Computer not understandable

[SomeGuyInThePark]

So this just happened recently about 8 days ago. My computer was working perfectly normal the night before but when I woke up it started to perform really poorly. It took about 5 minutes before it actually gets to the lock screen. All is says is arrows, X's, underlines, circles, dashes etc.

I really don't have the money and skill to buy/create a new pc so please don't suggest this kind of stuff.I would post a picture but it says it was to large, also I am doing this from a mobile device

Need info on the make/model of this computer. Also if its a laptop do you have a USB desktop keyboard to plug into it and see if that helps. I am guessing your trying to type in password and that is where your seeing symbol characters?

I'm sorry but I do not know it was a hand me down from my family, and yes it says gbberish on the password and start up screen.

I am seeing characters like < [] the restore button dots half circles etc.

Not enough info to help, other than if the computer came with system recovery media it would be best to wipe it clean and install fresh Windows install.

Im sorry that the answer I posted here is very vague, but with no information about the computer, I can only state a general response to your situation.

On the computer there should be a make such as HP, Dell, Toshiba, Samsung, etc

Then there should be a label on it with model #

This info would be helpful to see what you have. Additionally I have seen systems with bad motherboards show these characters on a black screen before windows boots with a corrupt BIOS etc.

Right now I could only guess what the problem is because not enough info.

Graphics Card or Integrated Graphics failure is another cause.

I am really dumb with my words. But the computer is a inspiron 20 model 3048. I may have said that I got this through family/Hand me down, but I am in a family of 6 being the youngest.

A very modern Dell all-in-one.
