Checkerboard pattern, random freezes, screen tears, start up fan issue warnings

[Ihardy]

My laptop has become useable in the past few days. I have no idea what as triggered this. I haven't been on any risky sites, no crazy downloads, and I haven't removed anything. I've had this problem before where games would'nt play and I kept getting "blah blah has been block from acessing grahpics hardware" but that was solved by updating my drivers (for some reason they refuse to update automatically). Now it's come back with a few.... A LOT other problems. The random checkerbaord patter still pops up when typing next, the screen still tears (Imagine tossing a thin layer of black ink on your screen). The screen freezes up randomly. And when I start up the game I get this random message about my fan not working properly. I cant get a good imagine from it with  my phone. Everything is up to date. And whenever I try to upload a picture on here my laptop erases my typing so please reply wtih an email adrress. sorry for typos it gets worse the more I type

Thank you for posting on HP Forums, 

Riddle_Decipher is at your service. 

As I understand the device has multiple issues with graphics, freezing and fan errors,

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details: 

Have you attempted to perform a hard reset?

Did you run a hardware test on the device?

While you respond to that, here's what I recommend you do:

First, let's start with performing a hard reset on the PC to release any excessive static/power that could have caused the issue. 

  

Turn off the computer. 

Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers. 

Unplug the AC adapter from the computer. 

Press and hold down the Power button for about 15 seconds to drain any residual electrical charge from the capacitors that protect the memory. 

Press the Power button to turn on the computer. 

If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key. 

  

Second, you can check if there is Bios update available for your PC, here is the link to download. 

  

Performing a test on the Hard drive as well as on the Memory from the Hardware diagnostics:  

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the HP PC Hardware Diagnostics (UEFI) main menu, click System Tests.

4. Click Extensive Test.

5. Click Run once, or Loop until error.

   While the test is running, the time remaining and test result for each component are shown on the screen. The test can take 2 or more hours to complete.

   NOTE:

If the diagnostics are not available when using the F2 menu, run the HP PC Hardware Diagnostics from a USB drive. To download the latest version of the diagnostics, go to the HP Hardware Diagnostics website. For instructions, see Testing from an external USB device.

Depending on the test results, If the test passes then I would suggest you perform a complete system recovery.  

Note: Recovery will wipe off everything from the computer. If you have anything important get in touch with some local stores to get your data backed up.
