Common problems
Blue screen or stuck starting up
Crashes and boot loops come from a failed update, a bad driver, or failing hardware. Each one has a different fix.
Signs
Blue screen with a sad face; "Preparing automatic repair" over and over; stuck on the logo; restarts by itself.
Try this first
Unplug everything except the power, keyboard, and mouse and try again. If Windows offers "Startup repair," let it run once.
What we do
We check the drive and memory, repair or roll back the update, and back up your files before any bigger fix.
