hello, i have some problem with my laptop, about some keys stop working, which is e,r,4,5.
i remember before that i installed a voice changer program(sorry i forgot the name) and then some icons of my files changed into something like a folder thing (can't seem to put a image link here)
and that is also the time my problem with my keypads started, at first it was just e and r but after i press them hard or for a long enough time, they start to work again, and that continues to work until just a few days ago. My keys are now hard to press, i checked for some solution and tried restarting my laptop and cooling it off, it sometimes work but still hard to press those keys, and now even 4 and 5 doesn't work anymore, by the way, i already uninstalled that program about the voice changer, fearing that it change some things on my laptop, unfortunately, the icons didn't revert back to normal and i have to change them back manually and i tried running my antivirus but didn't detect anything, i am using avast if that matters, and now even with restart i can't make them work, even in safe mode they don't work, i tried uninstalling and reinstall the keyboard from device manager but didn't work as well,(the keyboard in my device manager is called standard ps/2 keyboard, just thinking if it matters as i don't really know much about tech stuff) they do sometimes work but then will stop working again after some minutes, and then if i turn off laptop and let it rest for like a whole night, and turn it back on, the keys will work for an hour or so but then will stop working again, and i will need to press them hard again so i could make them work, and also that all of this non-working keys stop working all at the same time makes me think that it really is not just a problem with my keyboard, i already cleaned my laptop and check if the dust might be the problem but it still doesn't work, i hope you can help me, even now i'm just using on screen keyboard to type this all, and it's really hard, thanks in advance.
