Unhappy Asus ME302C HD


I rooted my MemoPad with the direction from here and everything has been going fine for weeks. Now all of sudden my Windows 7 won't recognize it, the MTP drivers won't work either. Also I can't download anything from Google Store and my time & temp on front screen won't work. And all Asus say's is must be a hardware issue send it in on your dime. Can someone help with another solution?

Thanks in advance.
