The maximum temperature for that CPU is 100c, the Speccy shows it running at 44c. The CPU is running well within normal tolerance.
Are you running strictly on battery power when this happens?
When the power adapter in plugged into the laptop does the LED indicating the adapter in plugged in go out?
Another possibility for this could be a problem with the RAM. We can check this by running Memtest86. But first remove one of the two RAM modules and try running the laptop with it in each slot to be sure it is working in both slots.
1) Please download the Memtest86
Pre-Compiled Bootable ISO file.
2) Unzip the downloaded memtest86
file. You will need a program like 7-Zip
to unzip this file.
3) Inside, you will find the memtest86 file.
5) Insert blank CD into your CD drive.
6) Open ImgBurn, and click on Write image file to disc.
7) Click on the Browse for a file... icon:
8) Locate the memtest86 file, and click on the Open button.
9) Click on the blue arrow to start burning bootable memtest86 CD.
10) Once the CD is created, boot from it, and memtest will automatically start to run.
Please note: It may be neccessary to change the boot order in the BIOS so the CD/DVD-ROM is the first device in the boot order and the hdd second.
Each pass consists of 8 tests, it is suggested that you run at least 7 passes, this will take several hours, you may find it simpler to let it run overnight. The longer you run the passes the more comprehensive the results will be.
If you are running multiple modules and have a failure, remove all but one module and test it separately, continue this with each module till you find the one that failed.
When you discern that a module is good, use it to test each slot to be sure there isn't a problem with one of them.
When the test is complete a display similar to the one below will appear. Note the locations of the Pass and Errors, any Error is indicative of a failed module.
