Hello everyone.
So I have a Dell Optiplex 780 SFF. It's the low profile PC but second from the smallest in this lineup. The original video card that came with the PC was AMD HD 2400 Pro and wasn't enough to play decent games so I purchased a Dell OEM nVidia GTX 745 card and installed it. Once its booted it works great and I can run World of Tanks on 1920x1080 pretty smooth, but when I push the power button to turn the PC on it takes 3 tries every time to turn ON. I mean, it powers up (fans spinning etc but no video yet) than turns OFF, then powers up again with no video and turns OFF, and 3rd time it powers up with video and boots to windows. Any ideas why that is?
See video card specs here. Thanks

Well, after few boots, it seems to boot fine. Go figure. Now its a pretty good low profile gaming PC :)
