Hello,
The problem with my PC is that it won't boot if a graphic cards that needs two pci-e powers cable is connect to the pc. More precisely my pc only boots with either no graphics card or a graphics card with only one pci-e (6 pin) power cable connected to it even with cards that need two 6 pin cables (but then I have no display).
For example I have been using a GTX 460 for more than a year now with no problems even until last night and a gtx 260 for about three years before that.
But now my pc won't boot with either my gtx 460 or my gtx 260 if they have both of the 6 pin pci-e power cables connected but will boot up if only one 6-pin pci-e power is connected but the monitor has no display (goes on standby). So then I dug up my old geforce 8800 gts card that requires only one 6 pin pci-e power cable and with that my pc boots up and turns on just fine with windows working properly.
The specs for my pc that I built back in 2008 are:
PSU - Zalman ZM750-HP 750W
MB - Asus Maximus II Formula
CPU - Intel Q6600 OCed at 3 GHz
RAM - Corsair TWIN2X4096-6400C4DHX (2x2GB)
GPU - Gigabyte GTX 460
OS - Windows 7 64bit
Now my question to you guys is do you think that this problem with the graphics pci-e power problem is a problem due to a fault with my motherboard or is it a problem with my power supply? Or do any of think that something else might be the problem?
