Attempting a DIY repair can save BDT 500–2,000 in service fees, but the wrong move can turn a BDT 500 problem into a BDT 15,000 motherboard replacement. BAYAS **repairs** all major laptop brands at your home in Dhaka — certified technicians, genuine parts, and a 30-day warranty on every job. Check our [Laptop Repair](/services/laptop-repair-service-dhaka) page or WhatsApp 01712-644590 for a quote. At BAYAS, we have serviced over 5,000 computers across 36 Dhaka zones since 2018. We see the aftermath of DIY attempts every week — and also see plenty of cases where a simple at-home fix would have saved the customer time and money. This guide draws a clear line between what you can safely do yourself and what needs a technician's hands. --- ## What Is the Risk Scale for DIY Computer Repair? Before we dive into specific problems, understand this hierarchy of risk: | Risk Level | Examples | Cost of Mistake | |---|---|---| | **Low** | Software issues, cable checks, cleaning | Zero to BDT 500 | | **Medium** | RAM/SSD installation, thermal paste | BDT 500–5,000 | | **High** | Laptop screen replacement, motherboard work | BDT 5,000–25,000 | | **Critical** | Water damage, soldering, BIOS mods | BDT 10,000–50,000+ | **Rule of thumb:** If opening the device voids a warranty you still hold, or if you cannot find a YouTube teardown for your exact model, stop and call BAYAS instead. --- ## Low-Risk Problems (DIY-Friendly) These fixes are safe for anyone with basic computer knowledge. ### 1. Slow Computer — Software Causes **Symptoms:** PC boots slowly, programs lag, browser tabs stutter. **DIY fixes to try first:** 1. **Uninstall bloatware** — Go to Settings → Apps → remove programs you never installed knowingly (trial antivirus, manufacturer toolbars, etc.) 2. **Disable startup programs** — Press `Ctrl+Shift+Esc`, go to Startup tab, disable everything except your antivirus 3. **Run Disk Cleanup** — Search "Disk Cleanup" in Windows, select your C: drive, check all boxes, click OK 4. **Check for malware** — Run Windows Defender full scan or Malwarebytes free scan ![Slow PC troubleshooting in Dhaka — BAYAS guide](/images/blog/pc-problems-diy-vs-professional-dhaka.jpg) **When to call a pro:** If your PC is still slow after these steps, the issue is likely hardware-related — old HDD, insufficient RAM, or failing components. Our [computer service center in Dhaka](/contact) can diagnose this in under 30 minutes. ### 2. No Internet Connection **Symptoms:** WiFi shows connected but no internet, or WiFi network not showing at all. **DIY fixes:** - Restart your router and modem (wait 30 seconds before plugging back) - Run Windows Network Troubleshooter (right-click WiFi icon → Troubleshoot) - Forget and reconnect to the WiFi network - Update network driver from Device Manager **When to call a pro:** If other devices connect fine but your PC still won't, you may have a failing network card. BAYAS offers [home PC repair service](/services) across Dhaka and can replace WiFi cards on-site. ### 3. PC Making Unusual Noises **Symptoms:** Clicking, grinding, or loud whirring from the case. **DIY check:** Open the side panel (desktop only — do not open a laptop unless trained) and identify which fan is noisy. Clean visible dust with compressed air. **When to call a pro immediately:** A **clicking** sound from the hard drive means imminent failure. Back up your data *now* and call a technician. BAYAS offers emergency [data recovery services](/services/data-recovery-service-dhaka) if the drive fails before you can back up. --- ## Medium-Risk Problems (Proceed with Caution) ### 4. RAM or SSD Upgrade **Difficulty level:** For a full list of upgrade options and pricing, see our [Computer Upgrade Service in Dhaka](/services/computer-upgrade-service-dhaka). We also offer [Desktop Repair Service in Dhaka](/services/desktop-pc-repair-service-dhaka) for all PC issues. Easy on desktops, moderate on laptops. **Desktop RAM upgrade** is genuinely DIY-friendly: 1. Power off, unplug, press power button to discharge 2. Open side panel, locate RAM slots 3. Push clips outward, insert new RAM until clips click 4. Close and boot — your PC should detect the new RAM automatically ![RAM and SSD installation in Dhaka — BAYAS guide](/images/blog/computer-repair-dhaka-complete-guide.jpg) **Laptop upgrades are trickier.** Some models (especially ultrabooks 2019+) have RAM soldered to the motherboard. Check your model on Crucial's compatibility tool before buying anything. If in doubt, BAYAS can install your purchased RAM for a small labor fee at our computer repair center in Dhaka. **SSD upgrade:** This is the single best performance upgrade you can do. A SATA SSD takes any 2015+ PC from "unbearable" to "snappy." Cloning your old drive requires free software (Macrium Reflect, Samsung Data Migration) and a USB-to-SATA adapter. BAYAS offers full SSD upgrade service starting at BDT 1,500 including data migration. ### 5. Reapplying Thermal Paste **Why it matters:** Stock thermal paste dries out in Dhaka's heat in 12–18 months, causing CPU temperatures 10–15°C higher than normal. If your laptop fans run full speed during light use, this is likely the cause. **DIY only if you are comfortable with:** removing a cooler, cleaning old paste with isopropyl alcohol, applying the correct pea-sized drop, and remounting with even pressure. Mistakes include using too much paste (insulates instead of conducts) or overtightening screws (cracks the die). BAYAS offers an [annual repaste service](/services/computer-maintenance-service-dhaka) for BDT 1,500 at your home in Dhaka. --- ## High-Risk Problems (Always Call a Professional) ### 6. Laptop Screen ReplacementBAYAS serves [Uttara](/locations/computer-repair-uttara-dhaka), [Dhanmondi](/locations/computer-repair-dhanmondi-dhaka), [Mirpur](/locations/computer-repair-mirpur-dhaka), and all 36 Dhaka zones with same-day home service. ### 6. Laptop Screen Replacement A cracked or dead laptop screen is the #1 DIY attempt that ends badly. Why: - **Digitizer vs. display confusion** — Touchscreen models have bonded layers; separating them destroys the digitizer - **Ribbon cable damage** — The eDP cable is fragile and specific to each model - **Bezel clips break** — Plastic clips snap easily, leaving a loose assembly BAYAS replaces laptop screens across all brands and models. See our [laptop screen replacement cost in Dhaka](/blog/laptop-screen-replacement-dhaka) guide for pricing. ### 7. Water-Damaged Devices **Do NOT:** turn it on, plug it in, press any key, put it in rice (this is a myth — rice dust accelerates corrosion). **Immediate steps:** Power off, remove battery if possible, dry exterior, bring to a professional within 24 hours. BAYAS offers [emergency water damage service](/services/macbook-repair-service-dhaka) with ultrasonic cleaning for motherboards. Every hour of delay reduces recovery odds. ### 8. Motherboard or Chip-Level Repair If your PC powers on but shows no display, the issue could be a dead motherboard, failed CPU, or something as simple as a loose RAM stick. Diagnosing without equipment (multimeter, POST card, spare parts) is guesswork. BAYAS technicians carry diagnostic tools and spare components to every [home service appointment](/services/computer-home-service-dhaka). If your PC throws repeated BSODs with stop codes like `WHEA_UNCORRECTABLE_ERROR` or `UNEXPECTED_KERNEL_MODE_TRAP`, that is the classic signature of a motherboard or RAM failure and almost always belongs in this category. See our [BSOD blue screen errors guide](/blog/computer-bsod-blue-screen-dhaka) for the full stop code breakdown. ### 9. Data Recovery from Failed Drives If your drive clicks, whines, or is completely unrecognized, DIY software will not help — it may make things worse. Never run CHKDSK on a failing mechanical drive. BAYAS uses professional tools for [data recovery in Dhaka](/blog/data-recovery-cost-dhaka). --- ## What Is the BAYAS Decision Flowchart for DIY vs Professional Repair? ``` Is your PC working at all? ├── Yes, but slow │ └── Try software fixes (Section 1) first → Call if no improvement ├── Yes, but noisy │ └── Desktop: clean fans yourself → Laptop: call BAYAS └── No power / No display └── Skip DIY → Call BAYAS immediately ``` --- ## Why Do Dhaka Residents Choose BAYAS? **1.
