Bad memory module? Or bad slot?

Your module is bad, slots are fine. The system BIOS looks to SLOT 1 for a memory module, if it does not find it, the POST fails....this is because the memory bus is serial and not parallell (as in old systems)

you could try re-seating the reminiscence module, even though it could actually be undesirable. reminiscence can circulate undesirable over the years. earlier you commence, verify you're no longer too staticy. do no longer try this on your socks on the carpet, and touch grounded steel each each so often (the screw in the midst of an outlet, working example). The reminiscence is possibly at the back of a cover on the backside of the pc- you're able to wish a screwdriver to open it. The reminiscence probable looks like a circuit board with numerous comparable chips working perpendicular to its connector. There must be a pair of springy tabs protecting the standards of the reminiscence, and via gently pulling them aside the reminiscence will probable hinge outward and could then be bumped off. in case you have 2 reminiscence modules, you ought to have the skill to limp alongside on one- yet you're able to could desire to go the solid module into the different slot. Or, as I pronounced earlier, it may paintings in case you eliminate and replace the module. it could have shaken loose. If there is not any longer a hatch on the backside, the reminiscence is probable below the keyboard. Do a internet seek for the particular sort of computing device, and you will probable discover out the place it particularly is.
