Hi everybody,

I'm using an arduino UNO on Win 7 64bit.

After a Reboot, everythings works fine, I can upload sketches and all. However, after a few uploads, my computer freezes completely (No mouse movement or anthings, only cutting the power helps) shortly after attempting an upload.
I have this issue on another machine (both slightly different Lenovo laptops) as well.

- I don't have the LVPrcSrv.exe service running
- Since I use the Arduino UNO there's probably no point in updating the FTDI Drivers
- I tried with IDE version 1.0.0 and 1.0.3

I haven't found much other troubleshooting info. Does anybody experience the same? Any Ideas what to try?

Thanks for any suggestions,



Windows reports some failure after the freeze? Can you check eventvwr.msc for critical errors? Can you check if there are minidumps created for every freeze? (PC properties, advanced, advanced, enable dumps)

I am guessing the problem is some electrical issue with your usb port.

Thanks for the fast response

minidumps are enabled, I do have some in the windows folder, however none of them belong to these freezes (last one from may).

Windows doesn't report any failures after restart. The only critical error reported was:
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

I can confirm this issue!
exactly the same as described above.

I use a Lenovo x201 with an i7 and indows 7x64 as well...

lets hope someone can find a solution...

It just happened again, although this time i did not even upload anything...
The USB connection with the UNO was established and the sketch editor was open.. and then everything froze....

Please someone help, this is so annoying it kept me from playing with the Arduino for a whole year.....
