Arduino Restarts Computer

I am new to Arduino and I think I might have overloaded the USB port when i was running the board a small servo and pot with the USB power. The computer restarted and displayed a registry recovery message.
Now the computer restarts when i just click to open the Arduino software. Everything else seems normal so far but anything Arduino crashes the system. Any help would be appreciated.

Does it restart with the board plugged in or not? Try starting the software without the board plugged in.

Is this a "name brand" computer or something a little more "inexpensive"?

Might be worth reinstalling the Arduino software. I wasted lots of time once chasing down some software problem which turned out to be caused by a bad ZIP program that just plain flat out un-zipped the archive improperly and corrupted the EXE.

I built my computer using an Intel D975XBX2 mother board and I am running winXP 64bit. I did use a free unzip program off the net called JistZIPit. However my computer restarts when I try to load the Arduino Application without the board pluged in. I have found that I have to run the Batch file in that directory and then every time after that the app loads fine but only in that windows session. Is that normal? I don't know how to reinstall the software. Does it really get installed as a program, or is it just an application that you load?

I have found the IDE to open, compile and upload without blowing up windows to work when I Run the batch file and allow the command prompt to remain open. Is it possible that there is some bug in the exe related to 64bit? Anyone else running win XP 64?
