My CPU is about two years old. I have had no problems with it until now. 2 problems have happened at the same time. The first is my wireless card went bad. I know how to fix that problem. The one I can't fix is the screen is flashig white light across it. I can't view what is happen on the screen anymore. The CPU seems to be working fine but the screen is showing nothing but those lights.

Re: My screen is showning flickering white lights
To confirm that indeed you laptop CPU is working normally, you can try plugging an external monitor. This will also verify that your onboard video or memory is not the issue.
Assuming you have tried the above, as to the screen flashing, it can probably be the LCD panel display. It can either be the video converter or your backlight inverter (or CCF fluorescent tube). Any of the two would require opening the display panel and component level repair. Should you not be comfortable cracking the display open and circuit analysis/diagnosis, you may need the services of a qualified professional.
Hope this give you an idea and work out for you. Good luck and post again how things turn up or if you need further information. Kind regards.

Restart your Kindle Paperwhite Many issues with your Kindle, such as a frozen screen or issues with downloading content, can be solved by restarting your device. Help for Kindle Paperwhite (5th Generation).
Press and hold the Power button for seven seconds until the Power dialog box appears, and then tap Restart.
Note: If the Power dialog box doesn't appear, press and hold the Power button for a full 40 seconds until your device restarts.
The white dots are most likely to be failed pixels in the LCD screen. When the picture elements fail, they switch to clear and what you see as white is the backlighting.
The overheating issue in laptops is generally caused by dust and fluff blocking the cooling fins and ducts or a failed cooling fan, but it could also be caused by a hung process which runs the CPU at a high processing speed. Press control (CTRL) ALT and DEL and look at the task manager and see if you can see any processes that are running constantly near or at 100% to eliminate this being the problem.
The failing display is unlikely to be related to the overheating issue.
find out if the actual display or just the back lights are flickering first .
turn on a good flashlight lay it on the face of the display when lights go out if the picture remains then it is the back lights not the display
but either way i believe you will end up replacing the display (backlights included( and probably LEDs) ) i will look at availability and feasability of this, come back with item model number and year
Turn it over on your lap or on something soft like couch or carpet. Karate it chop it on the apple logo. Start softly and keep using more force. Folks have even used a hammer to do this but I don't advise it. You can also drop it face down on carpeted floor. Your ipad is likely stunned and needs to be stunned again to return to normal.
