Unhappy [Q] Help. GT-P7500 shut down, not booting.

I was using my Galaxy Tab and it turned off by itself and now it won't turn on I tried turning it back on but it won't work. I also tried connecting it to a power source but still, It won't turn on. It is rooted and running CM 10.1 Nightlies. If you need any information about my tab just reply. Thanks in advance.
