Unhappy [Q] Sero 7 Pro Need Fastboot drivers

I have been using the rooted CWM on my SERO 7 PRO for 2 months now Recently my wifi kept shutting my sero dow neverytime i turned it inon.

I recovered it once with Recovery in the CWM but last night i tried to recover and it rebooted into the HISENSE logo with a battery uncharging.

It wont do anything when i try to Power on Volume up (No fastboot message). I have a Computer and USB cord, can someone guide me or help me get it running or I can I fix from my running computer? Thanks all
