Recently well within the last 6 months my wife's monitor will cut off during like an electrical surge? I'm guessing

For example if we turn on the stove it'll cut off the monitor, and to get the monitor to cut back on we gotta restart the pc.

We have changed outlets. I've checked all the connections to make sure they are tight.

We have tried different monitors, and her monitor on my pc and it never had the problem

So I'm almost positive it's something inside of her pc. Any suggestions?

probaly shit power cable
switch it with your monitor
get a surge protector also

We have a surge protector, ive tried multiple protectors, also tried multiple cables

Get an Uninterruptible Power Supply.
