What kind of drive is it? A spinning (mechanical) hard drive? You may want to run disk utility to check it.
Also, do you have a current backup? If you don't, you may want to make sure your backups are up to date.

Yeah, it is mechanical hard drive. I did run disk utility and it says it fixed it and hard drive appears normal. The problem still persists. It is completely backed up so I am not afraid of loosing data.

Do you have the hardware test built in to your computer? That would be my next spot along with what Linc has requested above. The disk utility's hard drive test is pretty crappy, its really just checking the OS, the scan it does on the actual drive is really brief.
If you do have the hardware test, I would try that. It would give you a good idea on the hard drive. Start computer up and immediately hold the D key.
Also, how long does it take for this to occur? If fairly quick, you could try a safeboot and see if theres some sort of application thats hanging the OS up. Its a stretch but will give us a good idea of where to go from here.

When the problem happens, are you able to write to any external hard drives attached to the system? If the problem happens regularly, does its prevalence reduce if you boot the system into Safe Mode (hold the Shift key at startup)?

Good Idea. I will try that next time it happens. Actually it doesn't happen that frequently so I am not usually prepared. Maybe twice a week. But next time it happens, I will try all these tricks.
@Chocolame no hardware test built it. but I will try diskwarrior maybe.
