It's strange since this problem has seemed to have gotten progressively worse over the past 2 months.

It's a custom build, so if it's a hardware problem, I'll change it out. My system is: Windows 8.1, 8GB RAM, OS on 128GB SSD, a 1TB hard drive, a 500GB hard drive, Nvidia GTX 650.

These problems happened very rarely before April. In that month, I had a Microsoft support guy do a specific reinstall of the OS that didn't remove installed programs or settings.

 

It's really annoying because at least twice a day, the mouse and keyboard just stop responding - and the keyboard even while holding a key sometimes. The mouse and keyboard were connected via USB at the bcak on one pair of slots but I moved them to another. I have a 2.4 GHz Wireless adapter connected to my front USB slots because then I can move the mouse again and put the computer to sleep. Then I can wake the system back.

 

Okay, I'm probably explaining things really poorly...

 

Mouse and Keyboard frequently disconnect and reconnect throughout the day. The Windows sound for disconnected hardware plays.

2+ times the hardware does not wake and a second mouse is required to put the computer to sleep so the hardware wakes properly.

 

All power management settings regarding that hardware have been disabled in Device Manager.

 

Webcam seems to function normally and is also connected in the back.

 

USB Ports for the mouse and keyboard have been moved.

 

 

What do I do? It's so annoying.

I suspect the MB. But you can also check the Power Options in the Control Panel and see how they are set. There are also, usually, power options in the BIOS, so check those too.

I can see USB suspension in the Power Savings menu, but it's set to disabled. Let me check the BIOS for USB options.

Might be related but today instead of just disconnecting the hardware, I got a blue screen regarding lvrs64.sys and ntoskrnl.exe
