut down and refit each item you removed one at a time, booting in between each item. If the issue arises again, the last item you fitted is the culprit. If you can refit everything and boot the system up, lady luck is with you. If you still cannot get it to boot after refitting the cpu, replace the mainboard. Sorry but without special gear, locating a fault like this on a mainboard is a real pain..

Motherboard shuts off


You may want to try using another power supply rated at 300W plus. Also make sure your RAM is unbuffered and non-ECC. To set the switch correctly, you need to goto look at the exact model number of the CPU. Because CPU with similar marketing name could have different front side bus speed.

One more thing to look for, make sure there is no metal standoff sticking out of the bottom of the case shorting out the mother board. But my first guess is the power supply.

Newly built computer starts up without using switch


No signal means, monitor has not been connected. (for crt s) and, on startup (for lcd s) . Easiest solution should be, PLEASE REMOVE AND PLACE THE RAM TIGHTLY AGAIN. i hope, it will solve the problem, if you have recently traveled with your cpu.

Asus a8v-vm se fans always run


Hi jderek4, try this. locate the toggle switch on the back of the power supply. Just find it do not flip it.
Plug the PSU's power cord into the PC. Just as you got a good connection & the PC begains to power up move the toggle switch to it's other position. The PC should power off that very second.
If the PC does not shut off than the PSU is bad. If it did shut down wait a few seconds. Press the cases power on button. The PC should start to boot up. Let it finish loading. Click the start button & choose to shut down windows. The PC should shut off.
Yes? If not than your back to (bad power supply). Swap it out.
