I just installed PCCHIPS Model # M848A motherboard in my computer with an Athlon XP 2400 Processor. I removed this processor from this case and old motherboard where it was working fine. I reconnected everything to the new board but can't get it to even boot up. Originally it wouldn't even power up. I changed the cmos jumper and got the processor fan and video card fans to power up but nothing else not even the LED's on the front of the case. Please help.
