Hi Mpolo,
Just as a first try, if the problem started recently, and assuming it was working fine before, have you tried a system restore ?
If you are using a NForce2 chipset, you need to disable NVidia's IDE driver and use the Microsoft default driver, as itīs a known issue between Delta44 and this chipset.
Also, you may take a look at this resource, where there is a checklist about this problem:
