There is a strange issue with my system and I am not able to figure why this is happening. I own a desktop which is not so old. It is a Compaq desktop with 4GB RAM and Intel Core 2 Duo cpu. I have a gpu also. I installed Battlefield 3 game in the same. The game lags in between sometime and also I face frequent disconnection error when I try to play online. I tried to check the same by playing other game. I installed WOW but the issue of lagging does not disappeared. Does CPU temperature is responsible for the same. I am having doubt on the same. I had checked in BIOS the cpu temperature at that time was on 70. But it remains fluctuating. How to deal with the issue. I had tried to re-install the game a number of time, but that does not looks like a software fault. What are the options I can try out here.
