LG L5 restarts every minute

I don't know what I've done to my LG L5, but now it's just restarting and restarting. I've rooted my phone using adb and installed ClockworkMod recovery, but now it just restarts every time it loads into phone or into ClockworkMod. I really don't know what to do. Even if I get new ROM onto sdcard and try to flash my phone, it could randomly (in 1 min) shutdown, and I guess then I will brick my phone. So what should I do? I've tried to wipe cache/data/dalvik cache. At first I could get to my home screen and even work for a while, but now I can't even go to my home screen. It freezes on the boot logo and restarts after 1 minute. Even in ClowkworkMod recovery. Works one minute and restarts. Is there something that could help me? **Ok, so for now I've updated to cyanogenmod, thought it'll help, but no. It just keeps restarting, but now it goes to home screen again. So what to do? How can I update kernel or whatever I need to do?**
