I am running 64 bit Windows 7 on a desktop I recently assembled. I installed a sound card recently (SIIG IC-510012-S2 5.1 Channels 16-bit PCI Interface SoundWave) and found the drivers online for the sound card as well. The sound works well except about once every 12 hours (about twice a day) I need to restart my computer because of static-y, crackling sounds.
I leave my computer on in sleep mode and once in a while when I come back the speakers will just make a constant crackling sound over any normal sound it tries to play (I can hear it trying to play the correct sounds behind a loud fuzzy static sound). Last time when this happened, I plugged in headphones before I restarted to see if the speakers were causing the problem (these are relatively new as well) and the crackling noise continued to play on the headphones as well, convincing me that this is a problem with the computer.
When I restart, the sound works perfectly well for another few hours before the sound gives out again when I come back to the computer.
I have searched extensively online and I cannot find anything helpful about this issue. I would appreciate it if someone would have some advice for me. I will be around to provide any additional needed information that might help.
