Laptop keyboard stops after clicking Alt+Tab several times.

[Annoye]

So i'm playing a game in fullscreen which requires to alt+tab to go in other window or so. And after clicking alt+tab 3 or 4 times my whole keyboard stops and i need to restart my laptop. But the keyboard also stops after playing some hours and needs restart again. Any solutions how i can make my keyboard stops not working?

My laptop specs:
Acer Aspire | V5
Processor - Intel Core i5-337U CPU @ 1.80 GHz
RAM - 6 GB (5.80 usable)
64-bit OS, 64-based processor
Graphics card: NVIDIA GT 620M
OS = Windows 8

Try this...

1. Uninstall the keyboard driver.
2. Reboot the computer (without reinstalling the driver).
3. When it restarts, it should reinstall the driver on its own.

If this doesn't work, you may wish to try connecting an external keyboard and see if it works fine. If it does, then it could be the keys themselves that are the issue.

You may also want to try updating the Synaptics Driver if the above doesn't help.
