Magnetic Fields may have caused problems with my laptop.
Hi, I was messing around on my mates laptop, and I used a speaker box to lean on. When we come to turn the computer off it took forever so I just had to manually shut it down. When I come to turn it back on again it was loading up as far as the windows logo then the blue screen of death was appearing and restarting the machine, and this just happened repeatedly. I was wondering if the magnetic field coming off the speakers in the box have caused this issue? And how would I go around fixing this, is it a case of reloading Windows XP on or buying a new motherboard?

Re: Magnetic Fields may have caused problems with my...
You would have to have concert speakers next to the laptop to have that kind effect on the hard drive, the system is detecting a software or hardware issue, try to read what the blue screen says, most problems are to do with the system32 folder in the windows directory, which mean you have to recover the system, you could try to remome the hard drive and memory and clean the contacts to see if that makes a difference but i doubt it will work.

It sounds like there are some magnetic fields around your projector. Similar to what used to be degaussing in an older tube TV. Sometimes it may be that the speakers are to close to the projector or even the earths magnetic field that may be effecting it. Try turning the projector in a different direction and see if that helps your problem.
if you are using lcd monitor then it will not do any damage to it. however, if it is a crt type of monitor then yes it can or may damage the monitor. if the speakers do not that they are shielded then you should assume that they are not and should be placed away from the crt monitor because the speakers magnetic field will affect the crt magnetic filed used to display the picture on the screen. speakers with high magnetic fields and are unshielded should kept away from crt type monitors! lcd monitors do not use magnetic fields to bring a picture to the screen so it will not affect these types of monitors. you nay also check your user's or owner's manual for more information on you speakers and maybe check any of the manufactures web site as well. but it better safe the sorry to keep the speakers away from the monitor in question.
I think your TV has beam convergence problem. Depending on the model there may be user adjustments on the TV to align the beams on to the same spot as close as possible so that color shadows are minimized. Strong magnetic fields such as nearby unshielded speakers can also cause this problem. If that is the case, moving such magnetic field sources away may be the only solution.
You have analyzed the problem... with the strings muted, the unit is quiet... that means the problem is with the guitar or cable picking up the noise. Move the guitar around near other things to search out the source which is probably magnetic fields... orient the guitar differently to sniff for the source. OFTEN lamp dimmers generate higher frequency components that can couple into the guitar pickups. The problem is fairly common.
You likely are in an area that has magnetic fields. Also you may have the settings on the amp that accentuates the noise. Eliminating this noise, especially at low levels, can be difficult if you have devices like flourescent lights that have magnetic ballasts.
You might also try running a different source into the amp such as a walkman player to verify the audio can be cleanly amplified. If that works, then the amp is OK.
It's due to the magnetic field interferences from the speaker. At the first place, you shouldn't keep it near the speakers.
Always keep speakers far away from the Monitor.Now turn off the monitor and turn it on again,hope it solve the problem. You may even need to restart the system.
Moving magnetic fields (such as from an electric motor) can cause
flickering when near a CRT screen. A static magnetic field, such as
from your computer's speakers, can cause color shifts or incorrect
colors in the area near the magnet. This color shift is caused by parts
of the screen becoming magnetized. Occasionally the color shift will
remain after you remove the source of magnetism. To help reduce or
eliminate the color shift, you can use the degaussing option on most
monitors. Most newer monitors automatically degauss when you turn them
on, while older monitors might require you do to it manually. Most
monitors have a button or menu option that enables you to degauss it
manually. Degaussing a monitor will de-magnetize the inside of the
monitor, removing the color shift. Unfortunately, if the monitor is
exposed to the source of magnetism for too long, degaussing will not be
able to clear it up, requiring you to repair or replace the monitor.
You can, or you can save your money and do it yourself by using a speaker in your car. Open the trunk of your car and you will see the bottom of the speakers that are in the rear window deck, the cone of the speaker has a rather strong magnet on it. Stick the hard drive on it for an hour or so, and if you want to be thurough, you can flip it over and let it bake on the other side for another hour or so. The trunk speakers in most cars have a strong enough magnet to scramble if not completely erase a hard drive. I've seen laptops that have issues after their owner threw them up in the back window while driving around and left them for a while. Those speakers have a pretty good magnetic fields. I discovered this when a young lady brought me her laptop to be reloaded, because her now X had stuck her laptop to the speakers in the trunk because the magnet would hold it upside down and that was cool (IDIOT). The young lady was a nursing student at a local college with a ton of unrecoverable data and class work on her laptop.
