Online videos play choppy. It's getting worse, and I don't know how to fix it.

OK.  I ran the spyware scan, and it came back clean

Give us a general picture of what is on your "D" drive? truenorth

[Starbreeze]

OK.  On my D drive I have 10 folders that I have no idea what they are, but this is what they're called...


cmdcons
I386
OutputFolder
PRELOAD
sys
hp
MiniNT

RECOVERY
TOOLS


That's all that's on the D drive

I know you said "updated drivers". Video drivers (specifically) updated?

[Starbreeze]

I updated every driver that had an update available, which took forever, btw

Did you get them from the HP website? Here?

Have you tried uninstalling/reinstalling flash?

[Raptor]

I'm not familiar with that piece of software you used to list all the installed programs but why does it mention device discovery and help and support?

That's not an installed program and you shouldn't be able to see those from add/remove software. If you can see them in the list there, it's most likely adware masquerading as a legitimate program.

There are also some entries like Veoh web Player which may interfere with the operation of Flash if they're browser based plug-ins.

Did you try running Firefox with only Flash enabled and nothing else?

[Raptor]

With what did you run a spyware scan?

[Linux711]

Here is an idea. Open up a video that lags and then pause it. Open taskmanager and go to the performance tab and then play the video. What is the percentage of CPU usage?

This troubles me and sends up a red flag...
Driver updates should NOT take long to load.

[Starbreeze]

I have uninstalled and reinstalled flash. 

I have scanned my computer with several different scanners,  Microsoft Security Essentials, super anti spyware, spybot, Avira, etc.

veoh player is installed, but I rarely use it, so it's never running. 

Yes, I have run firefox with just flash.

CPU is at 100%

[JJ 3000]

Microsoft Security Essentials, Avira


CPU is at 100%

Having more than one antivirus running on your computer can be just as bad, if not worse than none at all. You should only have one antivirus running resident. Uninstall one of those programs.

Did you get those drivers from your computer manufacturer's website?

Try doing a clean boot to see if a background program is causing this problem. See here:

veoh player is installed, but I rarely use it, so it's never running. 

Isn't Veoh Player a plug-in?

You should cut down to just Microsoft Security Essentials, by the way. The rest has become irrelevant with this superior piece of software.

Did you disable everything from the add-on menu in Firefox?

[Raptor]

You know, I still find these entries a bit weird.

You should verify that they're not adware or programs that interfer with the operation of your browser. Use a search machine for that.

• Security Task Manager 1.7h
• WebReg
• Toolbox
• Status
• PS2
• KBD
• ieSpell
• Eusing Free Registry Cleaner
• F4400
• DeviceDiscovery
• Destinations
• Copy
• BufferChm
• alightedcmasth.zip
• Actiontec Gateway

Like I said before, I'm not sure what this program does that you used to list these programs but "copy" is not a windows program that should be listed. Neither is "DeviceDiscovery".

CPU is at 100%

Ok, first off I think you should remove some of those extra anti-virus programs like everyone suggested. So is the CPU only at 100% while watching a video or not? If it is only during the video, then the most likely problem is a insufficient graphics card (because the computer is forced to render the video with the CPU instead of the graphics card). What is your graphics card?
