i have been recently experiencing unusual fps lag in counter-strike and stuttering in youtube. This problem is kinda hard to explain so bare with me. Before my csgo ran at 55+ fps high - vHigh settings with aa, now it is unplayable dipping down to 20s, i've tried lowering settings but makes little difference. Lag is worst when people are firing at me. I have also experienced lag while watching youtube videos, the video stutters, produces static noises (crackles) and distorts audio when i move my mouse and using scroll wheel. I can replicate this lag alsmost everytime if i scrolling up and down when in Steam. I have also noticed Cpu usage spiking when i scroll in steam. Weird thing is when im playing league i do not experience this fps lag except at the end of a game where the nexus explodes my fps during the nexus explosion has decreased from usual, i think it has something to do with the loud noises.
Things i've tried:
Turning off and on. lol.
Updating drivers with driver booster 3.
Scanning for viruses using Panda, malwarebytes and windows defender.
replugging peripherals
using different peripherals
lowering game volume makes a very slight difference but sound is important in csgo.
temperatures are normal
everything stock
specs:
intel q6700 2.66 ghz / 40c idle/ 60c while in csgo
mb asus P5KPL-CM
4gb ram ddr2
gigabyte gtx 650 2gb factory overclocked/ 36c idle/ 55c in csgo
NO SOUND CARD
VIA HD audio
HDD old and nearly full
Windows 7 prof 64bit
Does anyone have ideas to fix this?
My last resort is to upgrade to windows 10.
