Hi all, I'm at my wits end while trying to upgrade to Windows 7. I'd previously had Vista Home Premium 64bit installed, and everything was fine apart from loading speeds, odd crashes etc. I bought a student edition copy of Windows 7 Professional (64bit) from software for students.com. I did a check to see if the pc was good to go with a windows 7 update tool, and had no errors. Also checked if it was compatible going from home premium to professional. And all was good on that front. Ok, so i bought the bootable disk, and put it in the pc ready to install. All goes well until the last part where it copies over files from previous windows, and then the display goes from normal to a green/yellow. White is no longer white, more a yellow, and all reds and blues all become a wash of greeny yellows too. The installation completes, and no driver updates for either graphics, display or windows updates remedies this. I've tried printing screen and emailing to my iphone, and the display is perfect! I've reinstalled twice, and again all colours are bang on until the same point in the install, and then it reverts to the yellow/green display. I've now just tried a clean install deleting the old partition, and surprise surprise its gone green/yellow again. It can't surely be the monitor if all boot up screens and during installation is displayed correctly can it? Same goes for drivers? Searched high and low on the web and this forum for anyone experiencing the same problem, yet nothing is available. Any help or guidance would be extremely welcome, Many thanks.
