I have the following config: CPU: AMD Athlon 64 3500+ RAM: Transcend 1 GB DDR 400 Motherbaord: Gigabyte GA-K8N51GMF-9 HDD: Seagate SATA 80 GB x 2 I download from the internet via torrent client Azureus from 2am to 8 am (happy hours. But for the past 2 days when I check in the morning, the task manager shows pagefile usage,RAM usage and CPU usage at 100%. And the computer acts very sluggish and stops responding. This usually starts about 2 hrs after I start the computer( I know this as my traffic manager reported speeds and the client stopping to download after that time). Though the antivirus is running(Avast) this problem occurs. When I intially start the computer the RAM usage is at 40%. What could the problem be? My inferences: 1. Virus or hacker attack!! 2. Heated up RAM or CPU (both 7 months old) 3. Heated up HDD(the HDD is barely 6 months old) 4. Program causing the problem(Azureus) Please help. Its URGENT!! Thanks.
