I also found the same problem. I have sent it to HTC support in Thailand. They cliam that it's "HARDWARE" error need to replace Mainboard.

guys, try this solution:
1.take out your memory card 1st
2.flash to another rom
3.flash back to the rom u which 2 use
4.install back the memory card
5.dont put your ringtone in memory card...copy it 2 phone dont share it in memory card...if can dont share any program in memory card too~
after i try tis, restart problem solved actually is the restart average decreased
but memory card problem still cannot solved....
try it and post your result here whether its work on your phone or not.....ty

the restarting is due to the little tiny button that is depressed by the battery cover. however, the cover doesnt completely press it down so when the phone is jerked around or somhting like that, then it restarts because the button gets un-pressed for a second.
to fix this, take a little bit of tape and make a small square out of it and just tape it over the button. this way, the button will be pressed a little more and should stop the restarts.
as for the microsd card not being recognised, the best thing to do is to simply restart your phone. this is a common problem with the startrek

Yeah, thats right zekky! People, read carefully zekkys post. I had a same problem half a year ago. And, after i have placed small square part of paper inside, phone stops restarting, and SD card also works perfectly.
