| 13227 | 2001-05-27 00:12:00 | when I start up my computer,just after it counts up the memory it stops with the line 'memory test fail'. I just press 'f1' or 'reset' and it seems fine,what is wrong?thanks in advance Don |

The best way to find out which one is to take them all out then insert them one by one and boot the system, see which causes the error. Thats your faulty chip, then you can take it back to the shop your brought it if its still under warrenty. |

| 13229 | 2001-05-28 02:53:00 | The fact the memory passes its checks after a reboot may point to a flat CMOS battery being the problem. This would cause the CMOS to reset to defaults when power has been off for a while. With older BIOS's the actual RAM is checked against the last recorded value and any variation will cause the fail message. A simple test would be to see if the system clock resets after the power has been off overnight. Alternatively you could check the battry voltage. It should be no less than 3.0 vdc. If it is a physical problem with the RAM then it could be due to cold, moisture, or dirty contacts. As the RAM works ok after a reboot, faultfinding could be difficult. |

| 13230 | 2001-05-28 08:01:00 | k1w1 -my mother board is just over two years old,how long does the CMOS battery last? + it is getting cold and damp here so I will leave on form now on.thanks Don | Guest (0) | ||

| 13233 | 2001-05-28 14:36:00 | A CMOS battary should last about three years, but I have received brand new motherboards with flat batteries. A cold environment would tend to affect the CPU and RAM more then anything else. Either could have electrically stressed by incorrect handling during assembly. This means they will show signs of premature aging. One of these effects would be to reduce their operating temperature range. Moisture can effect power supplies, but you would normally hear some sort of crackling or humming until it warms up and dries out. The real danger with moisture is corrosion. This can produce a multitude of problems. I would suggest you have a look inside the computer for any signs of moisture or corrosion. Dried up water and corrosion will appear as a whiteish coating on most surfaces, but soldered joints can also look very black instead of the normal grey/silvery colour. |
