I'll start of by giving a list of the components in my setup to give you an idea of what I'm working with.
Motherboard: Asus P5B (might be some sub-model; it's orange but only says P5B)
CPU: Intel Core 2 Duo E6850 @ 3.0 GHz
Memory: 3 GB DDR2
PSU: Colors-It 500W
OS:Windows 7 Ultimate (x64)
Current GPU: An old Sapphire ATI Radeon 9200 that barely works
New GPU that I can't get to work: Sapphire ATI Radeon HD 4870 (1GB GDDR5; 750MHz core clock)
I've properly installed 4870 and plugged in both PCIe cables, but when I try to turn the computer on, it turns on for a split second and then turns off, and tries to boot again, in a sort of endless loop. The computer runs fine when I unplug one of the PCIe cables, but Windows doesn't detect it. By the way, I'm using Molex to PCIe adapters since the PSU is non-modular.
If there is anything I could do to make this work, please let me know, and feel free to ask any questions about my setup. Thanks!
