Lenovo V330-15IKB with 12GB ram, 256gb SSD HDD. Bios 62CN51WW.
Intel (r) Core (TM) i5-8250U CPU @ 1.60GHz
Windows 10 Version 1909 (OS Build 18363.1411)
System is crashing with a black screen on the laptop monitor. An external monitor connected via HDMI at the time of the crash shows a glitched screen rather than completely black. Sometimes the crash is accompanied by digital interference audio. Pics of screens at crash: Built in monitor. External monitor.
Laptop completely unresponsive - eg Num Lock key can't go on and off. A forced restart boots up a completely normal system. There are no errors showing in the Event Viewer at the time of the crash.
Laptop is out of warranty.
Crashes happen approximately every three hours.
Crashes can happen even if system is not being pushed to do anything remotely heavy.

Actions taken so far:
- Rolled back bios from version 53. Lenovo said they had a known error with 53 and the newest windows release. I rolled back to version 52, and got crashes again. Rolled back to 51 - again crashes, so I've pretty much ruled out the bios / windows clash.
- Full diagnostic system check with Lenovo utility. No obvious errors.
- Full reinstall of Windows. Vanilla windows still crashed as I was setting up the account in the same way.
- Updated all drivers to latest possible using Lenovo software.
- Downloaded WDC software which confirmed that SSD drive had the latest firmware.
- Tried various different power options both within windows and on display adapter software. Made no difference.
- Reseated internal screen cables. This doesn't make sense anyway, because the laptop acts like normal immediately after the reboot. Still, you gotta try.
