Problems after computer sleeps.

Question

About a week ago I started having the following problems whenever I would wake my computer up after sleep.
-Flash videos stop playing correctly, the video becomes extremely slow and jerky, beyond what's watchable. I tried watching flash using Firefox, Google Chrome, and Safari, and it was the same for all three.
-All audio stops completely, through both the internal audio card and my external Sennheiser USB audio card.
-Itunes stops functioning. When I click a song, it doesn't start scrolling as if it's playing but there's no audio, it just sits there.
-Programs that I have run many times before start giving me the pop-up dialog saying that the program has been downloaded from the internet and asks me if I'm sure I want to open it.
-Dual-monitor issue. Previously, whenever I would open up a new window for any program, it would open the window in the last monitor to have a window from that program, now it always opens the windows in the same monitor regardless.
The only thing that temporarily fixes these problems is to restart my computer, but whenever it goes to sleep and wakes up again they're all back. I've tried dumping both my local user cache and the global cache (Library -> Caches) but that hasn't fixed anything.

HI and Welcome to Apple Discussions...
Try Resetting the PRAM
Boot from your install disc, run Disk Utility to check the startup disc for errors.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
Flash videos stop playing correctly, the video becomes extremely slow and jerky, beyond what's watchable. I tried watching flash using Firefox, Google Chrome, and Safari, and it was the same for all three.
Uninstall then reinstall a fresh copy of the Flash Player plugin. Yours may be outdated.
Uninstall Flash
Install Flash
For Safari...
From the Safari Menu Bar, click Safari / Empty Cache. When you are done with that...
From the Safari Menu Bar, click Safari / Reset Safari. Select the top 5 buttons and click Reset.
Go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
Since you are running Snow Leopard, make sure Safari is opening in 32-bit mode, not 64. Right or control click the Safari icon in the Applications folder, then click: Get Info In the Get Info window click the black disclosure triangle next to General so it faces down. Select 32 bit mode. Also, (in that same window) make sure Safari is NOT running in Rosetta.


Web pages now include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. These icons take up disk space and slow Safari down. It is possible to erase the icons from your computer and start fresh. *To delete Safari's icon cache using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*
