Team Fortress 2 won't work

As far as I know TF2 has yet to be made for 64bit and needs to be run in 32bit. But since I do not have any experience with 64bit Windows I cannot tell you how to do that.

But I did a little surfing and found something you may want to try as this guy seems to have had the same problem as you:

Thats the suggestion and it worked for the guy. Here is the link to the forum so you can read the whole thing:

I don't think its the RAID controller update you should be worried about but make sure the Nvidia network manager is not installed as that causes a lot of problems for people.

Good luck with everything man.

It's not an issue with 64bit Vista as I have been playing it flawlessly on Vista Home Premium (64) since I built my PC over a month ago. I've also installed all the updates that Neo listed and haven't had any problems (don't have a raid setup though).

Neo, what hardware are you using? I've had some strange crashes (usually in Crysis, but had 1 or 2 in some Valve games) that were apparently to do with my motherboard, but the latest bios seemed to help stop them.

Hey aziraphale what you need to do is bear the lagg and click on find servers then STOP them from refreshing, atleast this is what i did, i had the same problems as you. the problem for me was that it tried to refresh like a million servers at once, hope this helps!

Plow.

Hmmm....I don't think that's the problem, because the lag already starts an the main menu screen right after starting the game. I don't think it's already scanning for servers then; I also tried to disable SLI, changing video settings to the minimum, but it's very unnerving because the lag is so bad you have to wait a few secs for even the mouse to move; am I the only one with this problem?

Thanks for the tip; I'll try it rightaway!

PLOW TO THE RESCUE!

lol no problem mate, took me months to work that one out myself, seems like a common glitch :| and a bad one at that.

It would be interesting to see the OP post and see if what I posted worked for him.

I do tend to notice that Nvidias drivers for their mobos tend to like to mess with games and other stuff a lot.

Weird thing for me is I see all these issues for people and yet I have never run into any of them. Like the low FPS or this.

I do know for sure that certain Nvidia drivers like to wreak havok with TF2 for some unknown reason. If you go to the Steam TF2 forums you will read about some people who had to remove certain Nvidia programs or drivers to get TF2 working right.
