Windows 7 Windows 7 freezes randomly -How to restore windows registry

[thxbest]

My Window 7 64Bit freezes randomly. Although I do not know exactly what the cause is. I have noticed that windows always has "registry errors". I have repaired registry several times by using the tool "free windows registry" but NO success, keep coming back and the system still freezes randomly.
How can the issue be fixed?

Since the Registry is kept in memory during a session, you might want to run Memtest to see if your memory is normal. It may take an extended test to show any indications if something is wrong.
