3 of the errors are fairly normal and are frequently seen on well-functioning systems. The Disk error is a concern tho'.
Because it's a disk error, the very first thing to do is to backup anything you can't afford to lose. If the disk is dying you may only have a limited amount of time to recover that stuff.
Once that's done, try running a diagnostic utility available from the manufacturer of your hard drive. A list of the more common manufacturers is located here: http://www.bleepingcomputer.com/forums/t/28744/hard-drive-installation-and-diagnostic-tools/
If the drive passes the diagnostic, go to Start...Run...and type in "cmd.exe" (without the quotes) and press Enter. In the black window that opens up, type "chkdsk /r" (without the quotes) and press Enter. The system will tell you it can't do it right now, and will ask if you'd like to do it on the next reboot. Answer Y (for yes) and press Enter - then reboot the system and let the chkdsk /r run until it finishes.
If this doesn't isolate the problem, then post back and we'll suggest some more diagnostics. I'm wondering about running a memory diagnostic and rebuilding your pagefile next - as the Disk error happened during a paging operation
