Hi, i have just replaced my psu, as my pc would not boot up. But it still wont boot, not even a bleep, all fans are working, motherboard, graphics etc. Is there a way of checking components 1 by 1 to check which has failed ?. i can here the hard drive, but do you think that the motherboard may have had it when the psu packed up.

Did it Beep Before?

Remove the Cable Plugs From Hard Drive then see if it will show anything on screen. As I had a Drive go like that, and it was just nothing on the computer not a sound

"all fans are working, motherboard, graphics etc"

how far does it get?
what is the last thing on the screen?

Hi all, yes it bleep with my old psu, i have tried an old hard drive that used to work out of old computer. Will it work even though this hard drive has been wiped clean ?.All i get at the moment is all fans working, and screen says no signal, nothing else.

Hi again, as above it switches on and thats it, nothing on screen just comes up no signal. But i have noticed that i cannot switch of now using the on/of switch on the computer, bet it is the motherboard, just wish there was a way of knowing.

"screen says no signal"

check cables and connection pins
remove, refit graphics card and retry
if on board graphics reset BIOS by using clear BIOS jumper or by removing battery for 10 minutes.

Hi Fruit Bat, i will now try all of the above, remove and refit everything. Still cant help thinking mb has gone, but not giving up yet. PC was built by me and everything work first time, must be missing something.

P.S i am trying to fix pc on table so only have monitor connected at moment, would connecting everything make a difference ?. i.e no keyboard sounds cables etc.
Thxs for trying to help, im lost without my desktop, and hate using laptops.

If you disconnect everything, then when you turn on,there should be no end of beeps if motherboard OK

need minimum
psu, motherboard, cpu and fan, memory (1 stick, graphics card + monitor, keyboard + mouse

momentarily short across pins to start switch to activate PSU, it should then boot to error maessage no disk drive or opsystem missing

shut down add hard drive and retry.
