I dont know what is going on! I put a new video card in (ATI RADEON 9550 256 MD DDR/ AGP 8x/4x) and added another 512 in memory. I have a P4 3.0 processor and every time that I go into Courtner Strike and play the processor fan seems to jump up in speed and lags out the game play. It will RUN at that speed for a min and then GOES back to normal. It will do that about every 5-10 min.  When I am not playing CS, it runs normal. I have installed the dirvers for it twice and now am lost at what to do next. Can someone HELP PLEASE!!! Fan up, game down, power supply?
How many watts?max output 250 watts.......There's a recent post in these forums that gives a link to a website to calculate your power requirements.
250W is very low.http://www.jscustompcs.com/power_supply/Fed is right, power supply wattage at 250 watts is a minimum. 500 watts or so is not uncommon these days.

Remember that the power supply will only run at 500 watts if you are drawing that much power. It does not mean that your consumption will double.

Use the Power Supply calculator to calculate the MAXIMUM with EVERYTHING running and add 10%.

If the problem persists try using a constant speed fan.Cool, i will try that and see if i need to get a new power system. Thanks for the help and great site!!!Hope you get it fixed. Let us know how you get on if you will.I put a 350 watts supply in there and it STILL does it??? Any other thoughts on this problem? Please any help would be awesome and thanks for the help!!and how do you set a constant speed fan?Are you playing this with a cdrom?
Are you sure it's the processor fan that's jumping up?
My processor fan runs at a constant speed...I think.
Never really looked.no, the game is on the hard drive....and when it happens i look and it the processor fan that kicks into high gear. Do you know how to set the fan speed higher.Just reading my mobo book here, mine can be set from bios and the default is the minimum setting.
Maybe you can SNOOP around in there or check your own mobo book.What type of connection are you using to connect to the Internet?The connection is DSL and  i have not idea ho9w to look around my bioes......
