iPod touch 4G reboots constantly

Hey,

I recently have gotten problems with my ipod touch 4G (32 GB, ios 6.1.3, EDIT :not jailbroken) , it reboots at random moments when in use. Just before rebooting it completely freezes. Sometimes it shows a blue, white or red screen, mostly just a black one(60% of the time i'd say). Afterwards it reboots( the apple logo on a black background) and sometimes it succeeds (slide to unlock screen is shown) and sometimes it doesn't and reboots again (black or colour screen and then again apple logo). Its can keep rebooting for long periods.
Sometimes it also crashes when hooking it up to the PC.

Problems started 3 weeks ago, and after a couple days of trouble I manually putted the ipod in restore mode (showing the usb cable and connect to itunes) and restored it. Afterwords I got the "setup a new ipod screen" on itunes and asked itunes replace my backup. It seemed to have worked, I got a couple of days without crashing and then suddenly he crashed again.

Now what follows are some thoughts of what I believe to have noticed:

-it feels like he crashes mostly when doing difficult thing( pop-up's when browsing, multitasking). I'd say memory intensive stuff.
-When the crashing begins, the more it crashes the less time there is between subsequent crashes (it gets less stable as crashing continuous).
-When I left it to rest a couple of days and used it afterwards it took much longer for it to crash again. It seemed like to have repaired itself, but not for long...

I also took some pics of the strange boot and freeze screens (sorry for the bad quality)

I really hope some of you guys could tell me whether this is a software problem (and how to solve it) or if it's a hardware thing and then I'll send it in for repair.

Thanks for reading this enormously long post

indeed, not jailbroken at all, sorry I forgot to mention that. I will try the DFU mode. But afterwords putting my backup back is not a wise idea?

Thanks

Bad news here, i tried DFU, but ipod kept crashing when connecting to itunes prior to shut-down. So I restored as I did before and then did DFU restore. It worked and I got my ipod setup as a new ipod.
Didn't work out do, it still keeps crashing, I'll be sending it in for repair.

Thanks for all the help !
