Programs Starting As "Suspended"

I am currently running Windows 7 Home Premium on a custom rig I built for gaming, and have been running it for a few months no problem until now.

A few weeks ago after a startup I realized that any time I started to run a program, the program would not start. I would click on the application, my cursor would get the loading circle, then the program simply would not open. Shortcuts, taskbar, start menu, even trying to boot them through console would not work. The only applications I can start are McAfee, IE8, and most admin and windows tools. Anything else just wont start. I opened the task manager and saw that the programs were running as suspended, and the only way to get them to work was to right click them and hit continue.

I ran McAfee, no viruses detected. I ran Disk check and mem check, no errors detected on either. At first the problem would happen only one out of 10 or so startups, now it occurs every startup. Doing a system restore back to a point before a windows update seemed to fix it, until my system crashed after doing that and now its every startup again.

I would at all costs like a way to resolve this issue without needing a fresh reinstallation (though it seems that is the only solution), as I currently have no means to backup some important stuff I have on my computer .
