When i startup my computer i got 3 errors.

Qt-mt.dll failure re-installing may fix this problem.

Operalmg.dll failure re-installing may fix this problem.

Qt-mt.dll failure re-installing may fix this problem.

But when i tried to print i got the "Qt-mt.dll failure re-installing may fix this problem" again.

so i checked on google and i found a post saying to (Start\run\Msconfig) and uncheck all boxes except the ones that gives me a warning. i did so an rebooted my pc but when i tried to print i have no printers installed and neither i could install them. Abd i had no sound either so i checked the boxes again but same problems and with errors.

PLs help

I'd suggest uninstalling your printer and all of its software from Add/Remove programs.

Also uninstall Opera.

Reboot your computer and reload your motherboard drivers.

Reboot and verify that everything is working: audio etc.

Then try and reinstall your printer software.
