i had to format the machine because she was running slow
it wasnt the original installation cd (windows 7 home) but its deffo windows 7 home because then the key wouldnt work
it installed fine. everything worked up until i installed the windows updates. i then rebooted
now when it boots to the windows logo the screen goes blank but i can hear the login sound and then nothing
Iv stuck in the windows recovery and did a restore and attempted to fix whatever problems it had but nothing.
could there be a loose wire inside?
should i open her up ?

Welcome to the Forums.
Looking at the Windows 7 Boot Process, the OS loads up the necessary dependencies, drivers, and system registry hive as soon as the Windows 7 logo appears.
it's possible that during the Windows Update, the system installed a display driver or an update to the system files that's causing the black screen issue. If you're able to see a display during POST / Windows Recovery then there's no need to open up the machine.
To isolate, can you try one of the following:
1. Boot in Safe Mode (Windows will be forced to use a generic display driver). if this works:
a. Open Device Manager > Display Adapters > (right click) on the display device > choose Properties
b. On the Display Properties, navigate to the Drivers Tab and click Rollback Driver then hit Apply > then Ok.
c. Reboot the machine in normal mode and observe.
2. If you're using a Windows 7 Home Premium (without SP1), re-install the OS and temporarily disable Windows Update. When you get to the desktop, install Windows 7 Service pack 1. If successful, create a System Restore point and install the other updates from Windows Update.
Let me know how it goes.
