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. Here are my iMac specs Model Name: iMac Leopard 10.5.8 Model Identifier: iMac8,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.66 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 6 MB Memory: 2 GB Bus Speed: 1.07 GHz Boot ROM Version: IM81.00C1.B00 SMC Version (system): 1.29f1 Chipset Model: ATI Radeon HD 2600 Pro Type: Display Bus: PCIe PCIe Lane Width: x16 VRAM (Total): 256 MB Vendor: ATI (0x1002) Device ID: 0x9583 Revision ID: 0x0000 ROM Revision: 113-B2250L-259 EFI Driver Version: 01.00.259 Displays: iMac: Resolution: 1680 x 1050 Depth: 32-Bit Color Core Image: Hardware Accelerated Main Display: Yes Mirror: Off Online: Yes Quartz Extreme: Supported Built-In: Yes Display Connector: Status: No Display Connected Yes i have Leopard because i cannot get a copy of snow leopard anywhere.
