So I have a MacBook Pro that is now 3 years old. I upgraded the OS to Lion back in July. It had worked fine until a week ago when my laptop started to freeze a lot. In addition, there are many different errors:
- I cannot save Word documents due to full of memory error
-Keychain cannot be found
-Cannot record using PhotoBooth
-Cannot uninstall programs
-Mail sometimes do not work properply
-Firefox says that a copy has already been open though there was none
-Wifi does not connect to network (signal is present) after turning the laptop on from sleep
-Black screen after open the laptop (from sleep mode).

I have brought my computer to Apple Store and they said there was nothing wrong with my hard drive. They told me to reinstall OS Lion, which I have already done. However, these problems occur again. Therefore, do you guys know what is going on ?
