Computer Freezes When playing Games?

[rogeroo]

Problem:
I am setting up a second computer for my children to use and primarily play games on.I did a clean fresh install of Windows 98SE and all works fine except when they try to play a game.The system runs fine for hours until they play any games.When a game is started it loads and runs fine for about a minute or 2 then the whole system locks up and the only way out is to cold boot.Ctrl-alt-del does nothing.I have tried using different versions of graphics drivers but always the same result.The game requirements are all under 400mhz p2 and the graphics card should be way more than sufficient.The graphics card is good because i used to have it installed in a different comp previous to this one and never had any problems with it.I have tried lowering the hardware acceleration but the same problem exists.Any help would be greatly appreciated , Thanks .It definitely is not a heat issue as the card itself has a running fan and i had the cover off with a house fan blowing and the game froze right away.

Make -ASUS P2B-B motherboard with the latest Bios update installed.
CPU - Pentium II 400 mz
Ram- 2 X 128 mb Sdram
Hard Drive - Maxtor 20 g 7200 rpm (free space 18 + gb)

Graphics Card- Geforce 2 MX 400 64 mb Nvidia with the latest Detonator drivers installed.

Try going back to an older detonator driver... I know I had troubles with the new detonator drivers installed on my comp and had to stick with the last version due to games crashing and freezing.

Even though you did try some older versions, go way back and start at the begining and see what happens...

what kinda games are you playing?...are they graphically intensive?
i have a GeForce4 MX440 and i have to revert to the driver windows XP supplies me with because some of my games hang on start up.i cant use the new detonator drivers.

Try running the system with the case open to see if heat is causing the lock ups.

Well thanks for the help m8's.Tried swapping ram with no change in the games freezing so i don't think it was a ram thing.I updated everything from video drivers to chipset drivers to direct X and nothing helped.It's definitely not a heat issue as the card has a fan on it thats working and i also took off the cover and had a house fan blowing on the whole works and still the games freeze the comp.I finally went and picked up a Voodoo 3DFX 16 mg card for 15 bucks and the games now work with no problems (go figure)The only thing i can think of is maybe i somehow messed up the Geforce card when swapping it.I will have to test it out on my other system later (i have had enough hardware swaaping for a while)Thanks again.

When you touched your video card to swap it, where you grounded to something to keep static from shocking your card?
