Computer Takes 20 minutes to boot!

[/b]COMPUTER SPECS:

ASUS A8 Sli deluxe motherboard (Phoenix BIOS)

From the last week, my computer takes about 20 minutes to boot up to Windows. I cannot even get into Windows Xp until after 20 minutes. I found the event list and the following errors were recorded. I believe these are the errors that are cauing the long boot times.

An error was detected on device DeviceHarddisk0D during a paging operation.

The device, DeviceScsiiviVD1, did not respond within the timeout period.

DCOM got error "This service cannot be started in Safe Mode " attempting to start the service EventSystem with arguments "" in order to run the server:
{1BE1F766-5536-11D1-B726-00C04FB926AF}


Can anyone tell me what is the matter with my computer and how I should resove these error messages. I have already tried the Windows Knowledge base but to no avail.

Thanks

none

I think the problem is with the SATA controllers

How new/old is the mobo and HDD's?
