I did a fresh install of W7 ultimate and it installed fine, but on it's first boot it started hanging at windows is starting, after a few mins of a black screen it loads up fine.
I have tried booting with everything unplugged but it didn't help, the pc was running fine with W7 before.
It would be good to know what your spec system is? What version exactly of 7 did you install? Did you move or change any hardware or remove any connections? How did you install 7 on your computer?
Try resetting the CMOS on the MB.
As per OP it is windows 7 ultimate and it was a fresh install.
System runs an AMD sempron 3500+ cpu, 2gb ram, unsure what mobo is in it.
I haven't changed anything in the PC and it had W7 installed before.
Thanks eric, i'll give it a try.
