Windows 8.1 is a different operating system, not a service pack to Windows 8. <br />
<br />
You need to make sure all drivers have been updated. Most of the drivers in my Windows 8.1 machine are new for Windows 8.1 (they are not the Windows 8 drivers). <br />
<br />
Some applications (SEP, NCP Secure Entry and a few other others) needed upgrades in order to work with Windows 8.1.<br />
<br />
If you cannot solve the problem, you may need to back up and reinstall Windows 8, do not install applications, upgrade all the drivers and then install Windows 8.1. Check for reliability, and if all is good, install applications and restore your data.

I agree with John in that if the sfc /scannow yields nothing, a re-install is really the only solution here.

Hi - I have a very new computer, Windows 8 Basic that IO upgraded to Windows 8.1 Pro - not that they're related, but a couple weeks later we received 3 bluescreens over the course of a few days. I've attached 2 of the dmp files - I was wondering if anyone can decipher where the issue is. If I run bluescreenview it references hal.dll and ntoskrnl.exe, but i'm still not sure where the problem is. Any help would be appreciated.<br />

Hi - I have a very new computer, Windows 8 Basic that IO upgraded to Windows 8.1 Pro - not that they're related, but a couple weeks later we received 3 bluescreens over the course of a few days. I've attached 2 of the dmp files - I was wondering if anyone can decipher where the issue is. If I run bluescreenview it references hal.dll and ntoskrnl.exe, but i'm still not sure where the problem is. Any help would be appreciated.

bluescreen - Windows 8.1

Windows 8 is a personal computer operating system developed by Microsoft as part of the Windows NT family of operating systems, with an emphasis on improving its user experience on tablets. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen, a new platform for developing apps with an emphasis on touchscreen input, integration with online services, support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware.

Windows 8

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
