Windows 7 Instalation CD error

It had got to 56% with the USB then it said to verify the installation source

Then try a new ISO since the installer is clearly bad: Win7 Home Premium x64 SP1 English Official ISO download

Burn to DVD or write to flash stick using Windows 7 USB-DVD Download Tool

Boot the stick, wipe the HD first: SSD - HDD Optimize for Windows Reinstallation

i was already using that one is it ok if i dont use the latest wont it update its self?

It's likely you have a bad installer - either the ISO is not intact or the DVD is burned badly.

Confirm the ISO or download another, burn DVD using ImgBurn at 4x speed, or write to flash stick using Universal USB Installer

Ok so the USB worked I download windows and installed it and I was typing in he product number when I was the it wrong and it froze to I turned it off and started the comp normaly and I got this

Make sure the Win7 drive remains set to boot first, or unplug the other HD's.

Did the install complete? It normally asks for Product Key at the beginning of install. Why did you shut it down if it only froze?

If the install completed and booted into Windows then boot into the installer's System Recovery Options to run Startup Repair repeatedly.

If it froze before install completed, then test your RAM - Test with Memtest86+

Next reboot and enter BIOS setup, set BIOS to defaults, then set SATA controller to AHCI to try install again.

Half the time I try to load the USB it dosent work and I can only get into boot menu sometimes and I did get into the startup repair it said it fixed it and said reboot but still nothing

When I go to try and reinstall it says no drives where found

And for repairing I get no drives and when I click to find one I look for this

Well we took it to some computer people and they said it is now fried..
