Is the
"1" on your keyboard located on the top right hand corner of your keyboard? If so, it just might be the
Num lock, because my keyboard has the exact same
"1" just without the square as you said. Whenever you boot your computer the
Num Lock, (possibly the Caps and Scroll lock as well) blinks once (or a few times). I'm curious, but do you happen to have an
"A" and an
"Arrow pointing down" by the "1" as well? If so it is definitely the Num, Scroll, and Caps lock lights.
My cousin had a similar problem once. A virus burnt one of his memory sticks and whenever he boots his computer, the CPU will be on, but his monitor won't turn on, even if the power button is pressed, the light will just blink, but no display at all. Since he had two memory stick, he removed the burnt one, and his computer booted with no problem.
Here is what my computer's user manual states concerning memory modules:
If a blank screen is displayed after replacing or adding a memory module, the memory is installed incorrectly or it is the wrong type of memory. Remove and reinstall the memory.
The thing I don't understand is, that your monitor still remains blank even after you took out the new memory. However, sometimes, brand name counts. You could try to have it replaced. It could also be, that your old memory has been burnt, because even your original memory doesn't make your computer boot successfully anymore.
If you didn't try this already, what happens if you take out the old memory and put the new one in, on the same slot where the one was removed? How about switching the memory's position?Hope this helps.
Thanks.
