Win7- slow boot, then black screen safe mode hangs on classpnp.sys
Hey,
I'm no stranger to troubleshooting necessarily, but as I'm worried this is a hardware issue, I come to ask for help. I'm a (very) long time lurker of this forum. Sorry for asking for your time to help me out!
We recently moved and his pc, the one that is now not functioning well, runs Windows 7 64bit. It's a custombuilt pc and has always worked like a charm, according to him. But because of the move, the pc may have dropped a bit, it thumped on the ground, so hence my reasoning this may actually just be a hardware issue, particularly because classpnp.sys problems seem related to hardware problems.
So in short - when you turn on the pc, the boot takes about 5 minutes. You get to the windows screen, it then turns in a black screen, then the desktop loads. It used to take 10 seconds, seeing as it's on a SSD.
So my reasoning was to do this -
1. Sort out updates. He never updates. 71 non-essential updates. This took extremely long, so I stopped to check out other venues first:
2. Check for malware. Nothing.
3. Check what's booting with ccleaner and what is currently running. Nothing weird or unnecessary, not even an antivirus.
4. Check system restore so I can maybe just go back in time and fix it this way. Mm, it doesn't load. AT ALL. Stuck on "preparing this may take some minutes".
5. PC in general seems a bit sluggish to my taste, but he assures me it is "working as always" once in Windows.
6. Go safemode to see if the slow boot happens there.
Aaand I CANNOT get into safe mode (w/o network). It hangs on classpnp.sys. Now I've read a couple of things 1) it's a bug in windows that you can hotfix. 2) from other forums, it seems also related to update problems, so should try system restore, but as I can't access that it's a bit rough, 3) it's related to hardware issues.
Now I've never accessed his safe mode before, so it could be that he always had a classpnp issue and we never knew.
I'm probably gonna end up doing a clean reinstall of Windows, but until then I'd like to see what you guys think. I'm going to go ahead and finish the unessential updates (and I will also reinstall his gpu drivers), I'm of a mind to try the hotfix because why not, and I'm gonna check his boot log just in case something else comes up.
Thanks for any input. Sorry for the long read.
