First of all: I wanted to buy a new motherboard I necessarily mean that DDR3 bar now has the delivery was installed within 3 days since (normal) with my CPU it new memory etc Windows then reinstalled the shock. NOTHING GOES! I have to find everything in my power to try mistakes have 32bit Win7 Home to Win 7 Ultimate 64bit none of these Windows versions run longer than 2 weeks. Otherwise, I'm just plagued by blue screens and "unexpected shutdown". all very strange RAM test I have already made countless with the result that no error was found. Hard drive is also fairly new graphics card has worked flawlessly. Since I can not tell whether my mistakes on the motherboard are another source or spring 3 stars because I am otherwise very happy with the driver software and the connection options.
