This repair: your questions answered
My PC powers on but there is no display, what is it?
Most often memory seating or the graphics card. We bench test both separately to confirm which one it is.
Will I lose my games and files?
Usually not. A no boot fault is normally power or hardware, and where the drive is at fault we recover the data first.
Do you charge if it cannot be fixed?
No. Diagnosis is covered by our no fix, no fee promise.
How quickly can you look at it?
Many problems are fixed on the spot; some repairs need the workshop.
Why this repair is worth doing right
Guesswork on a no boot machine gets expensive quickly. A structured diagnosis finds the fault without replacing working parts.
Ordered diagnosis
We test power first, then memory, then storage and board, so nothing is replaced on a hunch.
Your data comes first
If the drive is the problem we recover what is on it before anything else is touched.
No fix, no fee
If we cannot bring it back, you do not pay.
