So I have this computer which lags. It starts lagging after a while after I switch on my computer. I play Battlefield 3 and Call of Duty 4. The problem is that the framerate gets really choppy and it drives me crazy, especially when I am about to takedown someone. So i rage-quitted and found out that Windows is lagging too. A usual web page takes less than 10 seconds to load, but with the lag it takes about a minute. Closing programs also takes longer and sometimes it freezes for a while. I figured that it might be caused by overheating but I checked the temperature with EVGA Precision X and the temperature is only about 40-50 degrees Celsius. Here are my specs:
Try download Core Temp - it checks direct inside the core - you should check your GFX temp allso - there is some gadgets you can get to check your GFX .
Check your air inlets and outlets that they aren´t blocked with dust
Check if some drivers need updating
I downloaded the latest driver for my GT 610 but when I tried to update it, an error message saying '%1 is not a valid Win32 application' appears. I downloaded Core Temp too and temperature remains at 48 degrees Celsius max.
Well EVGA Precision also shows about 50 degrees Celsius for my GT 610. I used CCleaner and fixed all registry errors and cleaned up my system- removing temporary files etc. The lag seemed to have reduced and my computer functioned quicker, but the lag returns again after a period of time.
I also encountered another problem. While playing Battlefield 3 the monitor suddenly shows no input, but the computer remains switched on and running normally. The monitor becomes idle. I checked my graphics card( I took off the CPU case) and found out that the fan of the graphics card has stopped spinning.
