Blank screen after using autoruns

I used autoruns to uncheck some duplicate and unneeded processes, and apparently I also unchecked something that was needed, because it could not restart. I did startup repair, and after it said it was "preparing" several things (desktop, etc.) the screen was medium-blue and blank. I did system restore, but it didn't fix the problem. I'm guessing that's because I just unchecked something, so nothing was actually deleted? Anyway, the only way I can use it now is in safe mode with networking. It doesn't load explorer.exe properly, and I don't know if my profile got corrupted. It doesn't show any location for my profile, or logon script for me. I have a 10-year-old HP Pavillion with 1G of RAM. I can't provide the whole system particulars, because I can't get to them. I tried to find a way to use autoruns from online, but it only gives me the choice to download, and I can't get to where it downloads because I can't access Windows Explorer. Is there any way to recover from this without starting over with a fresh install? I hate to go through all that if there is any way around it.

My suggestion is:
Boot on Safe Mode
Open control panel - Users accounts and create another admin user as TEST. Restart
On next boot log in as Text and see if it runs normally and report back to us.

I can't get to Control Panel, I get the "Windows cannot access the specified device, path or file. You may not have the appropriate permissions to access the item." error message, although I have full permissions. I tried running system restore again from the original disk, but it says it couldn't complete because of a problem extracting a file, and then it cites a recipe file from the internet I saved in a documents folder, no idea why. I tried deleting it, but that didn't help, even though the file is no longer on the computer, it still named it as being the file it couldn't extract.

You could reinstall with an ISO from Microsoft Windows and Office ISO Download Tool
Download the tool, run it, choose Win 7, choose Win 7 HP OEM.
Burn a DVD or install it on a USB Flash disk with Rufus - Create bootable USB drives the easy way
Do a Repair Install
Use the COA key to activate.
For the updates MS releases SP2 for Windows 7

Or from the start-up repair option,
try Last Known good
Advanced Boot Options

I tried "last known good". Also, I can't get to where my files download, as I can't access Windows Explorer.
