Re: system gets stuck with 5500FX
I had random beeping sounds after installing a new FX5500, later i found out that my power supply wasn't stable so i change it. Now its gone.
Try your card on your friends PC and if theres no problem then check what PSU he's using, or you could try swapping his PSU with yours and try it out?
*Be careful while handling internal PC components, if not sure get professional help.*
Hope this helps.
