I have Medion p4101D desk top pc with windows 7 .My PC started going slow occasionally some time ago, what would happen when I clicked the mouse for something to happen the screen would freeze and I would usually have to exit the screen by logging off. This sort of problem then started to happen more frequently until now the PC is unuseable. I cannot get F11 to take PC back to factory condition . I've started in F8 safe mode but this will not work.. Have used start up and repair: result failed error code=0 X 490. Left my PC on then went back later and it had on screen: American Megatrends then a few lines and at end it said : Port0 Device error F1 to resume
Any comments would be appreciated.
