Computer Takes Ages to Boot: Why Windows Needs Several Minutes to Start

A modern computer with an SSD should boot in 15–30 seconds: press the button, see the logo, type your password and get to work. If instead you have time to make a coffee while Windows spins its circle, and programs still won't open for a couple of minutes after the desktop appears, something is wrong. Slow startup is one of the most common reasons people call a technician — and it can almost always be fixed without buying a new computer.

The stages of a computer's startup

To see where time is lost, it helps to split startup into stages. First the motherboard firmware (BIOS or UEFI) runs: it checks the hardware and looks for a drive to boot from. Then the Windows boot loader and kernel start, and drivers and services load. After you sign in, startup programs, the desktop and background processes load. A delay can happen at any stage, and where the computer "gets stuck" often tells a technician straight away where to look.

The main culprit: the hard drive

If the computer is more than five years old and still has a traditional hard disk drive (HDD), that is most often the main bottleneck. A mechanical drive with spinning platters reads data dozens of times slower than a solid-state drive. Windows 10 and 11 are designed with SSDs in mind and boot painfully slowly from a conventional disk. Hard drives also wear out over time: slow and unreadable sectors appear, the drive starts re-reading data again and again — and startup stretches out even further.

The situation is particularly risky when startup has slowed gradually and the computer has started occasionally freezing or clicking. That can be a sign of a dying drive, and the priority then is to save your data while it can still be read.

Overloaded startup programs

Many programs add themselves to startup when installed: messengers, cloud storage clients, manufacturer utilities, updaters, torrent clients, game launchers. Each one costs a little time and memory, but together they turn startup into a long wait — especially on computers with 4–8 GB of RAM. A technician works out which programs genuinely need to run at startup and which can be launched on demand, and tidies things up without the risk of disabling something important.

Viruses, miners and adware

Malware almost always registers itself to run at startup. Hidden cryptominers load the processor and graphics card, adware embeds itself in the browser, and some viruses interfere with antivirus software and updates. If startup slowed down suddenly and at the same time you noticed strange ads, new browser extensions or constantly loud fans, the system should be checked for infection.

Windows updates

Sometimes Windows is slow to boot because of unfinished updates: on every start the system tries to install them, hits an error and rolls back the changes. This can go on for weeks. The tell-tale signs are messages such as "Getting Windows ready", "Working on updates" or "Undoing changes" at startup. These loops need careful handling, as the wrong steps can damage the system.

Drivers and peripherals

An outdated or unsuitable graphics, chipset or network driver can hold up startup by tens of seconds. Connected devices can have a similar effect: an old flash drive, a faulty external disk, a printer with a problematic driver. The computer tries to identify them and waits for a response. A technician checks the Windows event log, which records these delays, and tracks down the culprit.

Firmware settings and boot mode

The wrong boot order, fast startup switched off, a legacy compatibility mode instead of UEFI, a flat motherboard battery — all of these can add time at the very earliest stage. These settings need to be changed carefully: a mistake can leave the system unable to boot.

Symptoms that mean you shouldn't wait

• startup is noticeably slower every week;
• the computer sometimes hangs on the logo and only boots on the second try;
• you hear clicking or grinding from the case;
• messages appear about checking or repairing the disk;
• files open with errors or go missing;
• the system crashes to a blue screen during startup.

These signs often point to a storage problem, and putting off the repair is risky — you could lose photos, documents and work files.

What a technician does

1. Times each stage of startup to find where the time goes.
2. Checks the drive's health via SMART data and its read speed.
3. Reviews startup programs, services and scheduled tasks.
4. Scans the system for viruses and hidden miners.
5. Updates drivers and fixes stuck Windows updates.
6. If needed, fits an SSD and migrates the system with all your files.
7. Tunes the firmware for fast startup and checks the result.
