1. My computer no longer recognizes my sound card.
2. My computer no longer recognizes my network card.
3. Often (but not always) when I put a CD Rom or DVD data disc in either of my disc drives the computer freezes and I have to restart manually.
Can these errors really be due to the new hard drive? My last hard drive had some Dell sector on it, is it possible that is required to recognize the above mentioned hardware?
Please help! Thank you.
