Ok well I recently installed Win7 on my computer and I had to find a new audio driver as the one I had before was not compatible with Win7.
Downloaded a new one from Realtek and I installed it and it worked fine.
Till I turned my computer off.
So it seems every time i reset my computer it uninstalls my audio driver.
It is on-board audio.
Mother Board: ASUS K8V-VM
Chipset: VIA K8M890CE + VT8237A
Any questions that might help you help me are MORE than welcome!
