Hi, I have a big problem I despretly need help with!

First

specs:
1.3 GHz AMD Duron
Radeon 9250se 128mb ddr
384 mb ddr ram
SiS 7018 audio driver
ECS EliteGroup K7SEM mobo
Maxtor 6E040L0 38.2 GB harddrive

When I play games, pretty big ones, usually
my computer locks up and freezes nothign moves, keyboard dont work mouse dont work, and a loud humming sound comes out of the speakers. And once my moniter restarted and said out of frequency (moniter connected to vid card) then another time the game shut off and said ur VPU is reset(has to do with resetting vid card driver) but usually the game just locks up.. Any idea on the problemes? not enough ram? moniter probleme with hertz or something? drivers conflicting? any idea's??

Which operating system? Also, does your computer meet or beat the requirements that the game needs?

what is you refresh rate set to?check graphics card.....reseat it...

its at 200hertz but im pretty sure it can only go to 85hertz, and how do i reseat my vid card?

And I found out what the out of frequency error is, its my graphic card trying to make a bigger res and refresh rate then my moniter is set to, maybe thats causing the problem, how wud i fix that?
