hey guys, i have a very strange problem. about a year ago after i bought my pc , i realized that after turning the kitchen ( far room ) light on/off my pc reacts like a usb was pluged and re pluged several times ( as long as the florescence light blinks ) - so i bought a ups ( emergency battery ) and still had the same thing as i thought the ups has a current stabilizer .
now after a year , one time when i switch the light on/off the ups started working - like there was an electricity fall. and the last 3 days while gaming and the light goes on or off i have the same sound ( usb plugin or out ) + lags .
what u think guys is the problem ?
