[SOLVED] Dell laptop suffering from random hangs; has to be manually restarted.

[CrimsonKnight98]

I have a Dell Inspiron 5559 laptop and it began suffering from random system freezes which require a physical restart. There are no crash logs and no critical system errors listed to indicate the cause of the freeze. Also, there is no way of repeating the freeze, it occurs randomly, though most commonly when playing any game.

The freezes started after an SSD was installed. I uninstalled the SSD after the freezes began and reinstalled the original HDD, though the freezes persisted.

• I've tested the temperatures, all under 30°C while under load and around 45° to 50° when idle.
• Did a system diagnostic (built in Dell hardware checker for CPU, RAM, and GPU; no issues found)
• Updated the BIOS to version 1.7.0 (latest)
• Updated the drivers.
• Ran a malware scan and did find something, though the crashes persisted after the malware was removed.
• Checked the battery health in the BIOS, came back as excellent, though it doesn't retain a charge for very long.
• I am using an official Dell 45W AC charger for the laptop.
• Used command prompt to execute sfc /scannow with no issues found

System specs:
Windows 10 Home 64Bit Build 18362
CPU: i5-6200U
GPU: Intel HD520
RAM: 16GB
HDD: Western Digital Black 7200 RPM (WDC WD10JPLX-00MBPT0)

I would suspect if all temperatures are good, that one or both of your ram is an issue, you can test both by getting a program memtest86, make a usb stick boot or boot cd from it and see if the ram could be the issue. (get it from this web site: http://www.memtest.org/#downiso

if your unable because it is your only computer and it locks up, alternatively you could try to take out 1 ram stick out of the system and see if the problem persist, if it does, swap the ram sticks around and test again, it could be just 1 stick that is bad.

the only other reason a pc would lock up is ack or poor power supply, but you did not identify make, model of your PSU, so I cannot infer any issues on this part yet.

I agree with @The Paladin run some better hardware tests first.

What did the malware scan find? Can you list the results? Would it be difficult for you to backup your important files and wipe and reload the OS?
