[QUOTE=stealth6;382294]You say it worked before? Maybe the resolution just changed back?
Right click ET.exe -> Make shortcut
right click shortcut -> properties
Add to Target line:
+set r_mode -1 +set r_customwidth 1920 +set r_customwidth 1080
You might have to add +vid_restart on the end too, but not sure of that.[/QUOTE]
Thanks for your advice,But it did not work. 
[QUOTE=ailmanki;382342]The game worked once. Now it does always not - with same error as you say.
If you overclocked your system - that might be the culprit I suspect, else everything you did since ET worked once.
So you changed the resolution at first and since then its not working.
Do what stealth said, but I guess it will continue to crash. So then modify the shortcut again (fastest way to configure et and start with certain configs)
and
+set r_mode 4
thats sets resolution back to 800x600 - if the game works then - I would say your system is unstable - even if it works with newer games. Maybe a driver update can fix it aswell - but probably not.
edit: this is not based on my own experience, I read that last time I searched for your error, most likely it was DEP, but all other things pointed to defect RAM, or PSU not being strong enough…[/QUOTE]
My system has always been overclocked and its stable,I can play BF:BC2 maxed out and get over 100Fps in DX11,GTA IV i get around 55-60fps maxed out…i highly doubt its an unstable overclock or any of the issues you mentioned.
