Windows støtte

Fra 399 kr

Windows should make daily life easier — not deliver blue screens, stuck updates or programs that crash without explanation. At Datorhjälp Lerum, Göteborgsvägen 3, we have over 20 years of experience troubleshooting Windows 10 and 11 methodically instead of reinstalling by default.

We read error codes, repair system files, handle problematic updates and restore stability. Many cases are resolved via /fjarrsupport the same day; for hardware or display issues we book home visits in Lerum, Floda, Gråbo, Partille, Gothenburg or Alingsås.

You learn what went wrong, what we did and whether /windows-11-installation or /langsam-dator may be the next step. Call 072-297 55 25 or book an appointment — we explain clearly without unnecessary jargon.

Windows support in Lerum — technician troubleshooting and optimising Windows 10 and 11
Help with Windows 10 and 11 in Lerum — troubleshooting, updates and blue screens.

Typical Windows problems in everyday use

Blue screen (BSOD), black screen at startup, Windows Update looping for hours or programs that stop working after a patch — these issues affect both new and old computers. Sometimes the cause is drivers, sometimes corrupted system files or incompatible software.

Many people try forum tips and end up in a worse state: wrong registry edits, deleted partitions or half-finished reinstalls. That often costs more time to fix than getting professional help from the start.

We determine whether the problem is software- or hardware-related before acting. That saves you money and reduces the risk of losing important files unnecessarily.

Systematic Windows troubleshooting

We start with logs and error codes, run system file repair (e.g. SFC and DISM), handle problematic updates and restore drivers where needed. The goal is a stable computer without unnecessary reinstall.

If the root issue is security or performance, we include /virus-borttagning or optimisation from /langsam-dator in the same visit. For ongoing instability we discuss /windows-11-installation or a clean reinstall with backup first.

After the fix we test startup, updates and the programs you use most. You receive a short summary so you can feel confident the system is ready for daily use again.

Signs you need Windows support

  • Blue screen with error code or automatic restart without warning
  • Windows Update stalls, fails repeatedly or takes days
  • Computer restarts in an update loop or freezes on the logo
  • Programs crash after a specific Windows update
  • Cannot sign in — password works but desktop does not load
  • Sound, Wi-Fi or display stopped working after an update
  • Error messages about missing DLL files or corrupted system files
  • Computer became suddenly much slower without new hardware

Common causes behind Windows trouble

  • Incorrect or outdated drivers after a major feature update
  • Corrupted Windows components or failed update packages
  • Conflict between antivirus and system services
  • Full system drive preventing updates from completing
  • Faulty RAM or hard drive causing intermittent crashes
  • Programs installing filter drivers (VPN, backup, "optimisers")
  • Improper shutdown or power loss during an update
  • 20+ years of experience
  • 5,000+ computers repaired
  • ★★★★★ on Google
  • Warranty on completed work

Slik fungerer det

  1. 01

    Describe the problem

    Call 072-297 55 25, book online or request /fjarrsupport. We ask about error codes, timing and recent changes.

  2. 02

    Diagnosis and plan

    We read logs, test updates and system files and propose a fix with a clear price.

  3. 03

    Repair

    Drivers, updates and system repairs are addressed. Related services such as /virus-borttagning are included when needed.

  4. 04

    Verification

    Restart, update test and review of your most important programs. You get advice on what to do if the problem returns.

What to expect

Simpler software issues are often resolved within 1–2 hours, sometimes faster remotely. More complex cases with update loops or recurring BSOD may need half a day and sometimes several test cycles.

We rarely recommend reinstall as the first step. If it is still needed, we plan backup and recovery together so nothing important is lost.

Why choose us for Windows support

Windows is at the core of most home PCs we service — we troubleshoot it every week, locally and remotely.

Methodical troubleshooting

We read logs and error codes instead of guessing. Reinstall is a last resort, not the first click.

Both Windows 10 and 11

Support, upgrades and advice on /windows-11-installation when hardware meets the requirements.

Fast help via remote

Many issues are resolved with /fjarrsupport — ideal if you live in Gothenburg or Partille and prefer not to transport the PC.

20+ years of experience

From the XP era to today's patches — we recognise patterns in update trouble and driver conflicts.

Clear pricing

Diagnosis from 399 SEK with a quote before more time-consuming work. See /priser for hourly rates and packages.

Before you call or book

  • Write down error codes from the blue screen if you can see them
  • Note whether the problem started after a specific update or program install
  • Do not interrupt an ongoing Windows Update by unplugging power
  • Have your Microsoft account login ready if the PC is linked to it
  • Back up important files if the computer still starts — we are happy to help if unsure

Reduce the risk of Windows problems

  • Install updates regularly but do not interrupt mid-restart
  • Keep at least 15% free on the system drive so updates can complete
  • Uninstall programs you do not use — especially old "tune-up" tools
  • Create a restore point before major changes when Windows allows it
  • Use antivirus and avoid disabling Windows Defender without a replacement

Windows 10 and the end of support

Microsoft ends security updates for Windows 10 on 14 October 2025. After that date, the risk increases that known vulnerabilities are exploited if you stay without extra protection.

We help you assess whether your PC can handle /windows-11-installation or whether you should plan new hardware. The goal is a secure, stable solution — not selling equipment you do not need.

Transparente priser

Windows diagnosis from 399 SEK. Hourly rates and fixed packages are on /priser — you always hear the cost before work expands.

Typisk tidsbruk: 30 minutes to 2 hours for common issues; complex update problems may take half a day
