Hi. I have a little problem. Yesterday I was working on my computer after a some while my computer went to black screen. Then I restarted the computer by pressing the reset button. Now an error message "Windows could not load as the following file system32/drivers/pci.sys apperas to be missing or corrupt." is comming. I have tried to reinstall the OS (WIN XP Pro) after clearing the BIOS setup. It installed clearly. But after somtime it agin went to the previous state. I mean the error messaged appeared again. Please help me.
