Hello everyone how is it going! First of all, I apologize as I think this is in the wrong section, but I couldn't find a " help section " to post in, so please bear with me as this problem is driving me up the wall and this computer is like 3 days old only. So I've built a new PC, specs : CPU : Core i5 3450 Mobo : Gigabyte P61A-D3 GPU : GTX 560 Ti RAM : 8 GB DDR3 RAM HDD : 1 TB HDD PSU : 700 Watts Cougar So I've been experiencing a periodic lag, which I noticed both normally and in a game ( Crysis 2, which is the only game I've been playing since I got this ). The computer freezes for a sec, then goes on. Also it occured in Crysis 2 twice, once it froze for a sec or two then continuted, the other time the FPS dropped from constant 60 FPS to something like 45 FPS for a sec or two then returned to 60 FPS. Also one time the computer totally froze and I had to do a reboot from the reset button. I tried updating the GPU drivers to latest, same problem. I think something is wrong and I'm not getting the max out of my PC, as it runs Crysis 2 on 50-60 FPS ( and sometimes drops to mid-late 40's ) only on 1280x1024 17'', V-sync on and hardcore settings ( and the benchmarks shows that it runs with better FPS on max settings and full HD, so it means that it must be something wrong ). Thanks in advance and all help is appreciated.
