left 4 dead 2 won't run

My problem sounds similar to the guy w/ the mac. I bought a new HP gaming system.

Specs:
HPE-170f
9GB Memory
Processor: Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz
Video Card: GeForce GTX 260, Memory 1.75 GB

Installed steam and L4D2. Won't boot, but doesn't crash. Completely reloaded everything after wiping steam. Still won't boot. Tried every compatibility mode. No behavior change. Loaded updated video card driver. No change. Ughh. Any suggestions?

Huh.. LFD2 runs fine on my new system. I'll do a little research for you. system specs at the bottom left hand corner.

Might find something here to help you out.. 4th Sticky at the top

Thanks for assist Greyno, but I've been through that post. I don't see the steam client service running when steam is running, but even if I start up the service in the services manager when steam is running, the behavior is the same. Wierd thing is, the problem doesn't throw an error to any log I can find (including event logger).

Thanks for redirect though. I appreciate any any other advice.

Go Zags, (my bears won tonight as well)!

Hi owen,

Could you elaborate a little more on "My problem sounds similar to the guy w/ the mac."
Have you tried deleting the clientregistry.blob?

Yes I have! And it's a good suggestion. Works for many problems, and I've used it before.

This problem I have is odd. Two weeks of internet trolling by a mid level user, and I'm still stumped.

When I try to launch steam games, the game starts to load, but stops. It throws no error. Not in event logger, nor in any steam log file. There was a guy with a mac that had a very similar problem. See the trailing. He solved it w/ a driver fix.

His thread trails. Left 4 Dead Won't Run With Windows 7 Home on Mac *help*

I've posted more details in a steam forum.

Steam games not loading - Steam Users' Forums

I'm offering a $20 reward to the person that finds the solution. Good hunting!!!

Will do, but I've done that twice already. What the heck, can't hurt to try. I do have some new info though.

I downloaded a demo for a non steam game (through steam) and downloaded the half life 2 demo. Walla!!!! both run!!!

So, this is some lame steam problem with new games and a relatively new pc.

Downloading we go.................

oh, btw, it's not just l4d2 that won't run. l4d won't run, tf2 wont run. Sounds so very much like a steam problem.. why does steam support suck so bad???
