Try a different power cable or monitor if you see no display. Listen for beep codes — they indicate specific hardware faults. If the system powers on but shows no display, reseat the RAM and GPU. Still stuck? BAYAS offers same-day computer home service in Dhaka — our technician will diagnose and fix the issue at your doorstep. Is it cheaper to repair a computer or buy a new one in Dhaka? For computers under 5 years old, repair is almost always cheaper — especially if the issue is a single component (RAM, SSD, PSU, or even a motherboard). A repair typically costs 500–5,000 BDT depending on the part, while a new equivalent desktop costs 30,000+ BDT. BAYAS provides free diagnostics on WhatsApp so you can decide without any commitment. How do I know if a computer repair shop is trustworthy in Dhaka? Look for shops that provide written estimates before work begins, use genuine parts with retail packaging, offer a written warranty (30 days is standard), and are transparent about their pricing. BAYAS publishes all pricing online, shares quotes on WhatsApp before any work, uses only genuine parts, and provides a 30-day written warranty on every repair. Can computer viruses spread through external hard drives? Yes — external drives, USB flash drives, and even smartphones can carry malware. Always scan external media with Windows Defender or a trusted antivirus before opening files. Autorun viruses are common. If your computer is already infected, BAYAS provides on-site virus removal in Dhaka — our technicians clean infections, restore system settings, and set up ongoing protection. ## Need help now?
