PC periodically freezes and restarts while playing WoW

Ever since installing my new video card and World of Warcraft my computer regular locks up or completely restarts while playing the game. The video card is an ATI Radeon 9550 256MB and my computer is a Pentium III, 866Mhz with 768 DDR RAM and I'm running Windows XP Professional SP2. I went to the ATI website and downloaded and installed the most up to date drivers but it hasn't changed anything. My computer has yet to lock up while not playing WoW, it only happens in game.

And it doesn't seem to be an issue with there being to much going on onscreen. I've got the game set to run at 1024x768 and most of the settings are set to the lowest they can go. And even with these settings fighting a simple creature one-on-one can result in a lock up or reset. Can anyone help me out with a solution? I'm going to invest in a completely new PC for or after Christmas but until then I'd really like to play WoW without locking up every 30-60 minutes.

 

Have you set all the settings to low including changing the multisample to 1x and disabling full screen glow effect? Do you get the same problem in other games or is it just WoW specific. It could be an issue with your GFX card if it happens in other games too. It could also be a cooling issue with your GFX card too, can you monitor the temperature in the catalyst control centre? These are the things I can think of off the top of my head.

Your PC is relatively slowish, WoW is a recent game and so demands a more up to date system despite what the minimum specs tell you and you should have alot of the settings turned down. This being said I doubt it should cause lock ups.

 

maybe you should go to the WoW home page and go to trouble shooting. It's really helpfull.
