Since upgrading to Windows 8.1 from Windows 7 I have had issues with constant freezing. The freezes only last a second or two. It's most noticeable in games, where my FPS actually drops from 150+ to 10, but it also happens on the desktop. It's hard to track the frequency, it seems random. Sometimes it will happen multiple times in a 10 minute window, other times it will only be once every 20 minutes. I've watched the CPU, GPU and I/O usage and it doesn't seem to coincide with a spike or drop in any of them. Temps are also normal.
Things I've tried:
Reinstalling Windows 8.1
Reinstalling GPU, Motherboard and CPU drivers
Pulling a USB 3.0 PCIe card I put in around the time of the upgrade to Win 8.1
Here is my build:
CPU: Intel Core i5-4690K 3.5GHz Quad-Core Processor
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler
Motherboard: Gigabyte GA-Z97X-SLI ATX LGA1150 Motherboard
Memory: G.Skill Ripjaws X Series 16GB (4 x 4GB) DDR3-1600 Memory
Storage: Plextor M5P Series 128GB 2.5" Solid State Drive
Storage: Samsung Spinpoint F3 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: VisionTek Radeon HD 6970 2GB Video Card
Case: NZXT H440 (Black/Red) ATX Mid Tower Case
Power Supply: XFX Black Edition 750W 80+ Silver Certified Fully-Modular ATX Power Supply
Everything ran fine in Windows 7 so I can't imagine it's a hardware issue. Unfortunately, my Windows 7 key had been used too many times (WTF is this?) and when I reinstalled it told me it couldn't activate. I spoke with Microsoft's phone support who basically told me to bleep off and buy another copy. Despite being pretty pissed about the whole ordeal, I purchased 8.1. Now I'm stuck with a computer that can't play games.
Sorry for the little rant there, any help would be greatly appreciated. Thanks!
