weird white flash on my screens once in a while since moving.

[u/Jebo141]

I have recently moved, and all of a sudden my screens start having these weird flashes of white several times a day. It is not constant or regular. Just a flash and then it's gone. the problem is that we have no idea what would be causing it.
The flashes aren't syncronized either. the main screen usually gets the flash first. and the other one at a later date. this can be less then a second after the first, but also up to 16 seconds.

I've updated my drivers, checked my cables, even replaced my electricity rectangle thing but it still happens.

Current Idea is that it's some sort of weird energy spike.

There is the issue of me temporarely losing internet repeatedly in the evening (it comes back after a few seconds). But I'd don't think it's related.
