OK, so heres the gist, Can I power my PC through the normal installed PSU and my graphics card through a separate PSU lying on top of my PC.
Heres the detail,
I recently installed a second hand (from a good friend) x850xt gfx card, the system runs fine until I start playing games and then I see stutters and then random lock ups, ctd's, reboots etc. ive played around with various drivers etc, checked connections and ive come down to 2 things, either its because I dont have XP SP2 installed (when I tried SP2 a while back it corrupted my sound :x so I reinstalled xp afresh) or its a power supply problem (see below for PC specs n bits). I dont want to risk putting SP2 on until its a last resort (you never know MS may have fixed the corruption problem with patches, hmmmm) and I dont really want to blow over $100 for a power supply to find it doesnt make a difference. I currently have a 350w PSU (generic, came with a cheap case) thats about 3 years old and I thought that to test the power supply theory I could just borrow another ~300w PSU and plug only the gfx card into it.
Now heres the beef, im worried here about floating commons, PSU's fighting to regulate each other etc as im not sure how much the power from the card input is linked/isolated to/from the power on the mother board through the AGP port.
So before I nuke every circuit and PSU in my PC I just thought id ask a group of like minded people the question of,
1 PC 2 PSU's, no worries or no way?????
any comments or discussions welcome.
Cheers

P.S. I read the faq and see the bit about diagnosing PS problems and, well, it could be!
