Computer wont start up

saintssuperstar · 15 Dec 2007 at 12:48

My pc wont start up at all. There seems to be power going to the mobo tho as the green light appears when its connected to the mains. I changed the psu with a spare one and it still does not work. Maybe its the mobo? if it is its the second one that has gone this year. Any ideas guys?

to reset the cmos is that when you take the battery out?

still a no luck

Yeah mate tried it with 2 different psu that work. Just tried cpu and mobo and it didnt boot.

All the power cables are hooked up :? and this problem just occured one day after I shut it down, not after upgrading it or messing around with the connections ill check anyway

The power cable connecting to the mobo does not fit all the pins, it is like 2 pins smaller i think. but its the same on my bros pc and he hasnt got any problems

bump still not turning on :s

saintssuperstar · 16 Dec 2007 at 14:41

standoffs? are they what the screws go into on the case?????

saintssuperstar · 16 Dec 2007 at 14:45

yeah they are on mate, the motherboard is not connected directly to the case

i did actually think myself it could be the case, i put all the component into another case and it didnt work either. i dont know whether the cas i tried still works cos its really old but it still didnt start up. Nothing happens at all when i turn on the power button
