- if "recently" is less than 30 days ago you can go back to Windows 7. But my guess is that this is a hardware issue, and then another OS won't help.
- If it's more than 30 days, you can make an image to go back to, and then go back from your recovery disks (back to Vista?) or from your latest Windows 7 image, to see if it's OK. If it is on your latest Windows 7 version, stay there and don't upgrade.
- Did you check that everything is fine if you run a Linux Live OS? If not, that surely points to hardware issues.
I recently upgraded to Windows 10 and I ran into a bunch of problems. Among other - smaller ones, the biggest one for me is the keyboard problem, which is similar to ghosting out in the middle of work.
I have an "older" Acer Aspire 7738G laptop. It probably reached it's peak with Windows 7, as it was originally launched with Windows Vista. It worked great on Win 7 and in the first days of the upgraded Win 10.
Now... the problem started at random. With random ghosting on the keyboard (like multiple buttons are being pressed at one and hearing the internal speaker making the "squeak" sound). Lately, the keyboard started not responding from the minute the laptop is powered on, even not loading the BIOS.
A strange symptom that occurs is that when the keyboard is "out for good" the only combination of keys that respond is the "FN + Left/Right" which triggers the brightness.
Solutions tried so far:
1. Disabling the keyboard and similar inputs from the "keyboard" category (eg. HID) from device manager is not possible. Removing them can cause the computer not to turn on!
2. I've ordered a new keyboard from eBay. Replacing the (hardware) keyboard did not solve the problem either.
3. Activating "keyboard filtering" made things worse...
Things to know:
1. I have the Windows 10 Professional 64 bit version.
2. The drivers have automatically updated themselves with the windows. Had a similar problem with the touchpad and it turned out that there was a trojan virus in the driver... somehow. Scanned everything, but no more viruses are present on the system.
