Noticed you are running direct-X 9 you might want to check to make sure C&C 3 doesnt require direct-x 10.
Go to your sys.information page and do a direct 3D test to see if it passes.if you know how i apologize in advance,if not go her start,all programs,asseccories,system tools,system iformation and clik.then clik on the tools tab and drop down to direct x diagnostic.open and wait for all sigs. to load.( bottom left)then test your direct draw and direct 3-D to see if they pass.
if so I sugest you check you virtual mem. on system info. main page and make sure you have at least 2 gigs and almost all that avalible. If this all looks good you probably need direct x10 because its the direct 3-D that is the initial error
Try start ,run,type msconfig and enter.go to start up and disable all then restart with this selective start up and nothing will run in the background to use up any mem.

but it sounds like a new game that may need 10

oh yea direct 3-D test is under your display tab....sorry

no, it wont be direct x 10, nothing uses it yet, in fact it'll still probably be another year and a bit before a game starts to use direct x 10. But I agree you should check directx diagnostics, there's an easier way, go to run and type dxdiag and it'll pull up the direct x diagnostics. I also noticed a kernel error in the picture you posted, not sure what caused that. Normally the kernel doesn't produce errors. Also it's not normally a good thing if the kernel is putting out errors. I can't think of what's causing the problem right now it's late, I just wanted to add this to the other guys post.

exactly the same problem, but i get a bit longer before it normally kicks me off, and sometimes it dosnt. it seems to be compleatly random when it does kick me off, and the error message normally changes size everytime i get it, sometimes a long list and sometimes only 5 or so items in the list of errors. tried maxing the virtual memory but it dosnt help. i have a 512 NVIDIA graphics card and 1GB RAM. please help someone.

I realise that this post is old, but I am now getting this error, - after changing my Graphics card from an ATI to an NVidea. My ATI worked very well, until it started to heat up due to age. I think I'll swap this one over for another ATI Radeon.
