Multiple Errors - Running Slow to Trouble Loading

Yesterday (Sunday, April 4th), around 1pm or so, I was playing World of Warcraft and was switching to a different window. It began to run really slow and became unresponsive, so I shut it down. When I tried to start it up, it was running really slow and running into multiple problems. When I tried to log in it eventually came to this:

"The instruction at 0x0000000077011E00 referenced memory at 0x000007FEFB78B00C. The required data was not placed into memory because of an I/O error status of 0xc0000185."

After a couple hours of trying to get it to work, I came to a similar error:

"The instruction at 0x00000000772B1E00 referenced memory at 0x000007FFFB6CB00C. The required data was not placed into memory because of an I/O error status of 0xc0000185."

Could something be wrong with the hard drive?

More likely a memory overflow. If it doesnt happen again forget about it
