Dissolving Picture

I've refurbished a creaky old PC and run the routine cleaning progs - registry, deleting junk files, de-frag etc.

Occasionally, the pic on the screen just dissolves into sparkling, moving pixels. It's back to ok after a re-start.

I'm sure the monitor is ok - it's fine with the other PC's.

Does anybody know of any particular causes of the dissolving screen?

Well something is still there as WC says
try
Control/Display /Screen saver

Obvious I know- but the best of forget....... there is sooo much to remember.
Failing that reload the O/S
try these thing be fore the ultimate -Reformat

or if this creaky old win 98, there is a routine that will pull the O/S and leave data intact
You will have to reload programs though.

The dissolving pic still occurs but less often. The PC is a Pentium 2 onto which I installed XP Pro. I have a separate screensaver so I don't think that's the problem.

A new type of freeze-up (with bigger pixel patterns and vertical black lines) now happens occasionally. Between the haze I can see a 'device failure' message with some error number.

I have a gut feeling that it's a low memory situation - maybe made worse by me trying to do too many things at once. Ummm.

I think your graphics card may be calling it a day

This is a long shot, if there is a PCI modem pull it out. and test

YK may have hit the nail on the head with the suggestion that the graphics may be calling it a dau with the device failure message.
However it may not be the the device per-se but the driver
Upgrading from 98 to XP is a total shift of all devices because of the new file system.
Some older devices have no drivers available for
NTFS[XP]
So check your driver status.
Is for for example the graphics card integrated with the Mo-Bo or a third party device?
In either case is there a Win 2000/XP driver for it?
Compatability is the name of the game.
It is increasing evident these days that 'upgrading' may be a 'fun' thing to do on a see what happens basis.
But for real practical purposes -replace is the order of the day

Thanks - I'll investigate the graphics card situation.

I couldn't read the error message for sure because of the fuzziness. It was possibly 880 or 881. I googled them and there was something about 'the modem'. I'm using a brand new external modem on this PC.

Is there any way to test the graphics card? I ran a Pitstop scan a few days ago and was given the following:-

Video - Matrox Graphics Millennium G200 AGP - scored as a 'Winner'

Video 2D

If you do not have the Driver for the Matrox Milleniuym- Check the web site
This is a pretty old card possibly no driver for XP.

OK - Thanks
