Simply shared what worked for me. The problem has been resolved and has not "reverted" back.

HI Chris thanks for the update please make sure the have a X51 first gen there so i to and other here who have one can also have it fixed. What was explained to me by PNY support is that most if not all mainstream cards instead of card made for server stuff is having this issue. 

I just went ahead into BIOS and disabled SecureBoot. The watermark is gone now. Hope I wont have any problems after doing this. So far everything is working fine.

Regards,

Have you even READ the previous posts including mine?  This DOES NOT WORK on Dells or Alienware machines.  The option to enable Secure Boot is GRAYED OUT AND UNAVAILABLE.  In addition, the steps you posted have been posted numerous times and people have replied stating the exact same thing I just told you NUMEROUS TIMES.

This post of mine actually does contain some anger and I do need to calm down now because having the same non-working instructions posted again and again and again is ENRAGING!!

I apologize to anyone sincerely trying to help with this issue for the tone of this post.

Again I ask why I need to calm down.  Actually, nothing in my last post was angry or hate-filled in the least.  Is it no longer our right as consumers to ask that the products we buy from manufacturers work as advertised.  Instead of me "calming down" maybe more consumers need to get agitated.  IF this is a video card bios issue, how would I even know?

The only behavior I have seen is that the BIOS settings for Secure Boot and OPROM either can't be changed or if they are changed, a reboot sets them back to non-changeable.  There is no message in the BIOS or in Windows detailing any issues with my video card bios.  Are you now telling me that the average consumer needs to be able to find and update their video card bios to fix an issue with Dell BIOS?  Do you actually believe that my parents who bought a Windows 8 machine six months ago are going to have to research and install a video card bios upgrade?

I'm sorry but I support the IT infrastructure at our local offices consisting of approximately 300-400 people and I don't believe that even 10% of those people are capable of diagnosing or fixing this issue.

If there is a way to find out if this is a video card issue please tell me how so that I can help my friends and family with this.  I have been googling my *** off since Thursday night and I have yet to find a way to do this.  My video card is an AMD Radeon HD 7700 and gpu-z shows nothing in there about UEFI or Secure Boot compatibility or settings.

Please explain why it's now our responsibility to "relax".  Am I wrong in understanding that all of the OEMs including Dell have had the final build of Windows 8.1 for approximately a month?

Microsoft released Win8.1 RTM to OEMs in late August - but if Win8.1 RTM was the complete/finished build, MS wouldn't have had to release General Availability Rollup KB2883200 (http://support.microsoft.com/kb/2883200) as well as the following other updates on the 17th:

Additional searching for information on the UEFI compliance of AMD video cards took me to an out-of-date forum post.  While the information is not relevant to the discussion here, this particular post caught my attention and is somewhat along the lines of what I would like to see from my Dell BIOS if there is an issue with the video card BIOS.  I am including this only for reference.

"I turned on the Super Fast Boot (or whatever ASRock calls it) in the BIOS and when it finishes the BIOS check it stops and tells me my video card is not UEFI GOP compliant."

only way to find out is like i did call AMD first thing in the morning on Monday and ask them dose this HD7700 support UEFI boot it may and it may not but can't hurt to ask them That's how i found out was just like you i can't change anything. i then started to call various support people microsoft,Dell , and last my video card manufacture who was more informed then any others and told me that most if not all are having issues because there video cards don't support secure boot, and he then went on to explain how most mainstream cards don't as they were never intended to, because UEFI is fairly new and most our not putting UEFI boot on there cards. 

What gets me is how video card manufactures have most likely known about UEFI and why they never inclined to fix this issue along time ago  know its come to bit us all in the royal A** so to speak.
