Firstly I'd like to say Hello and thank you for reading this in advance. When I arrived from the train I unpacked the desktop and noticed my heatsink was on the bottom of the tower unattached. I reattached it (fan working properly and seems ok), but in the process I noticed out of the 4 pins to hook to the board, 2 of them broke. My computer runs fine now, just whenever I open up any game / music program my pc goes crazy and lags and definitely doesn't run like it should. Is this due to the heatsink being without the 2 latches and not holding in properly, or maybe something else causing the computer to lag like crazy? It's driving my nuts how I can barely use my pc like I used to! Thanks.
