issue with graphics card?

If anyone who plays cod4 knows about the lagometer. well I recently bought the msi 1651 with the gts 160m nvidia graphics card, it has a 2.66 ghz dual core processor and 4 gb of ram. well while playing cod4 in the lagometer every like 10 seconds i get a second of lag and in the lagometer there is a blank space in the green lagometer line. does this mean my graphics card is turning off? if so how can i figure out whats wrong? i notice this lag in all other games i play. thanks a lot guys. if you guys cant figue it out i can call tech support.

 

nvm this lag is from network. but i am noticing lag in games like coh and call of duty world at war single player. even though it says i can run these games as recommended?

 

ok i now have confirmed that something is wrong with my laptop.even with all low setting on cod4 my laptop still has lag every couple of seconds? is there any way to test what is wrong? like is there a program that can analyze my laptop to figure whats wrong?

 

make sure when your gaming your power options are on high performance, also there is nothing you can do short of paying more money to speed up your network, make sure your laptop isnt overheating and if it is undervolt it and buy a cooling pad. oh yeah, make sure your virus scan isnt running.

 

ok i now realised what the problem is. a day or 2 after i got laptop i wanted to test battery so i changed the battery to powersaver mode . Thanks for the help josh.

 

Did it help with the lag?

 

yep. before i got lag even with all settings off or low. now i can run cod4 maxed out and still get 60 frames per second with zero lag. XD

 

i would also suggest you to update to the latest gpu drivers.
