What problems upgrading Motherboard and Processor?

Hi experts, just need some advise, its been since win 2000 that I have built my own computer and I plan to upgrade one

I have an HP PC running a Vista OS.

I plan to just change the motherboard, memory and processor (AMD) to an

Intel base motherboard, with new memory and i3 processor.

Based on what I could see the PSU should be sufficient to what I have now (300 watts)

All my hard disk are SATA and connected and powered externally (Thermaltake)

Besides from driver issues, what other problems can I expect?

One of my biggest concern is the OS, would it ask for a new license and is there a way to just purchase an OEM license, so that I do not need to reinstall all my applications?

Any suggestions will be helpful

hmmmm... using a HP case can be done, but can be tricky. What is the HP model?

- make sure the psu is using standard pinouts and has the correct connectors for the new mobo (20/24 main -- 4/8 AUX, some new mobos even have 2 AUX plugs).
Depending on the video card, 300W might be enough, but I would really consider going to 400/450W, at least.

- you will probably have to get creative hooking up the Front panel connectors.

- is this an HP Vista install or a Retail version?
HP install is usually mated to the mobo, and is illegal to move to a different system. If it will boot at all.
If Retail, then no problem, just needs to be Reactivated.

- if you are getting the new stuff from HP, then contact them about moving the OS to the new mobo.

Model is HP Pavillion A6700Y

I will double check the PSU, but I believe the new mobo has the same connections

video card  I will use only the built in video of an H67 motherboard.

I don't use the front panel so not a problem for me.

Unfortunately this is an HP Vista Install,  I don't mind repaying as long as it is reasonable ($99).   But I would sure like to avoid reinstalling everything.

Any suggestions?

Looks like it isn't too old of a system (Socket: AM2+), so give the 300W a shot.

Not that familiar with Vista, so somebody else might have a better idea. But you might get away with a Repair Install with a Retail disc.
I seem to remember inadvertently turning a XP Home into XP Pro one time by using the Pro disc (but the Home code) to do a Repair.
If you have a spare hard drive, I would try it with a clone, first.

You can also try using the MS Transfer Wizard to move your Programs and setting over to the clean install.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Here is the steps for W7, but Vista should be about the same.
See if this will work for you with what hardware you have to play with.

you can always calculate the power you need - leave a margin at least of 50 W for additional cards and devices :

regarding the ram - use the largest ram size sticks the new board accepts; i mean better 2x2GB sticks than 4x1GB to avoid overloading the ram bus  (also for power)
the drive you have is sata, 500 Gb right?  if that's enough, you can keep it, but a 1 or 2 TB drive is only about 100$
you can also look for USB 3 which provides a nice speed increase...

I guess nowadays, especially for a windows system, changing motherboards would always mean a major reinstall.  I will do that.  Thanks

no upgrade path for software unless you buy a retail windows version for double the cost

bummer.   : (

Look around Ebay, computers shops, flea markets, classified ads, etc, maybe you can find a used copy for a decent price.
People dumped Vista when W7 came out, because it was flaky. Though the Vista SPs seem to have pretty much fixed that.
