Hi, No, they are not the similar. “iaStorA.sys” is related to driver of “Intel Rapid Storage Technology driver” and “storahci.sys” is driver for Microsoft AHCI driver. Here I suggest you try the following steps: 1.
Open the Device Manager. Locate IDE ATA/ATAPI controllers, click and open it’s sub-menu. Right click on Standard SATA AHCI Controller and select Properties. Open the Details Tab. Then from the drop down menu, select Device Instance Path.
If any of the aforementioned fixes did not help you to fix storahci.sys error, the we recommend you to install Windows 10 one more time. If you are not sure how to do that properly, navigate to the official Window’s website and find the instructions right there.
Right click on the path and select copy and save it in some Notepad. Open Registry Editor. Navigate to following path in registry editor: HKEYLOCALMACHINE System CurrentControlSet Enum PCI Device Parameters Interrupt Management MessageSignaledInterruptProperties Note: Above AHCI controller is same string which you noted down on your notepad. And “Random Number” can vary from computer to computer.
Double click on MSISupported key and change it’s value from ‘1‘ to ‘0‘. 10 Reboot the Computer. If the issue persist, please trace the performance using the Windows performance toolkit. Then upload the.etl file to Onedrive, share the link here for analysis.
