I wanted to install Windows 7 x64 Ultimate onto my brand new computer and the installer freezes every time at the "Expanding Windows files" screen, not always at the same time, e.g sometimes at 44%, sometimes at only 80%, or it also happened that the machine rebooted in the middle of the process without prompting or anything. Since I was unable to install the x64 version, I tried to install the x86 version, or e.g. Professional instead of Ultimate, with no success, because it also freezes the same way. I also tried installing from a different DVD, even from a pendrive, but this doesn't solve the issue, the setup just freezes at the same point. Unfortunately I'm also unable to install Vista instead of Windows 7, because the problem still persists. It seems that none of the above systems work...
To be able to use that computer at all I wanted to install XP then, but I also have issues with XP, because the machine also reboots sometimes without prompting, it also rebooted at the end of the installation process without any reason(when finalizing settings, such as users, automatic update, etc.) On XP, I'm also unable to install the graphics card drivers
(ATi HD 5770), because after installing the Catalyst software suite, there is no picture at all after rebooting, after loading the system, the screen simply goes black, then the only thing I can do is to start up in safe mode, and to remove the driver
Since I also encounter problems with XP it's likely that there's some hardware problem...if this is possible, then what can I do, or what might be the reason? Thanks in advance.
