I'm having problems with a Toshiba laptop A75-S226 with an ATI Radeon 9000 video card. Initially, the video screen would be all black and you couldn't see the OS load on startup. At times, the screen would flicker and then go stable for a couple of minutes. When I received the laptop for repair, the hard drive was filled to almost 99% capacity and was very slow to load. Most of the files on the laptop were iTunes music files. To make a long story short, I off loaded the music files to an external hard drive and scanned for infections. I did find a trojan and some malware on the laptop and was able to remove them without any problems. The computer was also running on the bare minimum amount of RAM (512 MB) for this model.
I tried reinstalling the video driver on this laptop and this resolved the initial problem with the black screen and flickering. However, a new video problem surfaced after I reinstalled the video drivers and now I have a dark color band on the right side of the screen and a small fuzzy band underneath the taskbar. See attached image for details.
When I updated the video driver again, there was no change with the video band issue. I even tried to use ATI alternative drivers like Omega's Catalyst drivers but this had no effect too. You can see the whole desktop but it fails to fill the whole widescreen. Once in a while, the screen will fill the whole screen and the margin bands will go away but this occurs when I do one of the following:
Delete the video driver and try to force a generic driver in place
Change a setting in the BIOS to expand the screen under low resolution
Cleaned the computer for malware.
The first solution (deleting the driver) seems to work the most but I can no longer force WinXP to install a generic video driver because every time I delete the ATI driver now it reinstalls the ATI driver and the bands reappear. If I try to pick a generic driver from a driver list, it only gives me a list of ATI drivers. With each successive attempt, the OS seems to make the band thing more permanent. Also, I updated the BIOS and did more aggressive scans but this lead me to no where. Any suggestions would be appreciated.
