Test post from Psion 7Book

I’m trying to determine if I can post to my blog from my Psion 7Book. It appears that I can’t from within Opera 5.14, I’m now trying the Psion Web application. Poor show if I can’t … It appears that I can post from Web, I can edit previous posts, but I can’t delete posts!

Had a good evening in with my brother, eating pizza and watching the ‘Weird’ Al Yankovich film UHF.

What is a graphics card?


My old graphics card is lying on the top of the PC case. You can see that the gold bit connects to the computer’s motherboard, while the blue socket is where you plug the monitor.

In response to the person who said to me, “Excuse my ignorance, but what is a graphics card? What programs do you use it with?” A graphics card (sometimes also called a graphics or video adapter) is the bit of the computer that you plug the monitor into. You can’t work without it. Well, you can, but it would be like working in the darkness.

In human terms, then, the graphics card is a bit like the visual cortex within your brain, which takes the information that it is fed and outputs it in a way that is most helpful to the user. On a computer the processor passes information to the graphics card which interprets that information and passes the image to the monitor. Your eyes take in light from the monitor, which is converted to an electrical signal which is then passed to the visual cortex which interprets it and you can see the image on the screen. Playing a very fast computer game, such as Battlefield 2 this all happens very, very quickly. Modern graphics cards are typically handing millions of instructions per second.

I hope that helps.

I have a cool PC

Cooler Master UV system fan

While I received an email last night from Dabs.com to say that my new graphics card had been dispatched and was safely in the hands of Parcel Force, ready to be delivered today … it didn’t arrive.

Not having the PC on 24-2 (since yesterday!) has meant that I’ve been able to tidy the house, clean the living room carpet, and go out for lunch with friends Craig and Jess. In other words: have a bit of a life!

But enough of that nonsense, back to important things. I bought a couple of 80 x 80 x 20 mm Coolermaster UV silent system fans today and fitted them to the inside of my PC case. I reckoned that if I’m going to be running more powerful components (graphics card and soundcard) then that means they are going to be running faster, meaning more heat. As it was I had only one external fan and that was already had the power supply to contend with. So I’ve added one fan at the front to suck air into the system, and one at the back to expel air from the system. While I was at it I also spaced the hard drives out a little more, as I was surprised at just how hot they were when I opened up my PC the other day.

Hopefully I’ll now have a much cooler PC. In every sense of the word.
