I built a computer last year in october, since then if has been out of commission most of the time since I got it. I would end up having a fatal error with windows within a week, I would search for a solution but would end up doing a fresh install of windows every time. Recently when attempting to wipe the partition on the drive and reinstall with the 64 bit disk all the options were greed out so I put the 32 bit disk in. I installed 32 bit a few days later after forgetting I had put it in the disk tray. After installation the computer ran fine I could use it without any crashing or burning. However I have 16gb of ram so I needed to use 64 bit, once 64 bit was installed the whole computer went to ****. I have constant crashing and after a few reboots the computer just went black. Does anyone know why 32 bit is running great and 64 bit seems to have issues, and should o just upgrade to windows 8?
