Windows 7 Takes Several Minutes To Wake Up

I will first say I have searched the internet far and wide and have not found a solution that has worked yet. Secondly, this is a home build that is nearly a year old with no issues to this point so it's not connected to so-and-so PC supplier who released a driver update that I know of.About a week ago, my computer has decided to take its time when waking up from sleep. It is Windows 7 Professional, completely updated with no problems to that point. When it falls asleep and I wake it up, the machine starts up and is active, but my monitors, external hard drive, and other peripherals are never turned on as they once were and the machine just sits there running with a black screen. After exactly 1 minute and 50 seconds, the hard drive, monitors, mouse, keyboard light up and I'm good to go. It was about 10 seconds prior to whatever it is that happened. I have tried turning off hybrid sleep. I have tried using hibernation instead of sleep. Same error. I found online where someone said they had this problem with an ATI card, but once they upgraded the Catalyst Control Center and drivers, they had no problems. That did no good. The only update I've done recently is Firefox, but I have not seen any other reports of the newest Firefox causing sleep problems. I read where someone had a problem with waking up from sleep mode because of Firefox's memory leaks and they said closing Firefox before putting it to sleep helped.I upgraded to SP1 after that and it didn't correct anything.It does not matter if I put it to sleep and wake it up immediately or if it goes to sleep and when I get home from work, boot it up. The same thing happens no matter the length of time.

I have a dual boot with Ubuntu, but that has been on there for months with no errors and Ubuntu will sleep and wake up just fine, usually; sleep has never worked correctly for it. There have been no hardware changes or any hardware driver changes other than the video card. I tried rolling back video card drivers to see if there was a difference with no change. My ASRock MB has the most up to date BIOS that has been out for over a year. My video card is a 5770, but like I said, I've tried older and new drivers. I tried the prevx black screen fix with no luck. I saw the Windows hotfix for this problem, but no where did they provide a link to this hotfix so I'm assuming it was downloaded in an update at some point so it is doing no good for me.
