Since you don't have a warranty anymore troubleshooting it and getting this sucker working by yourself is your only option. is your monitor the ASUS ROG SWIFT PG258q? if so that's a monitor absolutely worth saving, but why do you think its a power issue? a faulty mainboard/scaler can do all kinda stuff. have you tried using a different power cord? (I know it sounds silly but this has caused me problems MULTIPLE times) because of your description It's obvious that it isn't a software issue or anything associated with your actual PC, but a driver update or reinstall wouldn't hurt. Who knows that might do something.
Here's a link to a listing of your mainboard:

i forgot to mention that i still can use the monitor. the only problem is when im using it it randomly shuts off the screen no display or anything the led lights are still on. I tried pressing the power button and it wont turn off i tried pressing the menu and it wont show the menus its like the monitor is randomly freezing. but thank you verymuch for the link. If theres nothing else i can do with this monitor i will buy that one.
No problem! i'm sure with a little patience on eBay you could get a better deal but 80$ is pretty good. when using your monitor, is there any other abnormal things other than a sudden absolute screen blackout and button lockup? Does it shut down more often while doing something specific? Before i buy new PCB parts i try to reflow them in my old toaster oven, for me it has been a 70% success rate but there is a small chance that you could break it worse.
Here's a link on how to do that, its the same process with all boards: https://www.youtube.com/watch?v=8Xanr4jkmEc
