I have an Old Dell Optiplex 755 SFF with an Intel Core 2 Processor (windows 7). Now This can hold a PCI-E x16 port. Now I got an ATI Radeon HD 5450 low profile. I plugged and played and it fits without a hitch, the software installed too! , now for the graphics well... It doesn't really work at all as it seems to freeze at the moment that it loads on the windows logo. It loads into safe mode so I'm not really sure what the problem is. Any ideas, I read the dell forums and they should be somewhat compatible... with the specs so I'm at a loss here. and I am a novice here. Ideas?
Edit I have tried to reset the cmos,no luck there. I have tried to move the ram as well. nothing big happened.
