    That solution doesn't help me.

    The hard-drive boards he replaced did not come with any CD.

    Is there another solution you can think of?

    The hardrive he replaced did not come with a CD. That solution does not help me. Is there another way to fix these 2 drivers? Should I order the recovery kit from HP?

Here first of all to observe is that which hardware you had added recently and then you particukarly install the drivers for that device.if again u are able to see the question mark symbol then you must reinstall the motherboard drivers....

if u r not given the drivers for the new device then you can get those drivers ffromm internet and install them by browsing the driivers from your system

POST Beeps.

HP Beep codes are listed here: None of them matches your description, so listen again and see if the pattern matches any described by HP. Have you tried the monitor on another computer? Did you connect to the onboard graphics connector? Look for any loose components, especially memory.
