Hello and welcome to Techspot.
Both minidumps crash at e10kx2k.sys. This is one of your soundcard drivers. They also reference ypager.exe. this is yahoo messenger. Both minidumps have a bug check of C2.
0x000000C2: BAD_POOL_CALLER
A kernel-mode process or driver incorrectly attempted to perform memory operations. Typically, a faulty driver or buggy software causes this.
Uninstall both your soundcard software/drivers, and Yahoo messenger.
Reinstall your soundcard drivers using the latest versions. See if your system is stable. If it is, reinstall Yahoo messenger, and test your system.
