PC freeze, disconnect from the monitor

[domonx]

Hello

My monitor and speakers seems to disconnect from the pc when iam playing a pc game (GuildWars).  this seems to happend alot recently.  i was just playing a pc game and then suddenly it froze, my mouse can only go horizontally. then the monitor got disconnected 2 sec after it froze.  The pc is still on, but i can't see or hear anything and iam still connected to the internet.  my normal pc temp is 55C when not playing a game, and 61C when iam playing a pc game.  this problem started like last month but now it becomes more frequent.

i have window xp home edition sp2 and all the updates from MS.
ati 9800 pro 256mb for vidcard
2gig of ram
2HD
pentium4 3.0

thanks

I'm not too familiar with windows XP becaus I am using win 2000, but I may be able to offer some advice.
As far as the computer freezing up, that may be caused either by an issue such as spyware or something of the sort, or else it could have something to do with your system such as the pc running slowly and inefficiently due to fragmentation.
I experienced some problem of the sort whil playing Gunbound, the screen froze on me but I could still hear the sound and go between the desktop and the game, but I couldn't see anything or quit It and was forced to reboot. This was due to my system, but I also have an old computer and my hardware isn't exactly toop of the line either.
Can you tell me how long you have been running the computer? Also, did the monitor actually go blank, or did it just freeze?

this is a fairly new pc, and iam pretty sure its not a spyware or slow problem.  

my monito freeze for 2 second and it goes into the mode that it normally does when it lost connection to the pc, the "no signal" message appears...and i also can't hear anything from my speaker.  i got the lastest driver and everything too.  happend like alot tonight for some reason, it used to be like once a few days but it happend like 4 times in the last 5 hours.

thanks
