Update your GPU's driver. Update all of your MOB's drivers.
Update Windows. If you have any OC disable it.
If it has it, update the game. Run a virus check. (You never know)
Use MS Security Essentials.
the link for the gpu does not work for me or the psu link also i got a bios update but it is a cap file and i do not know how to use it and my cpu usage is 98-85 that when my fps went to 60.... when it hit 98 again and went down to 56 fps
at first it was running smooth no stuttering but it still its low fps but it seems it takes more then 5-10mins to do so...i really do not know why this is happening was never like this i guess ill have to save money and buy this secound build i have made on pcparts.this time ill go with i7 and a gtx 770 superclock
My GPU never gets over 60C, so even 65C seems high for me.
Your GPU is at 152.6 degrees. Open your case and have a house fan blow on the GPU. (Fast fan)
If the problem goes away then your GPU may need more cooling.
