A computer that won't start feels like the end of the world, but it usually isn't. Let's find out what's actually going on.
Black screens, endless spinning circles, blue screens with sad faces, or a power button that does absolutely nothing. Frightening, yes. Final, usually not. In my experience, most machines that "won't turn on" are suffering from something specific and findable: a failed power supply, a dying drive, a corrupted Windows installation, or one misbehaving component dragging everything else down.
I'll work through it methodically and find the real cause, not just the first plausible one. Then you get an honest answer. If it's worth fixing, I'll tell you what it costs before I start. If it isn't, I'll say that too, and help you move on sensibly instead of pouring money into a machine that's done.
Worried about your files? That's almost always the first question, and it's a fair one. In many cases the data is perfectly healthy even when the computer around it isn't. Bring it in through a drop-off and I'll treat your machine, and everything on it, with proper care.
Fill out the drop-off form, get the machine to me, and you'll have a straight answer soon after.
