Windows 7 - Soldier Of Fortune 2 and Battlefield 2 problem

I have a wierd problem on Soldier of fortune 2 and battlefield 2..
I can play alternative times from 1 min to 4 hours on internet and after that screen freezes, but sounds works normally. after few seconds game just crashes without any error messages.

Both games does that same.
Had this problem on xp with same comp and with my old comp..

Any suggestions?

whats the networking setup?

Make sure you have the latest drivers. BF2 always crashed to desktop when I didn't have the latest motherboard driver years back.

Also make sure you have the lastest video and nic drivers like zig said

Install the newest bf2 patch which is 1.50 can be founds here

Well just installed newest drivers and sof2 stopped workin at all..

Ill install BF2 and update it, lost it because my hdd broke up like over a week ago..



Edit:
BF2 works great now..
Cant get Sof2 to work at all..


Edit2:
Found out that sof2 doesnt load on vista or win 7 if nvidia newest drivers are installed..

But TY for help, i will check this forum time after time..
