Monitor Flickering off and on

[kenplus]

Hi everyone,when i turn on my computer it start to flicker on and off,a message show that there a missing autohnk file.Sometimes the screen freezes,the mouse icon disappear and the computer got a stop error message and is auto swtich off.

i try re-format my computer,change another monitor but the problem still occur.

I also try to change the setting such as the refresh, the acceleration and the resolution,the screen just freeze or start to flicker.

 

However when i use safe mode,everything is normal but when i change any display setting in safe mode,it start to flicker,freeze,etc

Anyone know what going on and encounter this problem before?Thanks in advance

I'm using Ms window XP home sp1
Intel Pentium 4 256mb ram
HP LCD flat monitor

Well , to start it wouldn't hurt to update to at least SP2 and upgrade your ram a bit. Check all connections, and reseat your video card, update your drivers.

I know this may sound silly cause i don't really do any upgrade unless problems occur,but which drivers should i upgrade,the graphics card or the monitor and where should i find it,any website to recommend?

i couldn't find any updated drivers from hp web,only the one that the same as my current ones,so should i uninstall the current one and re-install it?

I would check all the physical connections first and remove/reseat the vid card as suggested above...

As always when working inside the case remove all power sources and take static precautions.
