| 440468 | 2006-03-25 02:00:00 | Thanks for help guys... Right then, disconnected everything to begin with and started it with just CPU fan and main power from motherboard, (no 4pinATX on this board). No RAM, no hdd, no floppy, no optical drive, no case fan. Still no screen after boot up. Added RAM, no change. Added hdd, no change. Added etc, alas...no change. All cables were unplugged, then replugged to check if in properly. So, shall inform him that he will probably need a new motherboard? (if they still sell boards compatable with cpu, Athlon XP 2200+) |

Something similar happened to me just recently when I tried to install an AGP video card into a new computer I repaired. What would happen is that it would no POST and I found that clearing the BIOS was the only way it would work properly. (Changing the VGA boot order did nothing) |

| 440470 | 2006-03-25 02:23:00 | Thanks for the suggetion Bob. took it out, waited 30 secs, replaced, no change. One thing I havent tried is lookiing on motherboard for one of those "Clear CMOS" jumpers, that reset motherboard settings I believe. Would this be worth a try? Was afraid to give it a go in case i stuffed it more, but its looking more and more like its toast anyhow. |

| 440471 | 2006-03-25 02:49:00 | If you just removed the lithium cell, with the power cord still attached you did nothing. Look for the jumper. :D | Graham L (2) | ||

| 440473 | 2006-03-25 03:00:00 | Same effect, but different means. Removing the cell (not just for "a few minutes") takes the backup voltage off the CMOS memory (as long as an ATX supply isn't still connected to the mains) After a while, the contents will be lost. A "Clear" jumper should tell the POST to actively clear the memory locations. | Graham L (2) | ||
| 440474 | 2006-03-25 03:08:00 | Thanks for the suggetion Bob. took it out, waited 30 secs, replaced, no change. Thirty seconds is not long enough. Try an hour or so and make sure it isn't plugged in after removing the battery. |

| 440475 | 2006-03-25 03:27:00 | The pc was off the mains when I did it, but it wasent very long. I'll leave it out for a few hours then this time. Thanks. |

| 440476 | 2006-03-25 07:17:00 | Replaced battery after a feew hours, but still cant even get to BIOS. After that, tried clearing CMOS with jumper, but same result. Any suggestions before I tell him to he might need to replace motherboard? |

| 440477 | 2006-03-25 10:49:00 | Have a look at the capacitors on the motherboard .. more info (http://www.badcaps.net/). It is of the right sort of time period for the issue. | gibler (49) | ||
