I've been using a GA-EP35C-DS3R mobo with a Q6600 CPU and Cooler Master eXteme Power 600w PS for the last 10 months. Just last week the fan on the PS packed up, so I got a replacement under warranty yesterday. Now, ever since I've connected the new PS, I'm getting this really LOUD noise from both the front and back panel headphone / line out ports. The noise is at the same loudness at all volume levels and only disappears when the volume level is brought down to zero. When I play an audio track, the noise overwhelms it completely, and all I hear is a faint scratchy audio track playing somewhere in the background.
Is this a mobo problem?
Has the on-board sound card failed?
Could it be a PS problem?
If it is a PS problem, will getting another PS solve the issue, or is the damage permanent?
I know I probably need to to take it back to the retailer, but given how little time I have, I thought I'd consult you all first.
Probably, when you screwed in the replacement PSU, the screws didn't give you a good 'case ground'; the screws should do it, but are sometimes occluded by paint or oxidation (not positive, but I think aluminum oxide insulates...); I always do this:
Hi guys, thanks for the advice! Apparently it was a motherboard problem, and I got that fixed under warranty. Since the PSU was suspect, I asked for a replacement, and got that too. Everything seems to be fine for now, but I'm touching wood and keeping fingers crossed anyway! http://img.tomshardware.com/forum/uk/icones/message/ico...
