[Solved] MB & CPU Upgrade -- Do I need to reinstall OS?

Just upgraded my hardware from

Intel Dual Core, ASRock G-31 motherboard, 1 GB DDR2 RAM, 320 GB Hard drive

to

Intel Core 2 Duo, Intel DG41WV motherboard, 2 GB DDR3 RAM, 320 GB + 500 GB Hard drives

The system booted up fine after I chose "start windows normally" option. Uninstalled ASRock utilities and installed intel driver DVD that came with the motherboard.

Now everything looks and works fine -- things work much faster than I'm used to. The only issue is, there are a two beeps when the system boots (spaced by about 5-8 seconds) and that the system doesn't recognise the new 500 GB hard drive.

My question is, is it still recommended to re-install the OS (I have Windows 7 ultimate).

Also, what do I need to do so that the new hard drive shows up?

Thanks!

In Win 7, click on the Window button at the bottom left (used to be called the start button). In the 'Search programs and files' box, type 'disk management'.

Then choose the 'Create and Format...' option from the list.

Do you see the 500GB disk with unallocated space here?

You don't need to if everything's running OK.

As for the beeps, check this out:

Seems it's normal for that motherboard.

You didn't really change the chipset, so you didn't need to reload the OS. If you did it the way you did but changed from an Intel chipset to an AMD, then you would have had issues.
