|This is mostly a repost and I apologize. My suspicion originally was that my graphics card was causing the problems but after removing it the problems still persist.|
Okay, so I'm pretty much a beginner at this kind of thing, so if I've missed any info, please let me know.
My computer has been having a lot of issues recently, and I've tried about everything.
The main problem has three parts that happen simultaneously. The CPU fan starts whirring unusually, the PS/2 keyboard stops working, and the CPU starts spiking during simple activities like browsing a webpage.
These problems generally start at three different times. Often, this starts right when the computer boots up, usually during the windows loading screen. Otherwise it starts either after the computer has been on for an extended period of time or shortly after I have exited a graphically-demanding game.
A few other problems that may or may not be connected. Often, when the computer first boots up, before the HP blue loading screen, everything remains black until I press a key on the keyboard. Also, if the computer boots up when the fans are making any noise, it gives the error "CPU Fan Error. Computer will shut down shortly. Service PC immediately." The fan is still running during all this. Additionally, if I tell the computer to restart itself, it generally stops at the final black screen until I manually shut it down. If I tell the computer to shut down, it does that just fine.
I have tried a new CPU fan, but the problem still persists. I have installed all the latest BIOS updates. I have reset my computer to it's factory settings. I've run all sorts of hardware diagnostics, but according to those, everything is running fine.
Recently, I've been trying to remove hardware to see if I can single out the problem. Like I said, I tried switching the CPU fan, and I've tried running the computer without my added external graphics card. The problem still persists. I'm running out of ideas. My suspicion is now that the motherboard may be on the fritz.
If anyone could shed any light on this issue, I would be very grateful. I don't want to buy a new motherboard only to find out it wasn't the problem. Is there a way to conclusively figure that out?
I've included as much information as I can at the bottom of this, but again, I'm relatively new with this stuff so if I've missed something please let me know. Any ideas?
