Hello lovely people,

The weirdest thing is happening to my system lately. I can't identify whether this is a software or hardware issue and by hardware I mean.. motherboard fault. Recently my rig would assume that I'm pressing the "D" key on keyboard permanently. This happens randomly and there's no specific time window of when it stops. Please refer to the video provided below:

Watched the video and saw DDDD long after boot. Read his post, did not read his comments on the youtube video or use sound when watching the part of the video that I watched.

If it is not the keyboard, long before you mess with MB, you refresh the keyboard driver in device manager. (goto device manager, HID, keyboard, delete it, then shutdown. Reboot. Windows will re-detect the keyboard and relaod driver.) Then if USB you dry different USB ports. Then you try different...

If you watched his video, and read the comments he says it's not the keyboard. It isn't plugged in.

I doubt it's the keyboard. It might be the motherboard.

Does it do this in bios? If it doesn't its most likely a software issue.
If that's the case then try running the Microsoft safety scanner. (no worries it is really from microsoft.) but do note that it expires in 10 days.

Important: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss. Also it might not catch every virus/malware.

If issue still persists try to boot your computer in safe mode and then check if it still happens.

UPDATE: I followed your advices with the "virus scanning", reinstalling the drivers, etc. Thanks for the time and effort you guys took to look into this issue. I have a theory that could be much simpler than any of this. I've backtracked the nature of the issue and it must be one of 3 things: 1. Keyboard/Mouse, USB slots and loose connections, worst of all MB problems. excluding those I completely forgot about my other peripherals I have connected. Recently I started editing with Adobe Priemire Pro and I purchased USB Switch Pedals(3 pedals) and had keys assigned to each pedal; 3 specific keys ("D" , "I" and "O"). :/ I really hope that this is causing the issue and not the MB or keyboard. Currently I've disconnected the USB Pedals and removed the software I was using to assign keys to them. I'll keep you updated.

It was the USB Switch Pedals that I bough from Amazon recently. Removed them along with their software. No problems since. I'm glad it wasn't my MB or the keyboard.
