I'm having this problem that just started Today, yesterday Source was playing PERFECT...
today I started it and got these wierd graphics..
My system Specs:
*AMD Athlon XP 3000+
*FIC AU31 mobo
-(it's crap I know)
*1 gig Corsair XMS Pro
-(450/750 and I've tried not overclocking and it didn't help at all)
*160gb Samsung HD
All of my other games play PERFECT
farcry, doom3, max payne 2, splinter cell 2, call of duty, warcraft, ghost recon, halo, gta vc and 3..
I am using official 61.77 (please don't tell to try different drivers, because it was working fine yesterday using these drivers)
My cooling is really good.
CPU 38c idle 44c Load
Case 36 idle 40c Load
