Yesterday I allowed Windows Update to install whatever it was nagging me about, this was about 6am I think. After the restart so it could finish the installations I found that it took ages to boot back into Windows, at which point launching and using any program is sluggish to the point of nearly being unusable. A window slowly fades in, takes about four seconds. Firefox, which I'm using now, takes just as long to open a tab, and typing is delayed just enough that I have to wait for the sentence to catch up. Also, Yahoo has become my default search engine, I don't know if this is directly related but it's suspicious anyway. I work in Photoshop which is absolutely impossible at this point. I tried restoring back to September 5th, which reportedly succeeded, but has made no change. I wrote down the boot process this morning as it slogged past:
-7:35: Digits pop up on a black screen 98 B4 99 92 99 A2 A3 A2 A3 (seem to be the same numbers that appear, though not this slowly) It takes a few minutes to go through all of them, then it sits on A3 until-
-7:55 Goes black. Some time after this, maybe a minute or so, the 'MSI Military Class II' logo slowly, slowly loads in chunks from the top, this takes about 30 seconds.
-8:01: Logo slowly fades to black, about 10 seconds.
-8:06: A blinking prompt appears, disappears after a few minutes, reappears
-8:12: Goes black.
-8:46: Login finally appears, I'd checked on 'No GUI' in the boot options so this is actually faster than before. Can log in just fine, Windows comes up fairly promptly.
So, I don't know. Is this an infection, a driver conflict, failing hardware? I'd like to blame Windows Update but I doubt it's that easy. I have a Window 8 upgrade that I was going to go ahead and try but my external DVD drive is no longer recognized, though it works on my old laptop.
