Computer Won't Boot After Adding Second GPU

Single GPU will run @ X16.how do i change that setting?and what are the disadvantages to running at 8/8 as opposed to 16/16? So, they using dedicated PSU's, they working (i try disable 1st - 2nd work perfectly on 450 W PSU), and windows still freezing on boot with two GPU's on CFX. That said, make sure all connections are done and proper and if you're still using the old PSU that isn't the crux of your problem. But most certainly for gaming it's a little less punishing on your system. his comment is here

it just may be the case the whole system and all components including the new GPU just isn't enough power. It's mainly the fact that it won't post (make sounds on start up) that tell me it's a motherboard issue. This is my new video card:http://www.asus.com/Graphics_Cards/GT6402GD3/This is my motherboard:http://www.asus.com/Motherboards/P5VD2MX_SE/I believe this is my old video card:http://www.gpuzoo.com/GPU-ASUS/EAX1300PRO_-_EAX1300PRO_TD_256M.htmlI'm not sure, because my computer told me the one thing, it said something similar but I see a HD 7850 energy consume - it about 250 W at 100% load.

It also hangs at the same place where it did before. Sorry, I would have swapped the PSU out just to cover that side of things. edit: errr.. If your MB has bad caps ...

i would just do an RMA to the MFG. http://www.gamespot.com/forums/pc-mac-linux-society-1000004/having-problems-installing-my-second-gpu-please-he-31781945/ Okay, I know I am coming into this thread late, but I had the exact same problem a few years ago, and that was my (simply solved) problem permalinkembedsavegive gold[–]Darkreddit306[S] 0 points1 darksusperiaMember Since: September 30, 2004Posts: 6945darksusperiaFollowForum Posts: 6945Followed by: 0Reviews: 0 Stacks: 0Forum Karma: 0#24 Edited by darksusperia (6945 posts) - 2 years, 28 days [email protected] said:@04dcarraher said: if you have Flag Permalink This was helpful (0) Collapse - This is why I looked at the PCIe power capabilities.

However, you say it doesn't even boot-up with the old video card, so you see why us posters refer back to the PSU as a possible issue. this content really looking forward to putting this behind me.Could this be because the clock speeds of your GPU are different? Also, its very common to have fans running when booting-up and still no display, because that a sure sign of bad or poor PSU.

Everything that needs to be connected is connected, in the video card manual it states you do not need extra power supplies for it to work, you just put it in

After research figured out your not meant to push each cable in all the way, anyway glad your up and running post here what kind of performance you get. X - Hello! You're down to 600w at that point. It's happened to me before.

After i disable ASUS GPU TWEAK autostart and reset overclock system freezes was gone! Check the specs of each card, google for that and then compare them.
