So I play video games, edit, etc with my PC. It's a mid range custom PC. I used to get very consistent and fast performance. Now, in Minecraft I get 40-180 fps with constant dips into the 20's. In BF4, on high without AA/AO, I get 50 fps with dips into the 10-20 range. This used to never happen. Now, it's common and super annoying. I tried overclocking, underclocking and all of that and nothing worked.
My specs are as follows:
CPU: FX 8350 4.0 GHz
GPU: MSi R9 270 2GB Gaming
RAM: 8 GB Kingston Hyper X Black
Mobo: Asus m5a78l-m/usb3
OS: Win 7 Ultimate

Might be a driver issue i would do one of two things download the latest drivers if any new ones are available or back date to the drivers to the time when you were not have these problems.
2nd less common problem your HDD could be going bad causing slow performance (transfer rates) but you would be getting random errors/crashing.
