While running an avast quick scan this blue screen appeared:
A problem has been delected and windows has been shut down to prevent damage to your computer.DRIVER_IRQL_NOT_LESS_OR_EQUAL
If this is the first time you’ve seen this stop error screen,restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software maunfacturer for any windows updates you might need.
If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced startup options, and then select safe mode.

Beginning dump of pysical memory
The computer them restarted itself and got stuck on the first loading page at this point:
Auto-Detecting Pri Master..ATAPI CD-ROM Auto-Detecting Pri Slave..ATAPI CD-ROM
After a short while it went to a screen that sais:
Reboot and Select proper Boot device or Insert Boot Media in selected Boot drive and press a key_
I pressed the small reset button, and it got stuck on the same CD-ROM part of the boot up, and went to the same “reboot and Select…” screen.
I turned the PC off, left it a couple of minutes and switched it back on.
It loaded fine.
I scanned with HiJack This, Malware Bytes - full scan, Windows defender - full scan, Avast Boot Scan, all were clear.
I have no new hardware or software.
Has anyone seen similar behaviour during an avast scan?
What could have caused this?
Many thanks.
