Here is my list of pre-saved Questions for newcomers:
What build # & Version of the Win_7 ?
Where did you get the iso file from ?
How did you burn the DVD ? At a slow x4 speed ?
Any Over Clocking of ram or cpu ?
Best to have 2gb ram or less for initial install !
Suggestion, remove everything not essential to loading Win_7, from the system.
No printers, gamepads, second monitors, scanners, external devices, flash drives etc... So just ignore the answers to the ones you have already posted an answer Looks like here we go again with another Trial & Error testing session. How about setting everything in the Bios to default ?
