Sometimes, only the f,g,h,j,k keys do not type
Starting about a month ago, I had this recurring problem where only a few keys would not enter a letter when typing. It's only (I think) the F, G, H, J, K keys. Sometimes it goes away, sometimes it stays until I reboot.
At first I thought it was related to some fishy sites I browsed in Portable Firefox using SandboxIE. When I terminated all programs in SandboxIE, I would get control of those keys after a few minutes.
Today when I booted up my PC, I had this occur right from the beginning. I ran scans in MS Security Essentials (don't laugh, please) and MalwareBytes. Nothing bad came up, so after a reboot, all seemed fine.
Odd Thing #1: Two hours later, after I had been browsing 'normal sites' in Chrome only (No SandboxIE, just normal Google, TomsHardware, Youtube, Amazon) I found it happened again.
I decided to play a movie on a second monitor while trying things out.
Odd Thing #2: Microsoft's On-Screen Keyboard does NOT register those keys (letter K for example) as a typed letter in an explorer window, browser, or start menu search.
Odd Thing #3: VLC recognized me clicking madly at the K button as setting the audio delay ahead on the movie!
Odd Thing #4: When I closed VLC, the problem stopped.
The problem did not come back when I played the movie in MPC-HC.
I don't think it's due to maxing my older system. This happened before I started playing Fallout 4 at 1080p medium settings. VLC plus some Chrome tabs only used 15% CPU / 3.8gb of 16gb. MPC-HC only used 9% CPU.
No hardware changes were made in the last several months aside from a gaming mouse in August. I am using a 5 year old MS X6 gaming keyboard and I tried an even older Acer OEM keyboard (both USB) and neither keyboard would type F, G, H, J, K keys.
I have a quad-core I5-750, 16gb DDR3, and an SSD for Windows, programs and games.
Help? Thanks in advance!
