Hi Guys, Currently I am facing one problem with my computer. The configuration of my computer is Gigabyte GA-8SMML motherboard, P-IV, 512 MB RAM, NVIDIA Display Card and 2 Hard Disks of Seagate (40MB & 80MB). I have Win XP SP2 (default OS), Win 98SE and PCQ Linux on C,E and on some free space of my computer. All these three OS' are on the older hard disk. Following is the problem of my computer: As I mentioned above, I have two hard disks. The second hard disk of 80 GB capacity was installed recently. The older hard disk is of 40GB capacity and my OS reside upon the older one. Both of the hard disks has 4 partitions. When I attempt to scan all drives by Norton Antivirus 2005 my system gets hung during scan of the new hard disk. I have PCTV TV-tuner card on my computer on the same partition of Win XP (E-drive). If I record a TV program on a separate drive on a separate disk then my system gets hung immediately after the recording is started. May anybody kindly suggest ways to solve my problems.
