Hi Queepo, and welcome to TSF.

If nothing in the link Lord Sirian provided helps, please click on "Posting System Specs" in my signature, and follow the instructions to post your full specs for us. Then download Everest and SensorsView (both in my sig), and use them to record your temperatures and voltages (located under Computer -> Sensor in Everest). We will need to see 4 sets of numbers, 2 from each program:

+3.3V
+5V
+12V
CPU Temp
GPU Temp
Any other temps

Record first when the computer has just been started, and then record again after 10 - 15 minutes in CS:S (or when the lag starts happening).

Do you have any problems with any other games? If so, which ones and what problems (they may be related)?

Of course, follow the steps in that other thread first, as something there may solve it.
