I recently installed Windows XP Professional on a brand new 300 GB hard drive. Unfortunately, my computer is not running properly now. Various programs run slowly. My task manager is showing my CPU Usage at 97%, but the system idle process is at 90-99%. There are no Trojans, spyware, or viruses on my computer based on Pest Patrol and PC-Cillin. I have 1 GB of Samsung PC2700 installed in the motherboard, as well. What else may be causing this problem? I appreciate any help that can be offered.

To help anyone who may read this post in the future, my problem ended up being device driver related. The 97% CPU Usage was a result of hardware interrupts. Once I repaired Windows XP Professional, everything worked great.

I am having similar problems. Could you elaborate on how you repaired XP Pro for those of us not sophisticated in these matters?

To repair Windows XP, insert the CD for XP and reboot your computer. When asked to press any key to boot from CD, do so. If you are not asked, reboot and keep pushing F2 until you reach the BIOS screen. Change your boot sequence so your computer boots from CD first. Then restart your computer to receive the message to press any key to boot from CD. Press a key on the keyboard, and XP will scan your hardware. It will then ask if you want to install a new Windows XP OS or Repair an old one. Choose to install the new one. Agree to the license. You will now be asked if you want to repair Windows XP. This is when you select Repair by typing the R key.

Note: I have XP Professional. For home edition, I was never able to get repair to work. If repair doesn't work, follow the same process, only choose to install a new Windows XP OS and delete partition on the next step. This will reinstall Windows XP and clear your hard drive, so make sure your important data is backed up on another hard disk or on a CD or DVD. Hope this information is helpful.
