Please please could someone provide some help... I am having problems playing games on my pc. Basically, I have 2X120GB Seagate SATA drives, not in any raid config, but simply as drive C and D. Since January 2004 I have been running my pc this way. My pc is an Athlon 3200XP, Asus A7N8X deluxe mobo, 1GB OCZ Platinum ram, ATI 9800 Pro, Enermax 420W PSU. My problm is this: When I install Win xp pro with sp1, I go and download all updates. Then I install all latest drivers for all my hardware, inc DX9c and Catalyst 4.8 and Nforce 4.27 drivers. Now, my pc is fine, but the minute I install my Catalyst driver on, I hear a strange beep/whine from my hard drive. After inst the Catalyst drivers, I reboot as instructed and then get backj to the desk top. When I try to run 3dmark 03 or quake 3 for example, I hear the same beeping/whine from my hard drive and the game or 3dmark starts to load. When in the game or 3dmark, the graphics are jerky, pausing every 10 secs or so and resuming in a loop. All the time I am still hearing this beep/whine from the hard drive. I am starting to lose my head with this as I have tried my graphics card in my frineds pc and it worked fine. I then tried his graphics card (also 9800 pro, connect3d) in my rig and it gives the same errror as before, this beep/whine/squeaking sound. Can anyone suggest what this could be, short of me buying 2 new hard drives....I'm beginning to think that SATA drives are pants. They are not even a year old as I bought them in Dec 2003. PLEASE PLEASE PLEASE HHHHEEEELLLLLLLLPPPPPPPPP!!!!!!!!!!!!!!!!! EmissarY.
