Freezescreens in all source games

[hildigrim]

Hi.
I've been playing HL2 since it was out, including HL2DM and CS:S.
Now, after a serious world of warcraft addiction, i wanted to recheck on my FPS skills, but seems I have a problem with the source games. Everytime I play a game running source, it freezes after a while, and I can still hear the last 0.3secs of audio playing over and over again.
Strange thing is, I play the games on the same computer I played em a couple of years ago, didn't change any hardware or settings ingame...

Anyone of you know what the problem is and how I should be able to fix it?

Thanks in advance

do all the non source games work?

haven't tried it yet, will do now, will post the answer.

Nonsource games not running in steam work, like fear, Wow, quake3

Ok, played Darwinia and it works absolutely perfect...

maybe your hardware started dying..

i have same probably, but many more toomy cs:s and hl2, both freeze in-game and while the game is loading. I have tried reformating my computer and installing the nwest drivers for my graphics card.

failed to lock vertex buffer CMeshDX8::LockVertexBuffer

This instruction at "0x77279afb" referenced memory at "0x7dc48950". The memory could not be "read"

Terminate Program...

these are the main errors that come up and i would appreciate if any1 could help me fix my games, as i have bought them off of steam with the last 2 motnhs, i am really unhappy that i bought a game and it doesnt work
