Unfortunately, that could kind of be... Anything.

Do virus and spyware scans, re-download or re-install what you've got as far as Steam and your Source games, kill background processes... There's a lot of boring things you'd need to do to try and root out the problem, but with so little information, I can't give you a specific solution. =/

Try downloading a free [link=http://www.memtest86.com]memory testing program[/link] to check your RAM and see if it's faulty? Make sure your computer's not running hot (proper ventilation, no dust buildup in heat sinks or fan filters), turn the air conditioning on if the room you play in is hot. Heat actually does cause errors like that on occasion, my wife's computer gets 'em sometimes.

Yeah, that's pretty vague.

Where it says "click here", do that and give us what is there- might be more informative.

I had that problem.

Maybe it's not responding?

well i just reformatted my computer so i dont think there are any viruses or spyware, i remember having this problem before but it was because of the steam update and it was fixed after another steam update, and how do i do that memory testing program?(yes i sound stupid )

EDIT: ok i finally got it to run! no need to post here anymore thanks!

Go to the command prompt (hit run and type in cmd.exe)
and type this in:

net localgroup Administrators /add Local Service

(optional)
then you can type this in:

net localgroup Administrators

and if LOCAL NT AUTHORITY/SERVICE is listed, then it worked. Now go reboot.

fixed my problem easily
