Mainboard will not boot EXCEPT with "clear CMOS" jumper set. Intel D945GNT barebones. no cards 1 dimm. swapped PS, RAM
I can boot into BIOS w/jumper ser and change settings; but when I save and exit it tells me to replace jumper to normal position and cycle power. Upon power cycle, the board just keeps resetting every 4 seconds. (I see the NIC negotiate a link then reset.)
1) Will boot 100% of time into BIOS maintenance mode (Jumper 2-3)
2) Will boot 0% of time in recovery mode (jumper removed) - tried about 30 times
3) Will boot 20% of time AFTER exiting maintenance mode and power cycle.
Once it boots (3), it will continue to boot after pressing reset button or power switch, but stops working if I turn off power supply.
CMOS battery shows 3.07 Vdc.
Tried BIOS recovery (recovery file on USB drive, jumper removed) - won't read drive - failed
Replaced power supply - no change
Installed SATA drive - no change
Installed ATA drive - no change
Tried 8 different DIMMs different speeds, sizes and slots. known compatible & working - no change
Ok it may show that but is your battery completely new? Or is it the original that came with the motherboard? If it orginally came with the motherboard....that board is like at least 3 years old now (which is a long time in terms of computers).
