Installed drivers on graphics card now screen won't work URGENT Please Help

[tl266]

Hi all

Got a serious problem that I need help with. Basically my pc has been randomly changing resolutions a lot recently and I tried to fix it by reinstalling the drivers. I checked online forums which suggested updating my graphics card to standard vga drivers. I did this but then the screen went black and I realised there are no vga ports on my graphics card. I have tried rebooting and running off of the integrated card but the screen always remains black and cannot recieve a signal. Please help

Before we can all help you, what are your system specs? Seems like your PSU might be the suspect of this problem you're having though. But let us know what your specs are.
