Hi there, I have a trouble when I'm installing a program. I'm concurrently installing a large program and surfing the Internet and listening to music. All other tasks run really really slow and seem not responding. A similar case happens when I'm extracting gigabytes of files from a compressed file (.rar). Everything slows down a lot. I don't think my computer cannot handle this or will find this demanding. Here's the spec: Mobo: MSI 880GMA-E45 (6GB/s) CPU: Athlon II x4 635 (quad cores, 2.9GHz each) HDD: Hitachi 500GB sata II (7200rpm, 16MB) RAM: Kingston DDR3 1333MHz 2GB * 4 (8GB in total) Power: Antec 450W 80plus (No add-on graphics card) I hope the above info can help. Thanks for reading my question.
