Hi, specs in sig.

When I boot into XP, nvidias sentinel appears telling me the GPU isnt recieving sufficient power. Never did this before. The Antec 550watt should be enough to power my rig. Also, occassionally there are green lines all over the screen that flicker like crazy. Do you think my GPU is dying or my PSU is going bad?

I'd also like to add that I really hope it's not the GPU, since its fresh from an RMA and its the 'reloaded' version of the 7900gtx, with the supposedly fixed dying memory chips.

Post a screenie of speedfan so we can see your voltages. I had many (5) Antec PSU's go belly up on me in many weird ways.

Speedfan shows 11.99 and 3.26 which is pretty well inline. The green lines usually only happen at bootup and stop. Very strange.

Heck, there was a thread here a while back about the same exact thing..good like finding it though.

Wish I could offer more help.
