TF2 Crashing when taking screenshots!

[Bullet100]

[IMG]http://community.plus.net/wp-content/uploads/2009/02/team_fortress_2_group_photo.jpg[/IMG]

I've started playing TF2 again because of all the new hats and achievements, etc. Well like the title says...my TF2 likes to crash at random times. I am able to play for varying times, but it always seems to crash with the error '[B]hl2.exe has stopped running[/B]'. Recently I just got my GTX 280 RMA'd, and I do not believe that's the issue. Other games work fine such as 5 straight hours of L4D2.

[B]Some things I tried to fix the issue:[/B]
1. delete and re-install TF2 ([I]tried three times already, including manually deleting the files[/I])
2. reinstall/get latest drivers
3. disabling some background applications
4. disabling MOTD
5. disabling multicore rendering
6. Delete the 'tf' folder in HKEY_CURRENT_USER > Software > Valve > Source

[B]Some things I have yet to try (but doubt could be a solution):[/B]
1. lower quality settings ([I]haha yeah right xD[/I])([I]It seems to increase my play time before crashing though[/I])
2. reinstall Steam
3. not play at all
4. <Insert your solution here>

[B]My Specs:[/B]
Intel Core i7 920 @ 2.67GHz
Corsair XMS3 DDR3 1066Mhz (3x2GB)
NVIDIA (EVGA) GTX 280
Creative Sound Blaster X-fi
Windows 7 Professional 64-bit (6.1, Build 7600) (7600.win7_rtm.090713-1255)
ASUS P6T Deluxe V2

All I know is Re-Install steam otherwise its either a conflicting software or a hardware issue.

How come it only happens in TF2, and not L4D2? They both use hl2.exe to run. Also, how would I go about figuring out if it's a [I]'conflicting software or a hardware issue'[/I]?

1) Windows + R, type regedit
2) Go to HKEY_CURRENT_USER > Software > Wow64Node (I believe it's for some x64 systems, otherwise skip to the next folder) > Valve > Source
3) delete the "tf" folder

What's in that folder? I want to know if I'm deleting something important.

Listen to Max, he's a smart kid. I think he knows what's good or bad.

Video settings.

Ok, I deleted it, and it seemed to be working (about an hour of playtime which is longer than usual), but then it crashed when I have to reconnect to a server.

This is the first time I got this error message:
