Just installed a Benq CD REWRITER into a compaq deskpro pc, pentium 3,\n500mhz. 128 ram. Running XP Pro. Now it hangs for ages during boot up, then\nstarts. Any ideas please? Also the bios doesnt seem to be saving any changes\nI make. I press F10, as it says to save changes, but next time I go into it,\nthey revert back to original settings. Thanks for any help.
