iMac running slow and always frezzing

[Mechy123]

Hi everyone
i am haveing a problem with iMac
it has been running really slow and always freezing when i do simple things

I sometimes freeze randomly while i am just browsing on the internet
My Computer just freezes when i play games and such. I can't tab out or do anything but force shutdown by holding the power button.

My Computer is normally warm when im browsing but when i play games it is burning hot.

This has happened to me for a few weeks now it never happened before
I cannot do anything without freezing and such. It is really annoying

And when i force shutdown sometime when it freezes it will not turn on until i wait around 20 to 40 minutes.

I have tried Fixing my self by repairing my permissions using smcFanControl and cleaning my fan.

Im not sure what is the cause, i am assuming its the fan thats causing it to be slow, but it might be something else im not sure.

High temperatures are unlikely the cause of this freezing. Have you tried reinstalling Leopard? One question about the freezes; when it freezes, does the mouse still work but nothing else?

I agree with Intell.... High temps won't cause the freezing. Macs usually run pretty hot. If I were you I would try throwing all your important stuff on an external hard drive and maybe buy and install Lion? OR re-install Snow Leopard as Intell said. I'm no professional but that might work. If not, its probably a hardware problem. The geniuses at the genius bar will most likely fix your problem.

True but I've lost my copy of leopard and not likely to buy a copy of snow leopard anyway because my parents probably won't allow it and I don't know any apple stores near where I live...

Any other suggestions?

http://support.apple.com/kb/HT1379 try that. Thats to reset the PRAM, its not necessarily linked to your issue, but it might help.

You could also check see how much RAM is being used on a standard browsing session? Activity Monitor tells you RAM in/out/swap (this might explain the hotness) although to be honest the other posters are right, macs run HOOTT! To check this you could down iStat Pro (it also comes as a widget for dashboard)

Download Onyx, and go through the various bits n bobs particularly the stuff under the 'cleaning' tab.

Hope these bits help
