I am having a problem with a sony vaio pcv-rx770 computer. The computer has a cd Rom, dvd/cd burner and a floppy drive. The computer will not start in normal mode or safe mode. I reformated and reinstalled XP on the hard drive. how ever if I put the hard drive in another PC it will start up fine and I also tried putting a hard drive with windows 98 on the sony PC and it started up fine. In my opinion there is something wrong with the motherboard. Maybe I need to flash the bios? I was also getting an error message "Line 3595 of the INF file \I386\txtsetup.sif is invalid" But the hard drive is fine because it will start normally on another computer Also I tried using another hard drive with XP on the sony PC and the same thing happened it won't start. It will just go to the F8 menu that ask you to start in safe mode or normal mode. This computer is for a friend of mine I have been working on it for 3 days but I am running out of solutions. Also If I chose one of the F8 menu options the computer will just restart and bring me back to the same point.
