Do you fix both Windows 10 and 11?

Yes. We troubleshoot both versions and help with upgrade to Windows 11 when the PC meets requirements — see /windows-11-installation.

Can you help via remote support?

Absolutely. Many update and program errors are resolved via secure /fjarrsupport without leaving home.

How much does Windows support cost?

Diagnosis from 399 SEK. More extensive repairs are quoted after assessment — see /priser for details.

Does the computer always need to be reinstalled?

No. We try to repair the system first. Reinstall is suggested only when it is safer or more cost-effective — always with a discussion about backup.

Windows Update is stuck — what should I do?

Do not shut down abruptly. Contact us and we will guide you or take over remotely. We often clear cache and reset the update service.

Can a blue screen be caused by hardware?

Yes, RAM or disk can cause BSOD. We separate software from hardware in diagnosis so you do not replace the wrong component.

Do you help with Microsoft account and sign-in?

Yes, common sign-in and account issues are part of support. We help you regain access securely.

Do you offer home visits?

Yes, in Lerum, Floda, Gråbo, Partille, Gothenburg and Alingsås. For pure software issues, remote support is often enough.

Windows-tuki

Alkaen 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.

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.

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.
