Hey, so I recently upgraded my Windows 7 Ultimate to Windows 10 Pro. After the upgrade I clean installed my Windows 10 and hadn't experienced any problems. I then downloaded the appropriate drivers for my hardware and then a avast, and then steam. After it sat for about an hour or so my screen started blinking. It seems to do it whenever the system loads. I cant get around anywhere on the desktop either because when it blinks my mouse goes to the center of the screen. I tried to delete and reinstall my graphics card drivers, but it didn't work. I tried entering safe mode, but it still blinked there. I even tried resetting Windows, but still no luck. Please help.
