The problem all started when I recently changed the frequency on my memory from 666 to 800 and now my computer will not boot and all that happens is my PSU fan turns on, my optical drive makes a sound and then everything turns off within one second. After about 3 seconds everything starts up again without me pressing any buttons, but then turns off quickly again.

I have tried resetting the BIOS and even removing the CMOS battery and replacing it. I tried removing all PCI cards and still have no luck.

I checked out all of my sticks of memory and they are all OK and have no damage to them, nor do any other components from my system.

I even tried changing the voltage on my PSU From 115 to 230 and the computer at least continues to run the fans without turning off within 1 second, but still will not boot.

I would appreciate any help.

Clear the CMOS by either removing the motherboard battery for a few minutes and then returning it /or/ by moving the jumper from pins 1 & 2 to pins 2 & 3 for a few minutes...then, put them back. Try it and see if this helps.

Be sure to ground yourself and have that unplugged from the wall before getting inside that case.

[changing the voltage on my PSU From 115 to 230]
this was not a wise move
see if you can borrow a quality 550w or better to try in it

i will try with another psu next week when i get back to school at the beginning of next week. hopefully this works. that was the only thing that I could think is wrong at this point.

ok so i tried with another PSU and got the same result. fans power on for about 1 second and then go off, and repeat this cycle until i unplug the power. i don't know what else could be wrong. Any suggestions? Thanks

set it up out of case where you can get a good look at everything

set it up out of the case on a piece of cardboard with
cpu
video
ram
speaker
and see if you get post
check you have the correct amount of standoffs no more no less
that they line up with the holes in the m/board
usually 9

it could be overheating would have the samw symptoms

redo the paste on the cpu with some arctic silver

ok i tried what you said and still no luck. I plugged everything in but still nothing. The computer just turns on then off right away.

Is it possible that my motherboard is "confused" as to the setting of the memory and is trying to run it at the improper frequency?

I can't think of what could be causing this. It was a simple change in the BIOS and resetting the BIOS and clearing the CMOS will not fix the problem.

ok i tried taking out the CMOS battery, pulling the plug from the back of the computer, taking the 24pin and 6pin power connectors from the mobo and held the power button for 5 seconds and left the CMOS out overnight and still no luck. The computer is doing exactly the same thing that it was doing before.

I even tried a stick of memory that is verified to work with the mobo and that did not work either.

Any more suggestions? Please.

dai

have you got it set up out of case with just the basics connected
check the cpu h/sink is secured ok

r0b3rt03

yes i tried setting it up outside of my case with only the power connected, the processor, processor fan, and 1 stick of memory in the slot closest to the processor.

I even tried taking the processor fan off, cleaning off the old paste and putting some more arctic silver on there and reseated the heatsink, but still go the same result.

still no luck, any other suggestions?

if you remove the ram and boot do you hear the error code it is missing
if not either there is not enough power or the m/b has a problem

r0b3rt03

yes when i took out the RAM and tried to boot there were 3 beeps which mean that the RAM is missing....when i put it back in I got the same result that I was getting....fans turn on for about 1 second and then turn off.

what was the other psu you tried it would need to be at least a quality 550 for onboard video or a basic video card

r0b3rt03

The PSU was a APEVIA WIN-500XSPX 500W ATX12V.

dai

low quality

even though it was not the best PSU it should still have been enough to power on the computer with no peripherals attached...a 300W PSU could've done that
