I am not sure about the Windows 7 licencing system, but you are only allowed to re-install so many times. please check.

If this is a new machine, it could well be a fault and needs to be returned to the supplier, however as you have opened the case, it may no longer be under guarrantee.

If it is an older machine some of the components may not be able to cope with the increased load (32 bit to 64 bit & higher speeds)

Instead of turning off for the night, why not try using 'Hibernation' mode, to see if it makes a difference

Are we using the same terms?
You say-

1) "If i format and reload windows it is ok"

but you say later

2) "i cannot enter safe mode will not work."

Are you sure you meant in (1) format and reinstall?
If you do mean a full reinstall from the W7 disk, you must be totally fed up, and you can't even reach safe mode.

It may clear the matter for others who may also have the answer, but try and describe somehow exactly what you have done. The stalled blank black screen with cursor after the initial logo, implies obviously that Windows can't load.

Did you mean system restore instead of reinstall.
Maybe your DVD drive is faulty if you confirm the the computer cannot load from that drive.
