Frequently Asked Questions

Why is my desktop PC not turning on in Dhaka?

Can BAYAS fix a dead desktop at my home in Dhaka?

Yes. BAYAS technicians carry PSU testers, POST diagnostic cards, and common spare parts to your home. Most diagnosis completes within 30 minutes. Simple fixes (reseating RAM, CMOS battery, PSU replacement) are done on the spot. Motherboard repairs go to workshop with free pickup.

Should I use a UPS with my desktop in Dhaka?

Essential in Dhaka where power cuts and voltage fluctuations are frequent. A good UPS (APC Back-UPS 1100VA) prevents 80% of PSU and motherboard failures from surges. Cost: BDT 7,000–15,000 — far cheaper than a motherboard replacement.
