The title of the thread says it all. When I finish installing windows 7 on my Gateway MT6451 my computer shuts down and files become corrupted, forcing me to install the OS again with the same problem repeating. So now I am on vista and things are running smoothly but I don't want to be on vista, I paid too much money not to use my windows 7. I thought the issue was the bios, so I reinstall my bios and attempted again, no dice. Next I checked to see if the computer was over heating, so I made sure my fan was running and the temperature of the CPU. Both checked out to be alright. I am wondering though if my cpu is still causing the problem. My motherboard previously had an amd TL-50 cpu in it and I replaced it with a amd MK-36. Both are socket s1's but my TL-50 was a Turion 64 X2 while my MK-36 is a Turion 64. I just don't know what to do. I am tired and lost. Please help me.
