USB port gets only 0.2V + BIOS POST freezing!!!

Hi,
I was writing to this group before, but I didn't get the answer. So here is my problem:
I got ASRock P4VT8+ mainboard (800MHz, DDR400, ATA133 ...) from friend. When I put Celly or P4 processors I get only BIOS POST screen showing CPU model & speed and memory size and here is where it stuck.
I can't get into BIOS, it doesn't gets to point where it should detect IDE drives. I measured voltage on USB (between +5V and GND) and it gets only 0.2V!
Prior to turning ON computer I had to solder out one element (there are four of them, near processor, black quadratic element with printout on them: 70L02H 418185) because it was faulty (checked with multimeter)
If I connect this element to mainboard it would burn my PSU (it did to one PSU!)
What do you think, where could be a problem?
Please, any help would be great!
