I'm fairly new to computers, and this problem has been stumping me the entire day. I built my custom pc a little over a year ago. I'll give a quick list of my specs before I explain what problem ensues.
-Specs
intel i5-6600k skylake
msi geforce gtx 1070
msi z170a gaming m3 <---This is where the conflict will start
G.Skill - Ripjaws V Series 16GB (2 x 8GB) DDR4-2133 Memory
EVGA - SuperNOVA G2 650W 80+ Gold Certified Fully-Modular ATX Power Supply
Kingston - HyperX Fury 240GB 2.5" Solid State Drive
Corsair - H75 54.0 CFM Liquid CPU Cooler

Adding - Intel - Core i7-7700K 4.2GHz Quad-Core Processor

Throughout the time I've had this pc, it's been running perfectly. I recently wanted to upgrade my cpu from the i5-6600k to the i7-7700k. To do so, I had to flash install the new bios for my motherboard, as it was a generation behind the new cpu and couldn't read it without it. I got through the flash install and it booted up perfectly. I even went into the bios first before booting windows to double check the upgrade didn't have any corruptions. Once I booted up windows, I started noticing some weird but serious problems. It launched the desktop quickly, as usual, as the OS is on my SSD. However when I would click to launch programs, it would tend to lag for several seconds. Before this upgrade, that lag was unheard of for my pc. Then I started noticing more problems, such as there is no sound on my pc whatsoever. Using realtek, I have the same settings as I had before to use my headset. I select it and it plays no sound still. When I open youtube, it opens the site normally and has no issues until I try to play a video. It plays a video for 3 seconds and immediately stops. After that, it either continues to load with a black screen, or it plays a video at 1/2 the speed that it should even though the speed is on normal. I've checked all my drivers using both MSI Live Update 6 and comparing it to their website downloads themselves and everything is up to date.
That's all the information that I can think to give, if you need more to help evaluate the issue, please feel free to ask me and I'll get back to you as soon as I can.
 
Solution
Its a common requirement to reset a BIOS to defaults and SAVE after an upgrade. Check the readme for your BIOS update, or just do this. Slightly strange setting in bios might lead to lag/stutter, loss of USB devices, loss of MB devices.

You've ruled out overheating using HWMONITOR.

When swapping cpu's, I cleared off all the old thermal paste with isopropyl alcohol before applying more. I also checked to make sure I had no overheating issues on the cpu after booting up with CPUID also known as HWmonitor and it's at a decent 34 degrees Celsius when idle

Edit: I meant for this to be a reply, but I couldn't find the reply function while using my phone.

A bit of an update, I'm restoring windows 10 and resetting everything so hopefully it will re-optimize itself for the new cpu I'm using. With no other leads, I'm hoping the issue was that there was some discrepancies in the OS between the old and new Cpu's. Will post if it helps.
