Well... just feel like warning the bros and sis here...
I gotten a Acer Aspire P3 because it was small and light, just nice for me to bring overseas on working trip without the hassle of lugging my Fujitsu around.
My Acer was preloaded with the Windows 8 and a intel HD 4000 graphic system. It was pretty smooth running. Then I backside ichy and update my windows to windows 8.1... and that is where my nightmare being... my graphic card ease to function... it show me the freaking Code 43 error and I try updating the driver... don't work at all... in the beginning it show me that I have the latest driver... then I uninstall my driver, then reload my driver in again. Don't work at all.
I surf the net abit on this issues and found heaps of complain in the net (slapped myself for not reading the net). Luckily the good people in Acer included two recovery disks with the P3... and I am able to 'downgrade' my system back to Windows 8 and it was working ever so fine and smoothly now.
So, my advise is... if you gotten a windows 8 device... don't upgrade it. Read the reviews and forums first... microsoft might come up with a new patch (which I seriously doubt because this issues seemed to be there forever).
