Hello i have a blue screen with an error kbdclass.sys but I only have it while I play games. I allready tried sfc, dism scans. Did a malware scan with Microsoft Malicious Software Removal Tool. I did Memory test. All went fine nothing wrong was found. I also uninstalled HID keyboard, Standart Ps 2......drivers and rebooted the pc I also checked for updates. I dont know which program was installed last when this error started theres too many of them. I dont have a system restore point. Is there any way to fix this without reinstalling windows? I will upload a dump file later when I get back to my pc.
