Need a Hero! CPU/Internet Issue.

[P.T Networx Australia]

Good Day, Young Sirs.

I have an issue with my PC which I've had for quite a while and I've never seemed to be able to fix it. 
My strong belief is that it has something to do with the CPU Cache. But i could be wrong, Which is why I'm asking on here incase someone else knows the issue. 

First of all, Here's what I'm running. 

MB: Asus P9x79-LE
CPU: Core I7-3820 @ 4.7Ghz 
RAM: 32GB Trident-X DDR3 2400Mhz
Graphics: Asus GTX670
SSD: 512gb Samsung 840 Pro
HDD: 4 TB WD Black
WIFI: Asus PCE AC68
Case: Coolermaster Cosmos II


So, Here's the issue/scenario.

Lets say I listen to music while I'm working, 
I put my PC to sleep at the end of the day and wake it up the next day and do that 2 or 3 times 
before the issue starts to occur. Then for some reason when i load a webpage the music kinda freezes or jitters if that a word. 
I also notice the mouse starts to lag a bit until the page is fully loaded. once the page is loaded everything is fine, it only seems to happen
when the PC downloads/uploads. 

I had a feeling it could've been my expensive and not so typical PCI wireless Card so i tried ethernet and it still gave me the same issue. 
If it makes any difference my bandwidth speed is 100Mbps/12.5MB/ps which Is precisely why I have the PCI Wireless Card that I have so I can take advantage of the internet speed I have.

The only way to stop the jittering etc is to completely reboot the PC. Which isn't that much of a big deal but it's just annoying to save everything and reboot, then open everything up again etc. 
And being a web designer kinda makes it more annoying because I'd have a million web pages open hence why i have a 21:9 monitor too. Lol. 

It's also why I though that it could be the CPU Cache, From my years in the IT industry i believe you can't flush the CPU Cache without restarting the PC. It's a bit like ROM back in the day. 

If you need any more info let me know, I'd really like to get this issue fixed. 

Regards, 
Petru

could you check your ram usage

could you check your ram usage

With a busy task load the CPU sits at about 7% and ram usage is just over 4GB on average. 

HDD is also on a low load.

Not sure if I can bump this yet...
