Having problems with your PC Desktops ?

While trying to resolve a power cord short issue on a Dell inspiron 5160 I removed all bottom and side screws and snap-in plate under power switch, removed monitor mounting hinges - trying to get access to a/c power receptacle. Could not get access. Put everything back together. PC now powers just fine, but lcd is dead. PC works fine with external monitor. I took care not to stress the monitor cable from pc to lcd (I thought). How do I troubleshoot the monitor?


Answers :

Sir first check num lock key on key bord if it is on and off then your cpu is ok
then when upower up the computer press F8 key then enter in enable vga mode then u can enterin winxp then change screen resolution to 1024*768 in display property.
But if num lock is not working then u have to open cpu cover and refix ram also try to clelar bios setup remove cmos cell from motherbord for 15 minutes then it reset.

There is a little ring terminal that needs to be connected to the chassis ground at a hinge screw.
