hello, Today i encountered a problem while starting my computer. my monitor keyboard and mouse are not working. first i checked the monitorand it was plugged in and i made sure monitor is okay. when i started computer, then i saw that monitor is not displaying anything. usually after 1 or 2 second, it starts displaying but today no display was available. i waited long time but no display. Immediately i realised that, when operating computer, mouse and keyboard lights are not showing. (for mouse it is red light below it), then i confirmed that my ports are not working. i tried removing CMOS battery then again put it back correctly, removed the ram from the slot and put it back again and i alsi checked if my motherboard is okay by starting computer without ram. and i got beep beep sound and made sure it was alright, then i pluggued out monitors cable from cpu and i saw a messege showing monitor is not working. my fans are spinning, i see everything normal as before except monitor mose and keyboard, i tried plugging in mouse and keyboard in all ports but still not working.
One thing should be mentioned here, i have been getting CMOS battery failure massege feom one month, thats why when i had to start the computer, i had to press enter to procced. but now without keyboard i cant do that.
I have been searching for answer for 4 hours, but found no suitable answer. Please help me..i am badly in nees of help..please....i know my mobo is not dead....my power supply unit is not dead...please help me
