New PC, random frames drops/lag spike for a few seconds..

[DarthRaider]

i recently got a brand new pc from cyberpower, its nothing insane it cost about $800

it has an win8 with amd fx 6300, 8gb ram, zotac geforce gtx750 1gb

this pc is fairly new like 1 week new i have about 4 games installed with a few other programs.

any game i run on normal/medium settings will run smoothly for about like like 10-30 mins and then it starts getting these random frames drops like 15-35 frames drop with lag spike like every couple mins. i also tried offline games and online games and its still the same so its not a connection issue. but some days itll be fine for a few hours and wont ever do it.

my cpu usage reading when im playing gta v is about 70-80% ram usage is about the same and my pc sits around 30c-40c when gaming..
i know gta v is a hard game to run on my type a pc but its not just that i could be playing somthing like counter strike or left for dead 2 where it dont use up a lot of cpu and dont have insane graphics and ill get that random frame drops.

in the background while im gaming i got steam, teamspeak and spotify up.

im not sure what would be causing this..it any ideas??

GTA-V - http://www.gamersnexus.net/game-bench/1905-gta-v-pc-fps-benchmark-graphics-cards#

Its not really the sort of game that you would be able to play too well.

At 1080p on High I'd expect max 40 fps average. On high action scenes that would drop to 20fps.

Start by stopping any additional apps from the background, including antivirus. Just Steam and the game. Then you can at least tell if it's some program that causes issues or a possible driver/hardware issue.

Only 1gb on the vga...if you also only got a HDD and no SSD then the vga's memory gets filled up forcing the system to swap data between hdd and vga mem,with the hdd beeing very slow it slows down your gameplay.

Try lowering texture quality to see if it gets better.
