Really, all he needs to do is check for memory conflicts.
Funny, I can check the memory assigned by XP to my ATI 4800 Video Card.
I still think it is a power supply issue. Regardless, replace it anyway.
I have never used Windopes 7, but I very much doubt that it differs in this regard.
And all you need to do is use "Device Manager" to check for conflicts on one working boot.
Yes I understand that, but you did say earlier in the 5th post to this thread that :
"It's now failing the first POST, then looping and booting correctly the second time."
Which is why I suggested that you check for memory conflicts. If you now can't get it to boot at all, then maybe you should replace the power supply; though one other thing you could try first, is shut down the machine, and then use the jumper on the mobo to "Clear the BIOS".

http://support.microsoft.com/kb/314068Manually assigning IRQs to PCI slots in the system BIOS as a troubleshooting method may work on some non-ACPI systems that use a standard PC hardware abstraction layer (HAL), but these settings are ignored by Plug and Play in Windows if ACPI support is enabled. If you must manually assign IRQ addresses through the BIOS to a device on an ACPI motherboard, you must reinstall Windows to force the installation to use a Standard PC HAL.
The ZT 650 is a good power supply. Overkill for your 5770, but still a good PSU nonetheless.
One other thing you can try, is shut down the machine, disconnect your SSD and HDD if any, then clear the Bios, then power back up with the SSD and HDD disconnected to see if you can get video to get into the bios with them disconnected. If you can, then it may be a "Setting Problem" of some sort. If you can't then it pretty well has to be a hardware problem.
i'm thinking of an upgrade, something along the lines of a 660ti or 670, or cheap AMD such as 7870 7950 etc.
That, plus the power supply, a case and maybe a monitor.
The purpose of disconnecting the SSD and HDD, prior to clearing the Bios, then booting to see if you can get video to get into the Bios, is to remove Windopes from the equation.
i.e. If he then can get video to boot into the bios, then it may be a Windopes issue, if not then it must be a hardware issue. One other thing I would point out, is that when I first built this machine that I am on, it would boot into a "BLACK SCREEN" because of "DEFECTIVE RAM"; i.e. "Buffalo Select" RAM that would not support it's default timings; though it would work OK if you slowed the timings down. Changing the RAM solved the problem.
