Windows 7 Crashes during CHkdsk

I own an older Win 7 X64 PC. The thing runs fine without problems except when I try to schedule it for a disk error check (Chkdsk) upon restart? When I schedule that the PC is able to reboot, start up and go into error checking and finish part 1, but when it gets to part two it crashes about 25% of the way through it? When I say crashes, what happens is the monitor light goes from blue to amber and the thing just sits there like it went to sleep. No matter what I do it won't come out of this? If I hit the restart button it starts with three beeps and just sits there. I have to completely shut the PC off, let it sit there for a few seconds then restart it.

Once I restart the PC I have to cancel out of the disk check or else it will go through the same thing again. Once I cancel out fo the disk check it boots up and runs fine without any problems that I'm aware of?

So my question is this: How do I get this PC to run a disk check (chkdsk) all the way through to completion without it crashing? Should I just put the thing back to a version that was working (from backup) or is there a good way to fix this?

Thanks
