Hi!

I have exactly the same Motherboard and processor, and I killed 256Mb of DDR RAM after about 3 weeks regular use.

I’m not an expert so I don’t know exactly why this happened, but here is my best guess. I was having all sorts of wierd driver issues on start up that I was putting down to updating my video drivers, but towards the end I got stuck into a cycle of rebooting – windows starting but not recognising any drivers – having to install all drivers – requiring a re-boot and then starting the process all over again. The terminal stage of my problem was when the HD wasn’t even recognised at start-up. That problem gave me days on end using a friends computer for a hour or two at night looking for help! Eventually, some message board pointed me to check my RAM and whn I removed one offending stick – instant cure!

I don’t know how many sticks of RAM you have, but to troubleshoot, remove them all and replace them one at a time, with only one stick present and see if the machine even POSTs. There is a section in the manual on the beep codes for bad memory. I tried a memory tester in advance of this step, I forget which one, but it didn’t pick up the errors! The bad stick on its own shouldn’t allow a good POST.

I would also be very concerned about the temperatures you are quoting for the CPU and motherboard. I know that they do not give alerts on the ASUS utility provided, but I think I picked up on another newsgroup that athlons shouldn’t go much above 50 degrees C and that motherboards should be around 30 degrees C.

I attributed my dead RAM to heat and installed an extra case fan. It makes the machine a noise monster, but the temperatures did come down from late 60’s to about 55 for the CPU and high 30’s to 30 for the Mobo on the ASUS utility. I haven’t had a problem since.

The memory test as above will take max 20 mins. Do it before you try anything else.

I think you are trying to make this more difficult that it actually is…. or I could be missing something.

I can think of at least 3 ways of do this:
1) Get a tape and measure it. Possibly the only way to confirm that your assumptions regarding the 4:3 ratio is correct.
2) Algebraically using pythagoras. Excel sheet attached. (It can deal with ratios not exactly 4:3 if you can measure them)
3) Trigonometrically, i.e. using tan, sin, cos…. I can’t remember which, math classes were way too long ago. The assumptions regarding the ratio of width to height are critical to the accuracy here.

Don’t forget that the actual size of the pixels could still be different if the gaps between them differ in size.

Once again thank you Hans for the trouble!

I tried all the troubleshooting steps except the rebuilding of the registry key. I’m on a corporate network and I don’t have access to regedit (blocked for security reasons).

The problem is still there!

Another interesting aspect is that the behaviour is normal when I click in the blank spaces in the vertical scroll bar, it scrolls exactly one screen, yet still the page down key gives only a half screen or less.

Andrew obviously also has the same problem.

Thanks Hans for your quick reply!

I cannot report success however.

ctrl-pagedown worked perfectly all the time. My wheel mouse works correctly in word and other applications. pagedown alone however only moves the view and insertion point less than half a page.

I followed your steps exactly and re-assigned the pagedown command to the pagedown key, but the behaviour is still the same. I read to the end of the screen, press the pagedown key to get the next screen and I lose my place as the text only moves half way up the screen and I have to search in the middle of the screen to find the unread text. Very frustrating when you are accostomed to continuing at the top of the screen with the new text.

This is on a relatively old PC recently assigned to me at work, and has never worked correctly while I was using it.

It seems to work fine in normal view (moves fullscreen), but not in page layout view (half screen).

It is frustrating, so any other ideas would be really useful.
