need help monitor keeps restarting?

Ok this is driving me a tad nuts

All day today while working my monitor keeps shutting off and restarting in a different size??
I have no clue what is causing it?
is a compaq that I caught used

the system is Windows XP pro No service pack 2
the computer is a home built one
it I a AMD anthlon 2400
1.99 GHZ
80 gig hard drive
1 gig memory
with a radeon 9200 video card
unsure what else you need but just ask

Could someone have put something on here to cause this?
I ran ad aware cleaned it out
about to add spybot and run it too

Any advice
is appreciated

Could be a bad video card driver!!!

Try uninstalling and reinstalling the video driver!!

check the refresh rate and make sure it is compatible with your monitors resolution specs and lowering it if need be, you or something may have set it to a rate that which your monitor cannot produce the resolution you want so it switches it self automatically to lower resolution

 

i think it has to do with the video card or its drivers... some older screens turn off and back on when changeing resolution so i think ur pec is switching resolutions all the time.. try different desktop resolutions...u might get rid of it.

 

thank you I will try it

 

Thank You So much
I am really unsure why the settings had changed on their own but then it may have been the kids.
Anyway I hooked the So called broken one in changed display settings Now it is working perfectly fine
I can not believe I almost spent money to buy a new one that was not needed.

I can NOT thank you enough for saving me that money.


Many Many Thanks,
April
