Default PC Motor Speeds Up after plugging in Blackberry

Please Login to Remove!

This just began happening. I plug my sync cord into one of the usb ports on the front of my pc. I then plug into my Blackberry 9000, when suddenly the pc motor revs up to a very high speed. I can do nothing to control the pc after that and must press and hold the off button until the computer shuts down. Once I turn on the computer again, everything is okay. This happening is not a regular occurrence, but it happens every so oftern. Has anyone encountered this?

Motor? PCs don't have a motor.

Perhaps the fan. The fan turns on when the temperature inside the PC increase. It is coincidental that when you plug in the BB, the fan engages.

Sorry for being a newbie. What it sounds like is when you insert a cd into the cd tray and you hear the sound of the cd engaging, but it is much faster and louder and by the volume of the noise, it sounds as if the pc is going explode. Am I making myself clear?

o, the question is, why does the fan speed up when I plug the usb cord into the usb port in the front of the pc? That port would be the "E" Drive.

Could be the hard drive.

Default Fan Motor increases when BB is plugged in

It is interesting that this only happens when I plug into the front in the "E" Drive and not in the back. It is also interesting that it is sporadic and everytime.

What OS are you running on the PC?

Sounds to me like you have a short in the USB port that you are using. Very common for the computer to reboot abruptly or kick fans into high-gear during an electrical short.

My suggestion would be to try a different USB port, if the same thing happens, try a different USB cable.

This is hardly a problem with your OS, your hard drive OR your fans. Electrical short is what it is. If you're feeling bold, no pun intended, locate the USB header that comes from your front-usb and make sure it's seated on the motherboard.

Failing that, most front/side-facing USB ports are great for convenience, but they tend to get abused, bumped, tweaked, yanked on etc. If the port is physically damaged, you may just have to stop using it until it is repaired/replaced.

Dig it?

C'mon guys. The guy is admittedly a newb. Go easy on him...

It is definitely the fan. The fan increases speed when the CPU gets hot. The CPU gets hot when it is under increased load (A foreground OR background program is running a lot). A background program will overrun when it processing something very hard OR is stuck in a computational loop (usually caused by a bug). Since your OS stops responding, I am inclined to believe that this is caused by a bug that is taking high priority over the system.

Since this happens when you plug in your blackberry, I would think that something is going wrong either with Desktop Manager (unlikely, but try to uninstall/reinstall or upgrade it anyway, just to be sure) or with something coming from your blackberry. To your computer, your blackberry's device memory AND memory card both look JUST like USB drives (USB keys, Thumb Drives, pick your name), so if it is set to "Auto Run" and there is something on there, it can run whatever is on the drive. That said, it could *also very unlikely) be some type of malicious program.

It could (also unlikely) be something wrong with your computer (Operating System), specifically with the libraries that run when a USB device is connected.

So, I know that none of these really help, but maybe it will give you a boost on how to solve it. Like I said, first rule out Desktop Manager to make sure that it is not the problem.

Good luck!

Oh yeah, and the fan is driven by a motor, so the PC DOES have a motor...so there! (The Hard Drives and CD Drives have motors, too)

Come on now... this only happens when he uses the front USB.

No malicious program, OS, library/dll, etc is going to single out the front USB in this fashion.

Hands-down: The front USB port is shorting out, causing the computer to lock up and the fan to kick into high-gear. Fix the front USB, problem solved.

I'm willing to bet on this one.

That's true. On some laptops, when the BIOS freezes and fan control is killed, it defaults to the max. speed. Good call, I should have thought of that.

We're sure that it doesn't affect any other ports? Also, what's troubling me is that the trouble is intermittent.

Anyway, and again, good luck!

I was only thinking, because when I plug my BB in, and use mass storage, it comes up with the "what do you want to do" box etc etc and with vista, mentions something about clocking the speed, making the drive faster...something like that. Figured it might be that using that port, it defaults to opening that option as opposed to view files.

Windows Vista has the "SpeedBooster" portion of the operating system. It will prompt you with any removeable storage device, if you would like to use it as extra memory.

I've used SpeedBooster with a cheap 256MB USB thumbdrive, and let Vista use all 256MB... didn't really see a difference, small drive.

You can set what removeable media prompts you to do in Folder Options.

I'm still set on the short.

I wouldn't recommend having the kid pull his front usb from the board Lol. And yes, it's a short in the usb because there's nothing in this world that can make a computers internal heat to rise just from plugging something into the usb port. Just take his advice and use another port.
