my laptops keyboard randomly stopped working yesterday while i was playing warframe(a game on steam) so i restarted my computer and it worked for about 15 mins or so then stopped again.i tried running some of the troubleshooting windows gives you but to be honest idk if it would help or exactly what i was doing but it didnt help. i ran an anti virus scan and then restarted it again it did the same thing. i restarted in safe mode and ran another scan but it happened again.
today it was working fine for awhile then stopped. i uninstalled and the reinstall warframe but i dont believe its the problem. my laptop is an alienware um i dont really remeber what model it is its about 4 years old with intel i7 processor and it has windows 7 .(after writing half of this with the on-screen keyboard it started to work again but it did the same thing yesterday and dont believe the issue is resolved) im considering just buying an external keyboard though the usb but i would prefer to resolve the problem not just cover it up.
