Greetings to all and Happy New Year!
I'm running Windows XP Pro on a computer that is roughly 10 years old. We recently had a blackout due to weather and when the power came back my power supply in my computer was fried. I purchased a new power supply and installed it. Everything powered up but the system was behaving like it had some Gremlins in it. I now have everything back to normal except for the USB ports.
My motherboard is an ASUS P4PE with 2.4 GHz Intel CPU and 1GB Infineon RAM. I am currently running a completely fresh OS install on a spare hard drive I had lying around.
The problem is that if anything such as a USB thumb drive or external CD/DVD drive is plugged in to the 4 available USB ports on the back during boot up, the CPU Usage is shown to be 100% in the Task Manager at all times. Any plugged in USB device in also not accessible.
If I reboot without any USB devices connected, the CPU Usage is normal and almost 0%. Everything functions fine until I plug in a USB device at which point the computer completely freezes and is unresponsive. The only way to power down is to press and hold the main power switch.
Any input would be much appreciated.
I have read many reports of the CPU Usage being 100% even on much newer systems with running a newer OS. Is this a problem that can be fixed or is it likely some damage was done when the power came back up and the power supply blew?
The original power supply that died was an Antec TruePower 330. My new power supply is a Thermaltake TR2 430W.
