Have you ever been in a sink or swim situation where it's either pony up or go homesses, naked and hungry?

My parents dying put me in that situation.
That's why I did all I did.

Got into my dad's car that he bought new about 2 years before he died.
That I automatically inherited when he died from cancer.

Moved down South

Searched for ways to legally make as much money as possible with my current skills…
That lead me to Uber and Lyft and Uber Eats. And TruGreen.

Saved up $60,000 cash…

I got myself into a $2000 a month Lindsey luxury townhouse.
Bought Ashley Furniture
Serta Bedding.
Sony Electronics
Lenovo Computer
At&t Phone and Smartphone
At&t prepaid phone service and Internet
Xfinity prepaid Tv
GE and Cuisinart and Black and Decker and Pur appliances.
Oneida dishes, glasses and silverware.
Calphalon cookware

The full collection of vaccum types from Bissel.
Libman and O-cedar mops, brooms, buckets and cleaning supplies.

Home decor from Crate and Barrel.
Clothing from JcPenney and Macy's.
Art Supplies from Hobby Lobby.

And bought two dogs and two cats.

Then joined the Episcopal Church.

I did all that because it was sink or swim.
That's the situation that my dad dying put me in.

What type of processor socket does the Lenovo IdeaCentre K300 have, and can anyone recommend a good graphics card for this computer?

I''m trying to rebuild an old 2011 Lenovo IdeaCentre K300 desktop computer. Right now I'm trying to upgrade the processor and get a good graphics card for it but I've been having trouble finding out information of the model for this computer. Lenovo does not have any information on their website or in the owner's manual and it's hard finding information about the computer online.

Added (1). As what skeptic asked, yes this is the model.

Why does one monitor repeatedly go black on me?

So we got new lenovo computers, and they come with the display port rather than vga. I bought adapters and upon hooking everything up seemed to run fine. One day talking to someone I noticed out the corner of my eye something flash on my monitor. I thought I was going insane because it happened quite a few times always while i was looking away. So i then stared at my computer for about 10 minutes to notice there's a little black line that will hop across my screen. I then replaced the VGA cable aswell as the display port adapter. It seems to work fine, but when i'm away from my computer or doing something else. I notice upon return that everything on my two screens has been moved to one screen as if the monitor in question had shut off. Forcing my split screen into one screen, then turning back on and all my stuff stays on the one monitor. No big deal for me I can just move stuff back, but it seems to happen to every lenovo i'm putting up. Is this a common issue with lenovo? Maybe its just the adapters i bought?

Will a 240HZ monitor work with any computer?

I have a Lenovo Gaming desktop and it's extremely powerful but my 60Hz monitor is my limit. Would a 240Hz monitor actually work with my computer? Will I see a smoother framerate? Or will the computer only output 60fps on the 240Hz monitor. Or will it just output what ever the game is programmed to output.
