Frequently Asked Questions
Why does my desktop PC turn on but show no picture?
The fault could involve the display, its connection or components inside the computer. Tell us what lights, fans or alerts you see when it starts.
Can you assess a custom-built or gaming PC?
Yes. Share the component list if you know it, especially if the problem appeared after an upgrade or while running a particular game.
Can you upgrade my PC without replacing it?
We can assess compatibility and discuss which memory, storage or other changes are worthwhile for your PC and workload.
What if my PC shuts down when I play games?
Let us know how long it runs before shutting down and whether you notice heat, fan noise or an error. That helps direct the assessment.
