Having problems with your HP Pavilion a1540n PC Desktop ?

Whenever i turn on my pc it says no input signal.i dont know whats wrong with it.is it the motherboard or the hard drive?


Answers :

When you power up the cpu check your smps is working?
Then check num lock key on key bord if it is on and off when you press numlock then your cpu gives dispaly to monitor ok.
but if it not constant on or off no change when you press num lock key then you have to open cpu cabinet.
Refix RAM memory .
Clean dust from motherbord chipset.
Pull out cmos cell for 15 minutes so bios settings are reset to defaults.
then check.
refix all connection to mothebord like ATX power supply from smps.
Does your computer boot at all? meaning do you see the bios data, hard\015\012drives, ect? or maybe a logo like compac or dell? when it boots look at the tower is it doing anything? my best guess is its booting and the reason your getting that message ( no input signal ) is because your video card has died. I could be wrong because it will give you the same message if your computer died its your monitors way of saying ( I'm not receiving a signal am I supposed to be?) I hope this helps please let me know..
