Unwanted Computer Usage: 50Hz Refresh Rate Issue on My Lab Computer - Need Help!

AI Thread Summary
A lab computer was used without permission, leading to unauthorized changes including partitioning and installation of an unknown operating system. The user now experiences a reduced refresh rate on their Windows XP account, dropping from 60Hz to 50Hz. To resolve the issue, it is recommended to access the display settings to adjust the refresh rate. If only 50Hz is available, downloading and installing the latest drivers from the monitor manufacturer's website is advised. Alternatively, updating the existing driver through Device Manager may restore the option to select a higher refresh rate.

my computer in the lab has been used without my permission by a labmate
He told people that he knew about computer OS, he partitioned the computer discs into many rooms. There is a drive room for my Windows XP 2003 Service Park 2. He installed some OS I don't know what to call on the other free room drive. Sadly enough, he succeeded.
But now when I log into my XP account, the screen becomes darker than before (50Hertz is the rate for refresh), it was 60 before hte install, I know it!

Help me please.

Right-click on the desktop then select Properties from the dropdown menu. On the Settings tab, click the Advanced button, then the Monitor tab on the next screen. From there, you can select the refresh rate.
 
I have tried but only 50 Hz exists, I am so confused
 
In that case, you may need to download a fresh set of drivers from your monitor manufacturer's website. Or you can try refreshing the existing driver installation by going to the Control Panel > System, click the Hardware tab > Device Manager. Scroll down the list of installed devices and open the Monitors group. Right-click on the monitor and select Update Driver and follow the prompts (let Windows search for the best driver). If that fails, go download the newest driver for your monitor and install it. That should give you back the options for various refresh rates--select the highest one that your monitor supports (check the specs).

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...

Thread 'MS 365 Profile Badge colour'

Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
