Hello all,
The problem that i'm having is with my two, just purchased, xfx HD 4870 video cards hooked up my system crashes as soon as I install the drivers. Afterwards I cannot even get windows to boot up. It will start to boot and then just reset. If it by chance makes it to the desktop it will reboot soon after. No errors just as if I hit the reset button.
I originally thought it was the drivers so I tried multiple versions and the same effect
However, with one card removed the computer runs flawlessly. I want to say it might be an issue with the power supply but I'm not 100% certain.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817703005 is my power supply. It's a decent enough PS but the issue is that there are only 2 PCI connecters and each card requires two. But, I used the 2 4 pin to 6 pin adapters that came with the card to hook up the 2nd. I know this isn't optimal but would it really supply so little power that the computer can't even process windows? I could understand maybe having issues under full gaming load, i.e. crysis or something of that nature. It's a 12v single rail PS so it's not as if I should be overloading a rail.
I ran out of time so I didn't get to swap the two cards to make sure it's not just a bad card out of the box, but I'm hoping to have some insight when I get home from work. What can I check to see if it is indeed the power supply? Or a possible work around to the solution. I may just end up ordering another PS but I really can't imagine that it cannot support these cards to at least run windows.
Here are the rest of my specs:
AMD Phenom II X3 720 Black Edition 2.8 Ghz
MSI 770-G45 MB
Corsair XMS3 4GB DDR3
and of course 2x XFX HD 4870 1GB 256 bit GDDR5 cards.
Thanks in advance for your time.
