I have a PC system with a really strange issue, I think it's hardware. While typing, at random moments and usually after repetitive strikes of any key, or fast typewriting, it repeats the last keystroke 15 times. For example, writing the word test, it stacks at
s letter and types
tesssssssssssssss. It is happening only using the keyboard and always but always, repeats 15 times.
None of the following helped:
- Changed keyboards. Three different brands of keyboards, USB keyboards, PS2 Keyboards.
- Removed every USB device even on-board using only PS2 keyboard.
- Changed all internal hardware except motherboard, hard disk drives and the box.
- Installed four different Windows versions, Windos 7 x64, Windows 7 x86, Windows Vista x86 and Windows XP x86.
I have also noticed, the issue is more frequent when working with two monitors. Plus every time that going to happen, stops for a second and then do the repetition.
Any idea what is this can be, or how to fix it?
