Help Sense "Loading..." and sluggish phone.

[Limerick]

Hello, I recently had to send in my Incredible for a replacement due to a faulty speaker component, and have had nothing but trouble with this refurbished Incredible they sent me in return. The problem I am having is Sense apparently restarting frequently when returning to the home screen. I have found no rhyme or reason as to when or why this happens, it seems to be random but is very annoying as it takes around 10 seconds to finish. I tried several solutions found in other threads that I will mention here:
1. Battery pulls
2. Factory resets
3. Root
I am currently trying out a solution provided to an EVO user here: http://androidforums.com/evo-4g-sup...ing-white-screen-green-htc-text-app-exit.html
involving app management and the app Spare Parts, and will report back on the results. I was also thinking of downloading the Incredible port of the Gingerbread update, but am hesitant to do so in case I need to revert and send this phone in for ANOTHER replacement for Verizon (which would be unlikely to help, I went through about 4 refurbished Palm Pixi's of theirs in the past with no luck, things were terrible).
Like I said the phone came to me clean, and has been wiped clean twice now via two methods of factory reset. No apps have been installed from the market, I have not touched the factory-state and am still having the issue.
Anyways, I would be very appreciative if anyone has any advice, thanks in advance!

EDIT: The Spare Parts solution did not work.

I'm having the same problem but on my Eris. Searched numerous threads but can't find an explanation or fix. Anyone?

Task killers tend to cause this very problem or anopther app that is a resourse hog. If it's not an ATK I would assume it's hardware. I know people that had to send in 4 or 5 refurbs in a row before they got a good one.

Thanks, I have no task killer so it's probably the hardware.

Perhaps use Launcher Pro in place of Sense and see if things improve. Only other thing i can think of is a fresh reload of 2.2. If there were some odd pre-existing glitch with the initial load of 2.2 on your phone, a factory reset wouldn't necessarily help the matter. Then again, hardware issue certainly can't be ruled out but these actions would make a strong case to reveal the most likely culprit if you didn't mind the effort.
