how i solved event id 41 windows error

     Hy! I had this error first time when i starded using a linksys wusb100 v2 usb wireless adaptor in conjuction with a windows 7 64b operating system.
    I installed the official drivers found on linksys cisco page.
    The wireless signal was fluctuating all the time with those drivers!
    After that,  the infamous event id 41 started to appear 2 or 3 times a day with computer restarting!
   
    I  set the computer to record a kernel dump file on error and opened that file with windows debugger (available for download freely). The error was there and was caused by rtwlanu.sys - a file used by linksys usb wireless driver.
    After many searches on the net, i found the driver for ralink wireless chipset used by linksys wusb100.
 
   Installed that driver from ralink and event id 41 error was gone!


   On another PC i had the same error but, this time, no kernel or memory dump file were recorded on the hard disk no matter the settings made for this job! Suddenly, the pc was restarting and the system was able to record that an event id 41 happened but no memory or kernel dump file was present! The operating system was clean, a good windows 7 64b!  Ram memory was good, hdd was good, the computer had the hibernate and sleep state disabled.
    After 2 or 3 weeks i discovered that this restart - event id 41 - was present when the computer was loaded with intense calculus tasks, such as converting hundreds of raw images to jpegs or gaming. So, this error had to do something in common with the electrical power used by processor.

     I replaced the power supply with a new one and... bang... the event id 41 dissapeared!
