Windows 7: Win 7 won't boot past Starting Windows, or CLASSPNP

Windows 7 32bit
Win 7 won't boot past Starting Windows, or CLASSPNP

I'll try to make this very short...

I cleaned my keyboard about a week ago by vacuuming it, and wiping it down with some baby wipes. After that I've been having a lot of issues... My main issue is that my computer has gradually been taking longer to boot up, and now it's getting stuck at Starting Windows screen.

When it WAS booting, it would get stuck at installing updates after shutting down, or sometimes wouldn't let me open my control panel to do a system restore. I've ran my virus software and I got some tracking cookies that were deleted (which I believe to have been from sites I had open streaming videos while it ran.) It was taking about 10-20 minutes to boot to the login screen alone, then about 5-10 minutes to get to my actual desktop.

Currently, my PC isn't booting past the Starting Windows screen. I've tried multiple things like spamming F8 to run in safe mode, repair my computer, safe mode with networking, and currently trying safe mode with command prompt. When starting in safe mode it gets stuck at CLASSPNP.SYS and takes about 10 minutes to load into safe mode. I've read that when starting in safe mode with command prompt, and entering "rstrui.exe" opens the System Restore option. Currently, I've been sitting here for about 10 minutes until it finally loaded, and sitting here for an additional 10 minutes as it "loads".

My computer came pre-installed with Windows 7, and I want to do a factory condition restore to get it back. I don't mind losing all my files as I don't have anything truly important. Just about 50-70 games from Steam I don't even really play that I'd just have to re-install, and a couple images I could grab from e-mails. My parents have a Windows 7 install disc I'm sure from their HP they bought a year or so ago, but I don't see how that would help me as I don't know the specific serial key for my Windows copy, as it was pre-installed.

Forgot to mention I tried the run from last known good config option and it just sat at the windows starting screen as well. Halp pl0x ;___;

*Edit - I lied, I found a disc copy of Windows 7, and I'M GLAD I didn't do a factory restore. I forgot I had ONE item I truly want that I would've been upset to lose. My text copy of item sales/profits on Steam.

Work through the steps for Troubleshooting Windows 7 Failure to Boot including the hardware tests since you might have gotten a static burst from vacuum.

You can test if the OS and /or Hard drive are responsible and thereby clear the rest of the hardware by running for awhile with a boot disk like Peppermint3 - Create Live CD/DVD/USB To Use For Emergency Backup - Windows 7 Forums If it still bogs then disable the HD in BIOS setup to see if it clears up.
