This started three weeks ago. The first two times, there was a blue screen explaining that Windows had shut down because of an error. After those incident, PC just automatically reboots. Every after reboot, I could not connect to the internet without reconnecting fast ethernet NIC. Usually, PC rebooted when I accessed my yahoo account.

Today, within one hour PC rebooted twice. The last time, there was a message again and a technical information. It was doing a memory physical dump.

Technical information:
0x00000068E (0xC0000005, 0x80566168, 0BAD21C78, 0x00000000)



Can somebody help me? i'm getting worried because I can't figure out what's wrong and how to solve this. Is it something to do with bad OS?
