Recently i switched from GTX 750ti to GTX 1050ti and installed a new thermaltake 500W power supply, after installing the new parts i installed the windows 7.When i fired up my pc the first thing i noticed was that my recommend resolution for my dell e2014h monitor has changed, before the upgrade it use to be 1600*900 but now it is 1024*728, i use a hdmi to vga adapter. After installing all the necessary drivers and settings ,to test the performance i ran CSGO and it was lagging terribly pre-upgrade fps was 90-115 average , but after upgrade it has become unplayable and fps is 20 - 30 and the pc overall has became laggy. I don't have a clue what went wrong and any help would be appreciated.
