Ok so I have a custom built PC; specs below:
CPU: Intel Core i7-4700 Motherboard: MSI Z97-G55 RAM: 16GB DDR3 Video Card: PNY nVidia GTX 770 Primary Hard Disk: Samsung 850 Evo Primary OS: Windows 8.1
For some reason, only semi-recently my computer has been super laggy and jittery. I have never seen a computer this bad since my days with Windows 98. Even with my CPU running at around 20% tops, only 30% of my RAM, and the hard disk is not being used, my computer is SUPER slow. For example, my mouse lags across the screen after a "freeze" delay. I have scanned my computer for viruses and malware and found nothing. I have been monitoring task manager and resource monitor with nothing.
I first noticed this issue when listening to music or watching a video. I also noticed that it only occurred when my network (Realtek ethernet on MB) was being utilized. Online results kept telling me it was my network driver, so I uninstalled it and found no improvement (if anything, it got worst). I have done countless searching online without any luck and now come to all you geniuses for help :).
And to clarify, all this is with pretty much nothing running, no games or anything.
Anyone have any suggestions as to what I can do before I rip my hair out?
Thank you Nathanial Meek for your suggestion to disable the network controller in the BIOS. I did that and the issue went away. I am using an old USB wireless adapter for now until my new network interface card arrives. Thank you all for your help and suggestions!
UPDATE: So I did purchase a decent Intel network adapter and the problem was fixed. However, now a month later the lagging and shuddering is becoming worst and worst everyday, and its all whenever the network is active. I have uninstalled the old drivers, installed new ones, ran many different virus scanners and malware detectors with no luck. I am completely perplexed. This should not be happening! Anyone have any other ideas?
