De cursor beweegt niet, dus ik denk erover na om de computer uit en weer aan te zetten.

Bewegen is the infinitive, meaning to move. In this sentence, the subject is de cursor, which is third-person singular, so Dutch uses the conjugated form beweegt.

• ik beweeg = I move
• jij beweegt = you move
• de cursor beweegt = the cursor moves

So De cursor beweegt niet is the normal present-tense form.

In a simple main clause like this, niet usually comes after the conjugated verb when you are negating the whole action or situation.

So:

• De cursor beweegt niet = The cursor is not moving

This is the standard word order. Dutch often puts niet fairly late in the clause, but in a short sentence like this it ends up right after the verb.

Because dus is a coordinating conjunction here, similar to so in English. It links two main clauses:

• De cursor beweegt niet
• dus ik denk erover na om ...

After dus, the second clause keeps normal main-clause word order:

• dus ik denk ...

Compare that with daarom, which is an adverb, not a conjunction. With daarom, you would get inversion:

• De cursor beweegt niet, daarom denk ik erover na ...

So the sentence is correct as written: dus ik denk ..., not dus denk ik ...

Erover means about it or about that.

Dutch often combines er with a preposition to refer to a thing, idea, or situation:

• over = about
• er + over = erover = about it

So:

• ik denk erover na = I am thinking about it / I am considering it

English learners often want to translate word for word, but er is very normal in Dutch when a preposition refers back to a non-person thing or idea.

Because nadenken is a separable verb.

The full dictionary form is:

• nadenken = to think something over, to reflect, to consider

In a main clause, the conjugated verb moves to the second position, and the separable part goes to the end:

• Ik denk na = I think / I reflect
• Ik denk erover na = I think about it

So denk ... na is just the split form of nadenken.

Because nadenken suggests deliberate thought or consideration, not just having a thought.

Compare:

• denken = to think
• nadenken over = to think about, consider, reflect on

In this sentence, the speaker is considering a possible action, so erover nadenken is more natural than plain denken.

Also compare:

• Ik denk aan jou = I think of you
• Ik denk eraan om te bellen can mean something closer to I’m thinking of calling or sometimes I remember to call
• Ik denk erover na om te bellen = I’m considering calling

So nadenken is the best fit here.

This is a very common Dutch infinitive construction.

• om ... te + infinitive often means to do something

Here it introduces the action the speaker is considering:

• ik denk erover na om ... te zetten = I am thinking about turning ... on/off

So om introduces the infinitive clause, and te zetten is the infinitive part.

It is similar to English to, but Dutch often uses both om and te together.

Because aanzetten is also a separable verb.

With separable verbs, te goes between the prefix and the base verb:

• aanzetten → aan te zetten
• uitzetten → uit te zetten
• opstarten → op te starten

So:

• correct: aan te zetten
• incorrect: te aanzetten

This is a rule worth memorizing for separable verbs.

This is a shortened way of saying:

• uit te zetten en weer aan te zetten

Dutch often leaves out repeated material when it is easy to understand. So instead of repeating te zetten, the sentence says:

• uit en weer aan te zetten

That means:

• uitzetten = switch off
• weer aanzetten = switch on again

So the whole phrase means to turn the computer off and then on again.

The word weer means again or back, and it is very natural here because the computer is being turned back on.

Yes. That version is completely grammatical and a little more explicit.

So both are possible:

• om de computer uit en weer aan te zetten
• om de computer uit te zetten en weer aan te zetten

The version in the sentence is just more compact and natural in everyday speech.

Because Dutch usually places the object before the final verb cluster.

So the order is:

• om
• de computer
• uit en weer aan te zetten

That is normal Dutch word order for an infinitive clause. The object de computer comes before the verb parts at the end.

A useful pattern is:

• om + object + verb(s)

For example:

• om het raam open te doen
• om de computer opnieuw op te starten
• om de computer uit en weer aan te zetten
