I don’t know how to describe this, but since reinstalled XP Pro new HDD etc due to HDD crash, just an hour ago reinstalled ET and the patch updated PB here is the fun part… soon as i try to heal anyone with the needle or use pliers as engineer ET almost goes into slow motion then screen goes black for half a sec.
Now if anybody asks i have all upto date drivers installed i don’t think its related, only difference is i installed NVIDIA nForce 3.13 drivers but game performance is fine its as soon i well description above… try to use any of the tools the game goes into slow motion then black screen and back to the game every time and running smoothly.
This never happened in the past, real pain in the ass when trying to fix people or build things 
Never had problem before with this on ATI Catalysts 3.9 tried 3.10 and same thing :o
Anyone have the faintest idea whats going on here? as i said game performance is fine, its just untill i use the med needle pliers and such this bug happens.
