I thought my vista was being unstable because of my RAID so i took off the RAID and formatted both disks. I installed Vista on one disk, and it is still being unstable and blue screening...I have one minidump file. Can someone point me in the right direction as to what this is? When I turn off the computer I can hear a loud spindown on the WD which leads me to test the hard drive. I am doing a diagnostic on the hard drive but that's all I can think of. I have an Epox 9npa+ Nforce 4 Ultra socket 939 motherboard 2 gb gskill ddr400 8800gt video card wd 160gb samsung 160gb Thanks.
