When ever i play a game whit low req such as Warcraft 3, after 5min my comp freeze, screen turn black, then i have to reboot, i did Spyware doctor, registry mechanic n error doctor.. nothing help!!

Window XP sp1
Geforce 4 mx4000
384ram
AMD duron(tm) processor, MMX, 3Dnow, ~950mhz

thanks

Is this a new problem? Were things working OK previously? Any new hardware and or software?

Could be a temperature problem. Have you cleaned the inside of the computer? Checked the fans?

I clean inside my comp regulary, only have 1 single fan.
I always had issue whit it, random crash when i play various game...
Every after i reboot it, i log into a game and the interface turn invisible, i close the game n relaunch and it ok untill next reboot.
i tough it might be my video card unstable but what do i know..i had it for over a years and it always been this way

i just added a 128ram hopin it will fix my problem, but no change sadly

I tough to post here incase anybody had such case before n could help, thank
