It's not exactly Hardware any more!
I have seen this issue before as well, where the Windows IRQ assignments are not stabalized unless you restart. The fault seems to be the actual Sound card (onboard) that is just not real compatible with this.
Sometimes the fix is to do a BIOS update (although you really need to know what you're doing here -> ie Not even the Motherboard manufacture guarantees BIOS updates won't stop your computer working all together !!!)
Another option would be to purchase another PCI Sound card, and then plug the front Mic Snd into that (instead of the Motherboard) But actually this is a bit extreme too (ie Sound and Mic actually work!)
You could uninstall sound Driver fully (from Add/Remove Programs) Then download the most up to date driver from the web.
Yep, Start with that one
