Hello there, I used to be able to play gta 5 on my laptop with no lag (DELL Inspiron 15r 5537) which is: i7 4500u @ 1.8Ghz up to 2.4Ghz, 8GB ram, Direct X 11,1TB hdd, Windows 8. I was playing one night then my dad took my charger away (grounded). 1 month passed and he didnt give it back so I bought a generic one from memory express . I plugged it in and started my laptop. I started gta 5 and for some reason it started lagging and then my charcter had some weird pixely, transparent look( except for his clothes). could this be bcuz of the power cord getting replaced with a diff one and also whenever i play any sort of audio the speakers make a static noise which sucks. plz tell me what the reason is and if it is indeed the power cord
