Windows 7 very slow upon logging in, even in safe mode
I'm running Windows 7 on a Dell Studio 1535 laptop, normal midrange laptop specs. As of last night, whenever I start Windows, it makes it to the blue login screen at a normal pace, lets me enter my credentials, and then slows to a near-halt when I press login. If I wait a few minutes, it will make it to the desktop, at which point every single thing appears to happen at a glacial pace, forever. My computer continues to act like a 386 trying to run Windows 7 until I shut it off.
