Hello,
I've had an increasingly troublesome problem with my PC over the last week or so. What started as a slight rattling noise and slow-ish booting became periodic blue screens, and now my PC isn't able to boot at all; when I try to boot into Safe Mode, the process hangs at \drivers\CLASSPNP.SYS. My OS is Windows 7. Here's the sequence of events:
1) A couple of weeks ago I begin noticing a rattling sound coming from the PC. It sounds like the sound is coming from the front case fan but I'm not sure. No real problems besides perhaps somewhat slow boot up time.
2) A couple of days ago, I get a BSOD while alt-tabbing to a full-screen game. (Steam version of FF9, so nothing very graphics-intensive). The message says "SYSTEM_SERVICE_EXCEPTION" and it specifies "nvlddmkm.sys" as the problem. I look it up and it seems like a GPU problem. I update my NVIDIA drivers.
3) Today, I turn on the PC to notice I have no internet through my wired connection. Other devices on the network have no issues. Ethernet cable shows green LED on both ends. Also Network and Sharing Center will not open, so I'm thinking I have some kind of malware. (I didn't think to check device manager). I ran Malwarebytes, which found nothing. I also ran chkdsk /f from command prompt, and told it to run on next boot. I restarted the computer and stepped away for about 30 minutes.
I came back to a slight smell of something burning (!!) and another BSOD. This one says "DRIVER_POWER_STATE_FAILURE". The air coming out of the top of the PC case is extremely warm. I immediately shut down the computer and let it sit for 30 minutes to cool down. Unfortunately I do not have an IR thermometer so I can't tell exactly what is overheating.
I restart the computer, and I hear a pretty loud rattling/whirring sound that is pretty clearly coming from my CPU cooling system (Corsair H50 Liquid CPU Cooler). The PC is able to get to the point where I have boot options, and I choose Safe Mode. It freezes on \drivers\CLASSPNP.SYS, and that's as far as I can get.
So... where should I begin? Is my CPU fried? Is my motherboard fried? I'm not sure what I should do to diagnose further. Any help is appreciated.
