Dude, a 750w PSU for $10? I'm surprised you haven't blown up yet.
For real though, the Power supply may only be able to output 750w MAX, and is probably rated for lower. It can't output enough watts or give any clean power to your system, at least that's my guess.
And I think since the flickering is getting progressively worse, that means your PSU is dying, or getting tired, or something.
The first think I'd do is get a new power supply. Even if that's somehow not the problem, it is still very much needed. Even a cheap used Antec Power supply would be better than that fire-starter you have in your PC. Since you only have a 1050, and not a 1050 TI, it doesn't need a power connector, so I'd recommend upgrading to even something like THIS. That's not the best deal, of course, just something I found real quick.
So yeah, Find a decent Corsair/EVGA/Antec/Seasonic 400wish power supply as your first step. If somehow that doesn't fix the problem, it was still a needed upgrade and worth it.
