This seems to be a common error seen with HP printers as well as desktops. Since there is no flashlight icon seen in the error messages the question here is are you running an HP model? The problem seen with HP printers requires first shutting down the system upon removal of the present drivers and then disconnecting the printer, printer/scanner. or printer/copier/fax. From there you restart and install the correct drivers and then reconnect the hardware.
If you have an XP installation disk you can try the system file checker to see if that will correct this. With the cd in the drive you type "sfc /scannow" at the Run prompt and press enter. The utility then verifies and repairs or replaces any system files found damaged or deleted. Another step to take is run a good antivirus program since the svghost.exe file is named. Often a virus or anothe type of malware will pose as a system file.
