Hardware:
R7970 lightning 1070/1400 (stock)
Crosshair v formula
coolermaster spg 800w psu
fx-8150
8gb g.skill ddr3 @ 2133 mhz
WD 1 tb green drive

The problem:
every time I open GUIminer and enter my info, I come across a "Verification failed, check hardware!" error message after several seconds.

To attempt to resolve the issue, I have:
Updated my video card drivers (from the windows hardware manager and manually through the catalyst installer)
downloaded and installed AMD APP SDK v2.5 (the most recent version)
benched my video card in Unigine Heaven (without any apparent problems)
checked my pcie power connections (1 8 pin and a 6 pin converted to an 8 pin.
underclocked the card (to 925/1375)
Mined with my cpu (successfully)

My guesses as to what the problem might be:
Not enough power to the graphics card (I only have power from 1 6 pin and 1 8 pin connector)
A compatibility issue with GUIminer
A bad graphics card
A driver problem
A bad video card

UPDATE:
I have recently been experiencing some strange bugs. everything on the screen briefly shifted down before returning to it's original state. I had some artifacts on screen, and stuff was randomly selecting and deselecting. A page started randomly scrolling up and down. Is this because of the gpu?

Nothing has worked so far, and I am getting ready to give up on bitcoin mining. Can somebody help me?

You might try asking this in the technical thread. There's not many people who still use guiminer now, so a reply here might be slow.
You're whitelisted.
