what does the bios list your voltages as
im not sure but last night i unhooked everything with only the motherboard, and the cpu hooked up so it can't be the power supply, the computer turns on fan, dvd rom, harddrive are all working but no video out put
that's not an indication it's not the psu
what do you get in safe mode
if i only could of got to safe mode i get no video at all when i press the power button the monitor does nothing at all
nope the only noise i get is when i pull out the ram mem then only the motherboard beeps but theirs still no video
i think its a apex 430 watt but i pretty sure it's not the psu
no details available on it which is usually an indication they are not proud of it
it needs to be putting out 18 amps on the 12v+ line
see if you can borrow another one to try in it
well i tryed a diffrent psu still nothing im thinking i might have busted some fuse or something on the mob because the only thing that could be broken is the mob please do help
was the psu you tried better than the one you have in it
there are no fuses on the m/b
ye it was
Ok, I am intelfans friend and i will explain what the problem is exacly. When He presses the power button there is nothing on the monitor, it doesnt even register the signal from video card. But what I noticed is that the CPU fan is not spinning as fast as it suppose to be. It only spins at a slow speed. Everything is tested and working on different hardware, CPU, PSU, Videocard. I might say it was somewhat of a power failor or the chassis problem. I used to have the same problem, but my came up to life after i took off the MB battery. HIs is not. Maybe because it doesnt have a power failing protection.
I use P5E3 Asus Deluxe WI-FI Edition. He uses intel 478 socket motherboard.
Whats your opinion?
Yeah, this has happened to me. Your PSU bottlenecked or just can't handle that much.
You'll need a new one that's stronger, or just a better brand.
With my old computer, I added a new drive and checked everything out and it seemed to have enough power, but not all brands are reliable. Most everything turns on but nothing sounds right and nothing displays. I'm most certain it's the PSU.

Good Luck,
i tryed a diffrent psu with only the 20 pin motherboard and the 4 pin motherboard power wires hooked up still nothing. will a 700 watt work
try it and see
turn the computer off
remove the power lead from the back
take the side off
remove the cmos battery
move the cmos jumper from pins 1 and 2 to pin 2 and 3 and the back to pins 1 and 2
replace the battery
put the side on
replug in the power lead
boot the computer

there can be 2 solder points you touch with a screwdriver
2 pins you touch with a screwdriver or use a jumper
a cmos clear switch or button
there will be a diagram and instructions in your manual
if your getting the post beep it would indicate power
if no post beep
take the ram or the video card out and see if you get the bios beeps indicating it is missing
try the video card on another computer
with agp as long as there is 18amps or more output on the 12v+ line it should be sufficient
See less See more
well i found out the psu and cpu wasn't failing it somthing with the mob dose anyone know how to fix it without buying a new mob
set it up out of the case on a piece of cardboard with
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
well thanx for evry thing but i tryed it and still dont know what it needs i'll just try to get a new mob
