BSOD : hal.dll Please help

Before posting a BSOD thread, please read the instructions here: Blue Screen of Death (BSOD) Posting Instructions

To help you we need the dump files but I will give you some basic tests to run.

Can you scan for threats with your Anti Virus, then download and run Malwarebytes to scan for threats as well (works best in safe mode).



Go into the elevated command prompt (run as administrator) and type in sfc /scannow

Some hardware tests should enlighten us more because in your title you say the cause is hal.dll which is the hardware abstraction layer, basically it's a layer of code implemented in windows that isolates the rest of the operating system from hardware changes, it communicates directly with hardware.
Now hal.dll isn't the cause unless your files have been damaged upon install or through malicious attacks.

You should run Prime95 for around 2 hours to see if your CPU is failing (I recommend running this in safe mode to isolate driver issues form CPU failure)
Follow these instructions.

Hardware - Stress Test With Prime95

Stress test your GPU with Furmark, run it for around 30 minutes. (Make sure your GPU doesn't overheat)
Follow these instructions.

Video Card - Stress Test with Furmark

Test your RAM with memtest86, run it for at least 8 passes.
Follow these instructions.

RAM - Test with Memtest86+

Finally run SeaTools to see if your HDD or SSD is failing.
Follow these instructions.

I recommend downloading and running a temperature monitoring software, run it when stress testing your CPU with Prime95

I recommend HWMontior, you can download it here: HWMonitor CPUID - System & hardware benchmark, monitoring, reporting
