Question about ASUS P5B-E Motherboard
Pc was left on overnite , in the morning was just black screen and would not turn off with the restbutton .So i unpluged pc power , now when i turn it the light in on in the onboard led on the asus a7s8x-mx and the pc will not start up when i press the start button .
I have removed the on board battery for 24 hrs then tried again same senario .
i have removed all connetions to drives and removed all cards so it is only the mb connected with 1 stk ram and the amd sepron cpu( 8 months old )

Is there any one that can help please thank youcliee email@example.comI have the exact scenario and cannot figure out what's going on. I have the ASUS P5B-E and the problem i have now is that the computer seems "dead".
Before you started disconnecting everything, did you notice whether the CPU fan was running or not?
If it failed for any reason, the CPU is fried; none of them will tolerate the lack of cooling for very long.
Also, bad memory can freeze a system for sure; if you have friend using compatible memory, beg him to let you swap yours into his board and vice versa. I've found failed memory more times than I can count and finally learned to substitute early and save a lot of time troubleshooting stuff that wasn't broken.
It pays to own a cheap multimeter so you can check the individual voltages from the main supply since they can very surely fail piecemeal and any outputs used must be there otherwise the train won't leave the station. Most supplies will have the available outputs lised on them. Don't know in which country you reside but in the US, you can buy a usable digital meter for <$20 US any time and if near a Harbor Freight, they often have them for 3 lousy bucks.
BTW, the CMOS backup battery is way too young to have failed; three years is pretty much a minimum and I have replaced 8 year old batteries that finally couldn't hack it any longer.
I hope you know to take precautions before touching anything inside to discharge any static charge you might have from carpets or clothing. Touching any part of the bare metal chassis after gaining access is adequate.
