Question

The blue screen occurred on my laptop. I'm running Windows 7 Home Basic SP1 (32-bit).

What caused this problem and how do I fix it?

Answer 1

Something probably related to pcas.exe, which is Alipay Security Payment Client Suit( nok nok??) is causing the processor to hang, resulting in a BSOD, when an expected clock interrupt was not received on a secondary processor in an MP system within the allocated interval.

Please check with the software publisher's website to see if there are any known issues.

Note: Since this a  security related software  used for authentication  to enable secure online payments, it may be conflicting with AVAST . If it come down to it, you may have to remove it to test.

Also, please update your AVAST Security software to the latest version,  or completely uninstall it (preferred) and install Microsoft Security Essentials.
