I was referred to from this topic: http://www.bleepingcomputer.com/forums/t/92475/infected-with-trojan-cant-remove/

I have done various spyware scans - Adaware, spybot, superantispyware - and with bleepingcomputer's help, we identified trojan malware with DrWeb. We used DrWeb and Combofix to try to remove it all, as well as regular hijackthis logs to mark progress. However, when run in normal mode, the screen resolution is stuck at 800x600 and won't change even if manually changed through settings. This causes internet explorer to fail for some reason, and so I have to launch the computer in safe mode every time, as I am now, in order to use the computer normally.

Did your video card drivers get corrupted?

Please try uninstalling the video card drivers, then reboot and reinstall them.

Can you instruct me as to how to do this? Would that really be the case even if the resolution appears fine in safe mode?

The video card drivers do not load in safe mode.

To reinstall....(MAKE SURE YOU HAVE THE VIDEO DRIVERS READILY AVAILABLE)

Go to Start > Control Panel > System > Hardware tab > Device Manager > Display Adapters > Select your adapter, press delete, then allow Windows to uninstall it. Then reboot the computer and when Windows Hardware Wizard pops up, install the video driver.

Go to control panel --> system --> hardware --> device manager --> display adapters.

Double click on the item(s) listed there, go to the "driver" tab, and click on uninstall. Reboot, bring device manager back and re-install them.

The good news is that the resolution in normal Windows mode is back to normal. The bad news is that I don't know how to reinstall the display adaptor driver, as it's no longer on that list.

:thumbsup: That is.... Very odd. Try re-booting and see if anything happens... to the list or the display.

Do you have integrated graphics or an installed graphics card?

Now I can't get on Windows normally, it says there's been a change either to hardware or software, so I'm in safe mode again. Still nothing under Display Adaptor.

Do you have integrated graphics or an installed graphics card?

I don't know, where can I find out?

Unless jwinathome figures something out this might be the 4th bad Mother Board case I've had today.... Bad day for computers I guess....

The port that you plug your monitor into....is it connected to your motherboard....or is it on a card that is then plugged into your motherboard?

It looks like you are gonna need to go the way of a system recovery or a system file checker. Someone should come along with those details.

When the screen that comes up with several choices of booting.. have you tried "LAST KNOWN CONFIGURATION"?

Recovery console - http://www.kellys-korner-xp.com/win_xp_rec.htm

To start the computer and use the Recovery Console

From the Setup CD-ROM

Insert the Setup compact disc (CD) and restart the computer. If prompted, select any options required to boot from the CD.
When the text-based part of Setup begins, follow the prompts; choose the repair or recover option by pressing R. If you have a dual-boot or multiple-boot system, choose the installation that you need to access from the Recovery Console. When prompted, type the Administrator password. At the system prompt, type Recovery Console commands; type help for a list of commands, or help commandname for help on a specific command.

As of now, I restarted the computer under "last known good configuration", and regular windows seems to be working. The display adaptor is still absent though. I don't know where the monitor is plugged in, the person who bought and installed this computer is not around.

It's connecting horizontally lower down the back of the computer.

So are you still having the resolution problem or not? I am sorry I believe I missed that.
