Card didn't work while fan is running


That is a really low end video card. The same card is available for $10-30 on bidding sites. Get another one or upgrade to something with more horsepower if you like games or watch video. Just make sure your motherboard will support the new video card. THe one you looks to be a standard PCI (older format).

I am using a casio calculator model fx-991MS and it keeps giving me wrong answers like if i say 5/10 i get 500 and the letter M at the top of my answer. i have an exam tomorrow please help


This is valid for the Casio FX-991W but I suspect it works for the FX-991 MS.
The Engineering Mode is ON so that all results use the Engineering display. When you divide 5 by 10 the result in engineering notation is 500 x10^-3 or 500 milli some unit, hence the little m after the 500. Other symbols you might have are k for kilo, or M for Millions, G for billions, mu for microns, etc.
In Engineering notation, the exponents are always (positive or negative) multiples of 3.
o recover the normal display, you must turn off the Engineering Mode.
Press the MODE button repeatedly until you reach the EngON EngOFF page. Select 2:EngOFF.

I have to buy Casio FX-991W Plus. No one has it. I checked eBay and the Casio web-site. I need that one. where can I get it from?


Hi,
If you cannot find it, buy an FX-991ES. It is solar-powerd and it has the natural text-book display, which is a novelty in calculators.
I know that Staples carry the FX-991ES.

Hope it helps.

I have a blank screen


Glad you got it fixed. Next time something like this occurs, try searching the forum of your distro (or the Ubuntu forums as they seem to have just about every error ever listed in there) as you will usually find the answer faster.
