DFI Lanparty UT X48 won’t boot

Hello, friends,
I recently bought one DFI Lanparty UT X48 from a guy (in addition to another .775 MoBo), just to play around a bit and then resell it. He had stated in his ad that he had experienced booting problems but swapping the RAM sticks solved them.
Now the motherboard won’t boot up. Actually I think it did, the first time only – I entered BIOS, then switched it off and this was it. It doesn’t give POST beep, the display shows 8.8., CPU fan works.
I have tried with the following components, tested successfully on other rigs:
- Two CPUs – E3400 & Q6600;
- A few different RAM sticks, one by one, in all four slots;
- A GeForce 7600GS videocard (in both PCI-E slots);
- A Thermaltake 550W PSU (which was also on my own rig until recently); (yes, I’m plugging the whole 8-pin power connector next to the CPU);

In order to reset BIOS I tried both methods: 1st with the jumper and then via the onboard power & reset buttons (I learned this from the manual)
I can’t see visibly bad capacitors.
Is it GAME OVER?
Can a bad PLCC BIOS chip result in this behavior?
 
seeing you said it starts and you can enter and sit around in the bios with out a issue there tells me the board seems good but if you go farther like to boot to desktop is when it fails ??? or is it now you cant enter bios at all?? also what about the psu are you using the same one or have you swapped it out with another to see if it was having issues??

Sorry that I wasn't precise enough.

I managed to enter BIOS only the first time. Now the screen won't light up at all.
Also, why not post sound? Like the CPU is dead, but it isn't.
 
kinda hard to say dfi is long gone , but I did find this

well don't know on that with out having hands on .. we could guess all week long and never hit on something as far as resetting the bios one more way would be remove the boards battery for x amount of time when the boards discharged from the psu ... most time it would go in to a loop like come on for a sec or 2 and turn off and come back on over and over ..

Thank you for this guide. It's really elaborate and comprehensive!

Actually I have some news on my problem. I noticed what I believe was a burnt SMD capacitor in a rather hidden place, near a CPL-4-50 inductor and practically underneath a heat-spreader.
