What happens when your computer displays a blue screen of death?
I've seen posts all over the Internet that tell you about all the different internal errors that can cause a BSoD, that say how to decipher what all the code means, and all kinds of stuff like that.
But what actually happens inside the box? Like... physically, does anything turn off?
I'm asking because a few days ago, I was turning off my computer, and right before it turned off, I heard a distinct noise that I now know is my hard drive slowing down and stopping, which of course usually happens right after the computer turns off. Realizing that something wasn't right, I turned the monitor back on just in time to see a blue screen of death.
So... does your hard drive always turn off when you get a BSoD? Or is my hard drive not working right? Because last time I checked, it was my graphics card about to go bad, not my hard drive....
I can't really just buy a new one though, because it's not that old and I don't have that kind of money. I will only replace it if I am 110% sure it's gone bad. For all I know, what happened was completely normal and I only happened to notice it this time.
If I had to make a guess why the BSoD came up, I would say it's because the fan on my graphics card is going bad and it suddenly stopped making its weird, abnormal noise and just acted normal for once. Maybe it was messing up and caused an error. I mean, it hasn't happened again, and I've turned it on and off quite a few times since. But I'm just worried it might mean something bad for the future. Is your hard drive supposed to stop spinning when the BSoD comes up??
I know I don't have any viruses because McAfee just scanned it not too long ago. I actually had my computer unprotected for almost three years before I put McAfee on it, and how many viruses did it find? Three. How many of them did I know exactly what they were and knew they weren't anything bad? Three. So I know a virus didn't do anything. Anyways, my problem isn't so much why the BSoD happened, because I know every once in a while things like that happen, and I'm not worried about it because it hasn't happened again yet. I was worried that my hard drive turned off before the rest of the computer. But one of you said that does happen, which makes me feel a lot better, thanks!

BSoD is caused by a program doing something it shouldn't, and the operating system being unable to recover from it. In some cases, the BSoD is caused by the operating system itself, or a low-level program like a device driver.
The BSoD itself won't cause things inside your computer to turn off (like your hard drive) but if left alone, the hard drive could still power itself down due to inactivity but that doesn't sound like what happened here.
Probably what happened is that Windows sent the command to the hard drive to make sure it's gotten all its data written out of the cache, and then to shut down when the BSoD hit. This would have prevented the rest of the shutdown process, but still allowed your hard drive turn itself off, thinking the rest of the computer had also shut down successfully.
Modern hard drives come with some diagnostic systems that can communicate with your OS (Windows) in case they're starting to experience failures. You can see if there are any problems like this by opening the Device Manager, and then looking at the properties for the hard drive(s) in question.

BSoD typically relates to a fatal error, which in the instance of it happening, your computer wants to stop all possibilities of your computer being harmed further. So in this process it spits out the coding and stops your hard drive to prevent any more damage. The idea that a video card made this happen doesn't seem right, something like this can happen from something as simple as changing a system file (which can be done by a virus).
No need to get a new computer, try just getting a new hard drive if the BSoD can't be resolved.

Your HDD doesn't always turn off. BSoD is Window's reaction to a stack overflow or memory dump. AKA bad coding. If your software cannot communicate properly with your hardware this may occur.
Consider backing up your files now and have a professional inspect your hardware. Often a bad HDD will report errors with other components due to bad sectors.

The Blue Screen of Death, as you call it, could have
several different meanings. It usually means your PC
has picked up a virus or even a trojan--which is... in
layman's terms... a double or even triple whammy!
But, as long as you can access your start menu, it's
often a good idea to do a system restore.
I'd gotten rid of trojans several times over the past 10
years that way.
Best of luck!

BSOD is a hardware (or hardware driver) problem. Without knowing the exact message, all we can do is guess. It could be your drive, it could be your display card, your sound card, RAM - any hardware or any driver for any hardware. All it definitely means is that something went wrong with your computer that was hardware related.

Sometimes it is bad, and sometimes it doesnt matter much. I get it sometimes, and just have to restart my comp, and it's fine. But sometimes it means you have a bad problem. it just depends.
