Now I don't know what seems to be the issue, and I'll admit the problem has existed before but I've been trying to play the Star Wars: The Old Republic Beta and it has never been this bad!
Basically my computer keeps freezing and if there's any sound playing at the time it creates a horrible buzzing/glitchy loop sound. I've read some stuff about it being driver issues but I've updated/downgraded etc and it hasn't worked.
I'm praying that it's something specifiaclly to do with this beta rather than hardware malfunction but any help would be greatly appreciated!
What are your temps at for your CPU and GPU? Have you tested your RAM (one stick in Slot 1, each at a time, and running Memtest on it)? Are there any other games this occurs on? Have you scanned your HDD for any errors?
