Can anyone here help to solve my PC gaming freezing/lag problem?

What are all of the games that are causing the issues? Have you updated your sound drivers?

Try playing the games that have this issue with sound disabled (not just muted on your end, but actually disabled), and see if the issues still occur.

What are your specs as well?

Close all programs for play or u can back to the old drivers graphics card, or just format or directly change u computer

It might be because of your avatar.

Yeah sounds like a audio driver/card problem, in the old days these were known to cause all sorts of problems similar to that and still do on the rare occasion now, if you have access to a pci sound card (and your using integrated sound) you might want to try switching it out to see if it works, honestly if counter strike causes it I highly doubt its overheating problems. could also be harddrive load issues (try a smart test) but I doubt that.

Also if the games let you limit the number of sounds try lowering that, unfortunately most modern games don't.

I would definitely open the case and remove any dust in there, in addition to updating your drivers. Even if your graphics card was working a few months ago, if it's clogged with dust and overheating... you could melt it.

Clean the internals of your computer. Dust.

1. Whats your hardware?

2. Whats your idle/load temperature?

(Use either Speccy or HWMonitor for getting this information quickly.)

So I went into my sound drivers to find out what update I needed and it turns out I have 4 of the same type of High Definition Audio driver? Is this a problem, or why do I have so many?

I was thinking it could be your hard drive that is failing... couse hard drive does interfere with sounds sometimes... and that could couse lagging and other problems too.

That comman problem with most cheap laptop becuase they have Poor Graphics Device and Poor Audio Device and Slow Harddrive.
The crackling buzz sound maybe a bus mastering problem have try update your audio driver?.
What is your system spec all that helps we need make and model gose a long in help solve the problem.
You know that what Steam Users's Forums is for it called "Hardware and Operating Systems".

So, I realize this may be an odd answer and it's probably not right. But with Source games, such as TF2 when I overclock my video card too far maybe every 10 seconds my game stops for 10 seconds and repeats the same sound and it loops very annoyingly. That's what happens instead of artifacts with Source engine. Also, it would help if you gave us the specifics of your system.

I HAVE SAME PROBLEM!! I think its something with CPU. Try run a CPU test if your PC will lag or will freeze during the test its definitely a cpu problem...or maybe a power source problem..If you want quick help for some games like Portal 2, L4D 2...etc. disable Multicore rendering in game menu. Problem is that not many games have this option (I love Valve because they have it in every game) I have this problem for 2 years and still I dont know how to fix it permanently...maybe new CPU or power source... :-/

Go to "Playback Devices" (Controp Panel -> Sound), Select "Speakers", click "Properties", and in the advanced tab change the default format to 16 bit, 48000 Hz and disable exclusive mode. Now click OK and do the same with your default recording device (should be the microphone). It's very important that playback and recording quality are the same. After ensuring that this worked you can raise the quality (always with the same value in both devices) to see how much you can attain without choking your system. Good luck.
