Ram test running with one test error so far.


A ha!


No need to run the test any further

even *one* error and the RAM should be replaced.

very likely nothing else worng with the machine


A cheap fix and maybe a time too put more in than originally!

You guys know a helluva lot more than I know, which is why I come here,
but...

A number of years back my beloved K7S5A box was giving me all sorts of
bizarre errors... **including the several seconds of reset time at the power
supply**. I finally started hosing OS files as, I think it was Franc
suggested, and had me ripping hair... the symptoms were all over the map. I
had replaced the PS and the RAM that gave me errors with no joy and became
convinced it was XP and did repair installs and finally spent $$$ on a call
to MS support.

The support at MS (surprisingly well versed and well rounded technically as
opposed to earlier encounters) suggested I look over the caps with a
magnifying glass as some of you have suggested. I found two caps, IIRC,
maybe more, that were not brown but that had bulged a tiny bit and separated
at the center of the criss-cross. Swapped the board with all the same
components and all was swell again. I even went so far as to put the
supposed bad RAM back in and it tested just fine.

So... my humble experience is... the bad cap thing can in fact show RAM as
bad when it is not. Don't ask me how because I don't know. I can sympathize
with the OP's frustration if RAM swaps are giving him a confusing result if
there are bad caps... *especially* when the tests support the theory of
replacing them.







Looks like a tough problem...
since the screen moves the same whether you scroll down or page
down...

No, the video/screen effect is quite different. All kinds of
things/pixels are going off the screen and all kinds of things/pixels
are crawling/scrolling onto the screen when you scroll. When you page
the entire screen content just 'flips'/transitions all at the same time.
Try it.

it looks like it may be mouse related or a possible problem with the
PS/2 port.

I'd try a different mouse...and go so far as to trying a serial or USB
mouse

I really don't suspect anything with the mouse. If I weren't running
the memory test right now I would figure out how to keyboard or arrow
scroll a page and maybe trip the error without using the mouse.
