Hi, Could anybody help ive just had to put a new psu in my friends pc, the original one was faulty cuz the red led on m/b would'nt light up. Put new 1 in and now it does but, the pc still wont start up. i have replaced the battery check all connections. as anybody got another idea. its a advent 3112 with ecs L4S5MG3 m/b.
ive had a simiar problem, where i was reinstalling windows, and it failed to reboot, i undone and reconnected all the connector, reseated the cards, still the same, i removed the bios battery, checked the voltage, <just under 3v> i put the battery back in.... still no go.. rechecked connections nope... went for a coffee, leaving it plugged in. just for the hell of it, i pushed the power button - and it booted! try leaving it plugged in for a while, it may help! anyone know why?
Unplug everything still nothin plug h/d in still nothing check the header panel on m/b make sure that was right with power button and thats fine. re-seated everything. Took battery out then tryed but the red led on m/b went off so had to put that back in.
Theres no point in putting the old psu back in as it did'nt work full stop.
I'm beinging to think that the problem lies with a fault on the m/b. On my last pc i had a short on the m/b and it caused a similar prob but it still did try and post notlike this.
Please pc god help me lol my friend is missing his comp.
no dont have a multimeter but my old man does and hes a test/repair engineer and im gonna get him to test it with meter. there was a tiny white mark unerneath the cpu on m/b where the tracks run on the pcb, could'nt tell if it was scratched off or what but i carnt really see it being that because its not as if it could get scratched underneath the cpu. Anyway of to get it tested.
Does anybody else agree that it sounds like a m/b or cpu fault?
