  5. V***r

    All as in the description. It can be seen that used, for scuffs on stone. The processor is working, only I had to not crawl bios to update on the motherboard gigabyte ga-p35-s3g. Without updating, the processor is not recognized as it should (I started to restart forever, reaching the logo of the operating system, and when trying to reinstall everything at all). What is this… it may be useful for anyone to use this information, so as not to scold the store. So thank you to the store and people in it working, for a quite working and more productive detail.
