About once in every 10 times my computer boots up with the wrong screen resolution.

I normally run at 1440x900 but sometimes it boots up at a lower resolution. It then rearranges al my carefully placed desktop icons for me and if I don't immediately restart, it saves the new positioning and low resolution permanently. If I restart without doing anything else, it boots up in the correct resolution and with all the icons in their proper places.



The error must be occurring early on because it also affects the Windows Login screen, so if I'm lucky I can spot the change their and restart at that point instead.

I've run an SFC check following the tutorial instructions here. The only problem detected is apparently a problem with "PINTLGNT.CHM" of Microsoft-Windows-IME-Simplified-Chinese-Core that is apparently referenced by KB948465 and has a "hash mismatch". I don't do Chinese, surely this couldn't be the cause of the problem.

I've updated the driver software and it made no difference. The display is "Generic PnP monitor on Radeon X1550 Series".

Any ideas?

Frustrating isn't it. I had that problem for a little while.

Are you using a standalone monitor or do you have a laptop? If it's a standalone, you could reinstall it from the cd that you got with it. However, if you go to Control Panel\Device Manager, Monitors, click on your monitor if it's shown. If not, I would reinstall it as above. If it is shown, click on it and, under the Driver tab, double click on the driver details. You'll probably see two drivers. Click on the one associated with your monitor. Only time will tell if it helps. If not, I'm sure you'll be back.

It's a standalone monitor (one of PC World's own I think, type X19W). It doesn't have its own software, it just runs as "Generic PnP" under the device manager using Microsft's own generic driver which the device manager says is up-to-date

You might try going to the AMD website and checking for a newer driver for your graphics card or try uninstalling\reinstalling the one you have.

Yes indeed, that's the monitor I'm using.

I've downloaded the latest drivers from the AMD website and it made no difference.

Try pulling the Radeon card and reinstalling it.

For me, the fact that it's changing resolution points to the graphics card and not the monitor. If you had another monitor, you could test this theory.

Yes I suspect the graphics card rather than the monitor, particularly as when in its lower-resolution setting, the icons that are rearranged stay that way and the screen properties show it as operating at the low resolution.

When you say "pulling the Radeon card" do you mean physically removing it, or making a software change? How wouldyou recommend proceeding with it?

I meant that you should physically remove the card and then reseat it. There may be detents you have to press to remove it.

Aha, thank you, I think it it was the word "reinstall" that had me confused.

I'll try that and let you know what difference it makes.
