|Windows XP SP2|
Booting windows displays the starting screen, logo and finally the desktop off center, making the taskbar to disappear. About 30% of the desktop disappears at the bottom and about 10% to the right.
The screen resolution is properly adjusted and the computer works otherwise perfectly. Several activated system cleaning like virus/malware/Trojan programs show no infestation. Registry repair, defrag did not help. Neither did disk defrag or any further cleaning efforts.
As suggested at some help forums, I tried to use Ctrl Alt Del function to re-set explorer or explorer.exe, but this did not help.
Earlier, a restart automatically resolved the problem, but now it always starts with the problem.
Could it be a malfunctioning graphic card or something missing due to a cleaning process?
