Freezes after running about 4 hours. Must hardboot to get working again.

It almost certainly needs a new thermistor, which is the electronic thermostat sensor.

I've had a pretty good success rate with freezing drives to recover data from a dying/dead drive. Much simpler and cheaper then most other methods of data recovery.
Freezing the drive shrinks everything inside, sometimes freeing up stuck/seized/trapped components, or keeping an overheating component from shutting the drive down right away.
Stick the drive in a ziplock bag(to seal out moisture) in the freezer.
While it's freezing, set everything up to quickly transfer your files off the drive if it does work. After a couple hours in the freezer, plug the drive in and see what it does. It may only work for a few minutes, for hours, or weeks. Pull your data off as fast as you can, if it stops again, re-freeze it and start where you left off. I've frozen drives 3-4 times to get everything off.

The freezer fan motor is running slow, replace this part, this is a common fault

check the evaporator how much frost build up. if it build up block air way. the heat element or defrost thermostat is bad . otherway check the condensor make sure clean

Maybe you did not download Chrome directly from Google?
Download the free version of Malwarebytes (Anti-Malware) from https://www.malwarebytes.com/ and install it; then run it (takes an hour or more) to see if it can locate and deal with any malware in your computer. Then uninstall Chrome, reboot. Finally go to https://www.google.com/chrome/ and download genuine Chrome again. Install it, run it. Le's hope it works this time!

rotate the defrost heater timer until it clicks and see if the defrost heater is working

you need do some thing follow:
1) clean the cpu fan and sink(around there dirdy)
2) check the cpu fan is running and stop ok when power on if running go next
3) check the cpu fan, is there any running and stop then see it run again before the laptop freezen?
4) if the fan not running again before freezen that your fan control circuit out of work on the motherboard need to repair
5) if the fan running control ok that the fan can run and stop and run again. you have to add a EXT cooling base under the laptop
hope to help you solve it

there is a length of line that runs thru the refrigerator, If it drops below frezing where this is located the line will freeze causing a blockage.

sounds like its freezing up on you. check the drain outlet and make sure that its clear. also i would replace the defrost timer on this unit because its suppose to bring on the heaterfs to melyt the ice so thaat yoiu don't have to. they are around 30 mdollars at the appliancew repair store and all you need is the model number and serial number for the uit. after you get it it's either on the very top of the refrigerator section or in the very back. It has 4 wires going to it. good luck.

check the condenser at the bottom part from the front grill. could clogged with dirt. remove the dirt and check the compressor and condenser fan at the back side if they are running. it should be running.

if the compressor is very hot, un plug it for 4 hours and test it again. put the cover back at the back side if you would test it again.

tnx 4 using fixya,
