Is anything else plugged in to the socket or surge protecter....and if so do those things power on?


If not it could either be the surge protector or maybe the circuit breaker shut off the outlet.
I thought the same thing initially but I didnt want to come off as a jerk by assuming he isnt intelligent enough to figure that out, but it is something that could be easily overlooked. Good idea.

Try single sticks of RAM in different slots. Also, try removing the GPU. I know you will not be able to see anything, but mine at least beeps when I pull the GPU. Unplug EVERY cable in your case and plug the essentials back in, one may be loose or have something blocking a connection. Also, make sure the power outlet works by plugging a lamp or something into it. Be sure the power switch on the PSU is on and set to the correct voltage. Some PSUs have a switch for changing from European (220v) power to American (110/120v) power. I have heard of people returning from American LAN parties and completely killing their PCs because they plugged it in when it was still set to American (120v) power.

Hey guys. I had to take out a case fan which had a stripped screw to get to the cmos switch lol, thats why it took so long this P5Q placement of important stuff is a bit weird. Anyway. I've cleared the CMOS and checked it was in the right place. This didnt bring any joy unfortunately.
I then removed all of the cable that werent essential, and tried the CMOS again.
I took out the Ram and tried to boot with no Ram, nothing, then cleared the CMOS again as i got in the habit lol
Tired it with one stick, another stick, then another, and then in a different slot.

Bearing in mind..

I...it was working fine for a week, moved into my new flat, ... turned it on and turned on it did, the windows loading screen came up fine, and then it just froze, a simple crash i thought, so i reset it and nothig was posted, blank screen (no picture), so i rset the BIOS and hoped for joy, but the screen was still blank. When i tryied again, it wouldnt even fire up...
It worked for a week, and i only went around the corner, have another PC in the same plug sockets that im typing on now (God I hate having 256 MB DDR ram grr lol)

There seems to be no budging it, ive tried it with no graphics as well Chicken and i got the same thing happen lol. I wish I had the opportunity to test the CPU and Ram, it would save a lot of aggro now oh dear haha. i gotta laugh about it

what do yall think it could be after all the diagnostics weve completed?

Bad power cables? This is really weird, the worst thing could be that its actually the board itself.

its gotta be something simple, I just cant place my finger on it at the moment. Can you post pics of your motherboard and setup by any chance? that may help us out a little bit.
post #16 of 19
It cant be that hard I guess, its gotta be one of a few things, power from the outlet, power from your power supply or a bad motherboard. Anything else would at least power on the fans, if you definately have power from the wall outlet your switch is on in the back of your psu and its set at 110v, you should be getting juice to your motherboard which would leave me to believe your motherboard is shot.

You can test your power supply by jumping the green wire to a black wire in the molex connector, if your power supply is good it will power anything plugged into it.

you really only need a fan connected to it.

remove everything from the mobo except the cpu fan connector and power cables(known working psu). those are the only things to be connected to the mobo. short the power pins for it to turn on the pc. if the cpu fan doesnt move at all your mobo is dead.

I thought it was 220v in UK. You would not want to switch to 110v and then plug into a 220v outlet (I have heard of bad things happening, like capacitors exploding, if this is done). I may be wrong though.

Yes you are very correct, he should not switch it to 110v as he does live in the UK and I had not realized it even though its plain as day, however transversely if his psu was set to 110v initially instead of 220v that could be a problem as well.
