Hi Guys,

Dell 1558 studio running ATI 5470. directx 11 . Win7 64bit. Graphics issues

When I run certain video files ie youTube the system black screens with power still on and I am unable to access anything, so end up having to reboot. It also ends up with a loud buzzing. This happens especially if I try to 'full screen' video. I have run passmark test on graphics with no issues and tried downloading latest drivers, but still no joy. Could this be a faulty graphics card??. System is only couple of months old and did not do it from new ( although this is a recon unit!!).

I have tried Dell tech support but no joy as yet...
Any info would be much appreciated.
