Do not worry NO harm done
My great concern was that you had ordered from Crucial
We know there are four slots, but how many of the slots have ram in I can see from the image that two do, I just cannot be certain if the other two do.
You will see if the clips are secured in place to the end of the ram sticks in the notch.
Again LOOK at the manual that I sent and the image Alzeimer sent
DO NOT TOUCH the ram components.
Take antistatic precautions take hold of the bear metal case inside with both hands,
CHECK if the clips are in place.
TO SAVE ME a lot of typing read the manual
THere is something WRONG as I have just referred back to the topic in malware when CompCav was helping and one of the OTL log reports says
]1022.09 Mb[/u] Total Physical Memory | 239.96 Mb Available Physical Memory
WHICH is 1GB
and the spec you have says 2GB and Speccy says IGb in TWO 512MB sticks, so either two sticks are dislodged or there is another problem.
