Magnet vs Computer?

So, my brother in law calls me over to work on his computer because it is randomly rebooting after moving this past week. First thing I notice is the altec lansing subwoofer about an inch away from the case (this was not part of the system before the move).

Being that the computer was having these issues only since moving when this subwoofer has been next to it, I assumed the issue would be with the HDD since it is magnetically based. However, after buying a new hard drive and trying to install the OS, the computer would either hang while formatting in xp setup (although it would format fine in the HDD utilities program) or it would hang when beginning to copy files for installation.

Similar symptoms have been described due to cpu overheating, bad memory, bad psu. The question is, would a magnet cause problems with anything else? The subwoofer could be coincidence. Please let me know if you have any ideas.

Thanks.

 
I believe all a magnet does to a hard drive is erase whatevers on there, or screw up the files. RMA the second hard drive, then install Windows, make sure the subwoofer is nowhere near it, if it still reboots then you can rule out the subwoofer and hard drive.

Can you please elabaorate a bit more?
What is the model of the speakers?
System Specs?

The magnet in a subwoofer is nowhere near powerful enough to cause magnetic interference with your system.

Ribbon13 has 1000watt titanic mkIII right next to his computer with no issues.

The magnetic field created by a magnet decreases exponentially with distance. You would have to have a very powerful magnet right next to the actual harddrive to have it be an issue.

Try other things. Make a bootable disk with memtests on it. Check that out first.
 
The motherboard is a biostar m7vkd with an athlon 1900+. He has 512 of RAM but I don't know what kind since I am now back at home. I did look at the power supply and it wasn't anything I am familiar with. Therefore, it was not namebrand. The speakers are a three way but I don't know of the model. Unfortunately, I don't know as many specifics as I should. I am just not sure where to go next with this. Maybe start at power supply, RAM, CPU. The CPU temps were kinda high at 60C. The thing I can't get over is the system was working fine until he moved to a new house where he placed it next to the subwoofer. Maybe just coincidence. I guess I thought hard drives were more sensitive than that. Probable he just has components going bad. Maybe I will just have to build a new system for him.

Other ideas that may be causing these issues? If not the sub, then maybe just the move itself? Anything specific that has a hard time with moves? My only guess would be the cpu with a heavy hsf hanging off of it. Thanks for your input.
