PS/2 mouse & keyboard.
Upon power up case fans run, Video card fan runs. CPU heatsink becomes warm.
But no bios post, no beeps, no disk activity. Have checked my connections again and again.
-two different power supplies 300W, 500W (brand new)
-two CPU's (XP2800+, XP2400+)
-three different video cards, 2 PCI, One brand new AGP
-three different memory sticks, alone or in combos, in all possible DIMM slots
-removing all connections exc. video, K/B, mouse
-removing all memory (no beep codes result)
-cleared CMOS, removing battery for 3 mins in process
-removed board from case to check for case shorts - no change
-RMA'ing board from TigerDirect - replacement board exhibits same behavior and the one I returned.
At this stage all I can think of is that both my CPU's decided to die at the same moment. Seems very unlikely and unfortunately I dont have another compatible system to try them in at the moment.
