Usually a defective device or improperly installed driver for a device. Take a look at your Device Manager (in Control Panel) to see if one of your devices is acting up. You will be able to tell (yellow icon) which, if any, is having a problem.
Once you find the problem. Try to reinstall the drivers for that device.
i looked at the device manager and no yellow icon. What other reasons might there be that it crashes upon reset?
