[SOLVED] Games barely run or crash on startup

[Rhyan Minshall]

So here are my stats:
Intel Core I5 -4590 @ 3.30 GHz
Nvidia GTX 1060 3GB
8GB DDR3 RAM
Win 10 x64

So a while back I had this problem and today i decided to see if anyone here has the solution, My PC which is supposedly very high power and should be able to run most if not all games is struggling.
If I try to open a game most of the time it will crash on start up, If not its likely to be laggy. Some games once crashed give me a error saying things like "memory error" "not enough memory allocated" or "Virtual memory error"
A while back there was a problem with my RAM stick and we had to take it out and it might have gotten knocked about in the process.

Some additional facts that may help bring light to the problem include:
-The text looks weird on programs like chrome, e.g. some letters are thick and some aren't.
-Premier Pro CC couldn't find my GPU when in use and crashed frequently (Dunno if that helps at all).
-Latest game ready driver installed.
-My background was set to default windows background but most of the time is just pitch black
Any help is appreciated. Thank you.

Look in Reliability History for error codes and warnings that occur just before or at the time of the crashes.

Has the PC ever been opened for cleaning and maintenance? If not open the case, clean, then reseat all cards, cables, jumpers, and RAM to ensure that all are fully and firmly in place.

What PSU is installed: make, model, wattage, age, condition?

A mix of varying problems and errors is a sign that the PSU may not longer be up to the power demands of the PC.

I would start by testing your RAM using MemTest https://www.memtest86.com/
