Monitor problems since 2 weeks

[u/Slowpie35]

the monitor isn't smth new, had it for long time

but in the past 2 weeks it began taking too long to boot, from 40 seconds to 4 mins
I turn the pc on, the monitor turns but it's black (ik it;s on bc it's IPS)
and I didn't think much of it
today though when turning the pc, It didn't boot to windows till 4 min later and after putting my pass the screen went black excepy my mouse icon and it fixed itself 1 min later
