Alright, this is my first post for the sole reason that I have no other place to go.
During winter of 07' I used to play a lot of CS:S after the new year I slowly quit, now after about 6 months I re-downloaded source and tried to play.
For the last 2 weeks I have had a unconsistant frame rate of 17-42FPS.
I find this strange considering in the winter I played at a consistant 35FPS.
I've tried everything; scripts, drivers, game accelerators, etc.
Nothing. So I have decided to ask you so caled experts

.
My system specs are,
3.33GHz processor
ATI Radeon X1050 video card with 256Mb of onboard DDR2
1 Gig of DDR2 Kingston memory
512Mb of DDR2 kingston memory
80mm case fans (LED)
400Wt power supply
100Gig SATA Hard drive
I think my rig is sufficient to run a low demand game on medium video requirements.
Tell me what you think.
