Today my laptop won't get past the Acer logo. It stalls there for a few minutes, then switchs to the window stop code blue screen, then restarts and repeats. Sometimes it tries to go into repair mode but immediately then goes to the blue screen instead. I cant acces bios with f2. The error on the blue screen is ACPI BIOS ERROR. Nothing is connected to the laptop. I realise this could be hardware or software. What are my options for trying to identify the issue and repair? Thanks.
