Hmm my guess is GPU or monitor fault. Can you try a different monitor? Also can you plug in another device to your current monitor and does it work ok?
looks like a windows issue because your steam icon keeps reloading. does it happen in the beginning at the bios screen splash screen? when exactly does it start flashing?

I didn't pickup on that, I'm changing my mind as I think this is more likely.
Its still the same w/o the gpu and the spazzing only happens after the welcome screen EG. (username)

I would recommend reinstalling windows as this is most likely either a driver issue, wierd windows issue (had the same thing on xp and 7 couldn't fix it and was forced to reinstall), or your storage device that windows is installed on is breaking.
You can also first try to create a new account as it sometimes happens that certain problems are bound to a user account.
