Windows 10: License Key Missing After Crash

So, after going through all kinds of headache with this:
Move Installation To Another Machine

I now have my desktop back.

But somewhere during the whole ordeal, the license key became invalid.

The machine is a Windows 7 Ultimate that was upgraded through the free upgrade process.

Any help on getting the Validation back on the machine is very helpful.

I have the original drives from the machine intact, the machine is running two new drives.
Of which one of the drives will be needing a replacement soon, ...

Ok, the edit was because the browser attached a screenshot of the browser to the post, wtf?

:)

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.
