I have an ultrabook Pavilion Touchsmart 14-n020ed running win8.1
- Laptop won't boot and gives error: ‘System thread exception not handled (iaStorA.sys)’ and reboots over and over.
- Automatic recovery gives same error.
- Pressing F9, Boot from EFI file gives another error: ‘no volume label[Acpi(PZNP0A03…..’. Tried every *.EFI , which results in same error as above.
- Inserting multiple bootable DVD’s to recover gives this error: ‘Driver IRQL not less or equal (iaStorAV.sys)’
Please advice what to do. I need this laptop for my work urgently.

Welcome to the HP Forums!
I understand the notebook can not successfully boot, stating "System thread exception not handled (iaStorA.sys)". I would be happy to assist you!
When running the bootable DVD, Windows is trying to to utilize memory using IRQL (or kernel process) and the error appears when doing so. This can occur after replacing a hard drive, or any PC hardware for that matter.
Since you cannot boot into Windows, this would suggest that there is a hardware issue. I'm going to refer you to this document on Testing for Hardware Failures. This will show you how to run hardware diagnostics without booting into Windows. It will let you know what hardware is failing.
Once all the troubleshooting has been attempted, please post your results, with some more screenshots if possible.
I look forward to your reply, and I will continue to research this issue further in the meantime. Thank you for posting!

Thanks for your reply.
I ran the extensive test, but strange enough everything seems fine...?
I also ran the component tests separate, but nothing strange to find.
No hardware was replaced, it is in original state, I even never opened it.
Any others things I can try?

Since the hardware on your notebook shows as functional, I recommend following this document on when a Computer Does Not Start (Windows 😎. There will be a list of quick links at the beginning of the document. The one that contains the necessary solution will be link that says "Troubleshooting other issues with computer not starting".
If after completing the remaining steps in the document and the error still remains, please call our technical support at 1-800-474-6836. If you live outside the US/Canada Region please click the link below to get the support number for your region.
