CS:GO freeze + high pitched noise

[Gabb]

Happens about once a day but I'm still very concerned. Only seems to happen with CSGO, the game just freezes and a very high pitched noise was coming out of my speakers, only way out was to reboot. My gigabyte motherboard was flashing a 03 error which isn't even in the manual and I haven't found reference to a 03 error anywhere (I googled and checked multiple forums). I memtested my RAM for 9 hours with no errors. Some have suggested the problem actually has to do with my PCI soundcard X-fi extreme gamer issues with my mobo. How can I go about verifying or testing? I have updated all my drivers and the BIOS. Any advice or comments would be appreciated.

Computer specs are:
i7 3770k @ stock 3.5, Gigabyte GA-Z77X UD3H
Samsung 830 SSD 256gb and WD Black HD 1Tb, CoolerMaster HAF-X Case
Corsair HX 750 watt PSU, EVGA GTX 670 with 1.25 gig video memory @ stock settings, 16 gigs of Corsair Vengeance DDR3 Ram
X-Fi Xtreme Gamer card, Logitech G5 series 2
Corsair K90 keyboard, Dell 24" U2412M monitor

Pull the soundcard out and use the mobo for sound output. If problem is gone, then it's your soundcard.

We have a audio subforum too.
