HT5100 Itunes u just opens and closes immediately when I try to use it. It worked previously, and now it doesn't. I tried uninstalling it and then installing it again and it still closes as soon as I open it. Other apps do not do this. What should I do?

iTunes u closes as soon as I open it. What should I do?

I would start with this FAQ Entry first, if you have not done so yet: http://forums.adobe.com/thread/792580?tstart=0
It starts with a checklist for getting PrE set up properly, then moves into tuning up one's system and OS (you have done a lot of that already), and then goes into troubleshooting tips. Note: those tips rather work up quickly in "degree of difficulty," and DO become quite technical, but things like the "Finding Clues" link will give some tools, that might prove useful, like the use of Windows' Event Viewer to track down issues.
One of the first things to look at would be your video driver. I would go to the video card's/chip's mfgr's. Web site, and check for a later driver. Do not trust Windows, or any utility to tell you if you have the latest driver. If there is not a newer video driver, or it will not install properly on your system, be sure to check with the HP Web site, as HP, Dell, Lenovo, and some other mfgrs. will re-package video drivers to suit their specific setup.
One troubleshooting technique, that might prove useful (however, those deleted programs bother me a bit here), would be to create a System Restore Point for now (see Windows Help for doing this with your particular OS version). Then, boot to Safe Mode, and choose an older System Restore Point, from when things did work. This might take some trial-and-error, to get back far enough. Test. At the worst, you will only have lost a few minutes, as you have your new System Restore Point for now, to fall back on.
Good luck,
