Thanks hchu and impeachbuch.

I tried with a new PCI video card (VisionTek Radeon 7K) as you recommended, but unfortunately I still don't get anything on the screen.
I am still trying to boot with the minimum components, as my goal is to get to the initial BIOS screen.
Is it possible that the MB simply did not detect the video card because it is not in the PCIe x 16 slot?
If the answer is no, the suspect is narrowed down to the MB, the PSU, and the CPU, from the most likely to the least.
I am confident I did not electrocute the CPU because I never touched its pins.
Does the CPU have to be functional to get to the BIOS screen?
BTW, I am not using a CPU fan (for that matter no fan at all in my case). My case, a Zalman TN500AF, acts as a big heatsink, and heat from the CPU, the video card, and the northbrige is transfered to the case by metal pipes. For more information, take a look at

The MB manual does not say that a CPU fan must be attached to post, so I assume it's not an issue.

All the components except the case have been recently bought from newegg.com. Does yours show "FF" from the moment you power it on till you see the Windows logo on the screen?
