My PC when I orginally built it was processing and able to open apps and programs very fast and now it sometimes takes 15-20 seconds to open a program. Ive cleared memory and disks fragments and uninstalled quite a few programs and I just replaced the thermal paste just to make sure it wasnt the problem but nothing seemed to change. I am new to building PCs and I really could use some help with figuring out the problem. Thank You in advance!
