Hi there! You’ve posted your question in a forum that is for beginners trying to learn the basics of Photoshop. I'm moving your question to the Photoshop General Discussion forum for specialized attention to your situation.
Seems like your question would be better in an HP forum than Adobe. Photosmart is of course not an Adobe product. Have you checked the HP site for driver updates for your particular set of hardware?
You haven't been very specific; perhaps if you provide more info about specifically what you have and what you're seeing go wrong someone will be able to help you better.
I don't have a suggestion for you beyond that, but this is for others considering Windows 8: It's never good to upgrade to a brand new OS in the first weeks after its release. An OS is more than just software from the manufacturer - it involves support from hardware vendors. No matter how many preview versions the OS manufacturer has released, device driver perfection (printer, display, storage devices, motherboard) ALWAYS lags behind the OS release.
Right now apparently there are a number of known problems with Windows 8:
- With display drivers (people not getting good GPU support with ATI cards in Normal and Advanced modes, for example).
- With printer drivers.
- With storage drivers (I've heard of troubles with RAID controllers, for example).
In the professional realm there's an old adage, born from long experience: Never upgrade to a new Windows version until Service Pack 1.
With Windows 8 there is the additional consideration (for those who haven't yet taken the plunge): Carefully consider whether Windows 8 adds any return on investment (ROI) that you actually need.
Microsoft has taken off in a new non-pro direction with Windows 8 and has actually DEGRADED the desktop experience (presumably to try to herd us all over into the Metro/Modern realm). It may be that the best idea would be to continue to use Windows 7 and wait until Windows 9 (or whatever they call the next release) to re-evaluate upgrade options.
