Windows 10: reinstalling windows after a crash and everything was erased

I was letting my computer update itself and the power went off and when power came on I lost everything on computer and I can't reinstall windows because I was using Windows 10 after a free upgrade. My Dell computer had windows 8.1 factory install but now its gone too. I don't have any recovery discs at all and need help!

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?

 

Finally! An alternative to eraser...

it looks much cleaner then the eraser so that is a big step up.

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.
