Those rubber looking things you see are metal clips embedded in plastic, the clips connect two pins together like a switch, the plastic merely makes it easier to grab onto the clip and the clip slides down over the pins.
Based on what I have read, I am beginning to think those jumpers are most likely set to their default settings. It is my belief that if they had been changed by you, you would have known what they were for.
You stated that you had two sticks of RAM in your computer and you removed one stick thinking your system was crashing because of the two sticks being in the RAM slots at the same time.
Are these the same two Team Elite RAM sticks you tried before?
Now your tests conclude that if you insert one
of either of those two sticks in either of the two slots, the computer boots up successfully.
So this brings us to a conclusion that both slots pass the test.
You stated that those two sticks are a matched set.
The only thing I can come up with for why the computer fails to boot is that there may not be enough power going to the motherboard to power up both sticks at the same time.
Now I realize you had two sticks in this motherboard before and for the most part they worked, with the exception of a random crash here and there.
Power supplies are work horses, they have a lot of hardware to supply power to and get quite a workout, they also get subject to a lot of heat, power main disturbance, brown outs, power failure related damage. They take a lot of abuse.
Over time, the power supply can start loosing its ability to maintain the rated power output it originally had when it was new.
+12 volts can drop below 12 volts to 11.5 volts, +3.3 volts can drop to 2.1 volts, +5 volts can drop to 4.1 volts.
The only real way of knowing what is going on is to have a digital VOM multimeter.
Set the meter to DC volts and while the computer is up and running, look for unused power connectors that you can get a voltage reading from.
The black wires are always ground, they are also called NEGATIVE or (-) or chassis ground.
The black wire is where the black test probe from the meter should be connected to. Simply insert the probe into the back side of the connector where the wire goes into the plug.
The yellow wire should have +12 volts or a reading of 12.0 or higher. Make sure the red probe of the meter and the black probe never touch each other while they are in these positions or you will short out your power supply.
The red wire is +5.00 volts, a reading off of the red wire should be at least 5.0
The orange wire is +3.3 volts and should be close to that reading.
During these tests the black probe can remain on the same black wire.
Now let me be clear that if a meter is used and since the power supply is under load (meaning its resources are being used up by the hardware) the readings can safely be a few micro volts higher or lower than the initial rating. However, if 12 volts is reading 11.2 or 3.3 volts is reading 2.5 volts, that becomes a problem, because the demand is higher than the supply. Some computer components require a stable constant supply at or above 12 volts or 3.3 volts.
Anything less then the required amount, causes transistors to oscillate off their required frequency, amplifiers become switches and switches act like amplifiers and the computer system runs very unstable or not at all.
I want to apologize to you for getting really technical and long winded here in this post about how electrical circuits and power supplies work, but also realize the more you know the better it is for you to understand.
I can teach a person in less than 5 minutes, what took me 38 years to learn. It is not that it takes 38 years, it is the experience I am talking about and the money I invested in college and getting a license to do commercial related repairs.
Any questions you have I am capable of answering for free.
Because I know my question was buried in my rant and would most likely not be answered, I'll ask it again.
Is the two sticks you are attemping to use now, the same two you were using before?
