    maybe the stick is just plain defective? on the other hand, I would hate to go back to the store to exchange it, and come back home to find myself in the same no-go situation...
    just want to add ,turning off the switch is first step ,you then need to hold In the case power button to drain the power from the motherboard .then add the ram ,just a good step to add .

    Already made that clear, you would be amazed how long only power supply can hold charge, Even with not to overpowered PSU my computer does not turn off if power is cut for even more than a second, lights blink, monitor shuts off but computer stays on even as there's a lot of stuff going on. I repair PSUs occasionally and some times find a good charge in output circuit days after it's been switched off.

    mike, if you understand something about power supply, let me ask you:

    I once got a UPS but was disappointed with it. The electricity in my house was always going off when someone plugged in a wet clothes-iron or who knows what, we have 220 volts over here, so everyone has a safety-switch in the main electric box of the house that shuts down everything instantaneously when there is a short-circuit anywhere.

    I found that the UPS was not quick enough to react to that kind of power outage. It only worked for a general power outage, you know, when the whole street goes dark.

    What will work for my situation, if anything?

    You need to upgrade the circuit breaker box if there is no more available room for new breakers.

    If there is room, then you'd need to have an electrician run more power lines so the power isn't overloaded on any one circuit. The main reason for the circuit breakers is for the wiring (or failure in something plugged in causing short circuit.) There is only so much power that can safely be carried by NM-B cable. If too much, it can get too hot and melt the coating or cause a fire. So, that's why the circuit breaker trips - before anything like that is allowed to happen.

    As far as a UPS, what you are asking about simply takes $$$. The more you spend, the better. Anything cheaper obviously is not going to cut it.

    Another MUST for electrical wiring especially in the houses is GROUND, it is important not only for safety but for operation of whole system. Too manu houses, specially older ones do not have or is to old grounding and what can make that even worse is that there is no proper Neutral wire coming in so ground is used instead. In my neck of woods, there is 3 phase coming in, between any two phases there is 380v, neutral or gronud and any phase is 220v nominal. So you can see that if ground is questionable and us used instead of neutral you could easily end up with low voltage and a lot of fluctuation when something that pulls a lot of power is plugged in on the circuit that is on the same phase.
    As far as UPS is concerned, what MasterChief said is right. Cheaper and older models use electro- mechanical relay to switch UPS to battery and do not regulate much. Better ones use electronic, solid state circuit and react instantaneously to preset voltage drop and have reasonable voltage regulation.
    Another thing that might help even more is a voltage regulator which has a "bootstrap" transformer" to make higher voltage and than regulate it down to required voltage. It does not retain power when there's no input but is continuous and can handle "brownouts" and over-voltage. They might be cheaper too.

    Here is something that might help people looking for RAM , you don't need to buy the memory from them...but the app on the front page it's pretty good for recommending what's compatible with your system.
