[Jaydee100]

Hi,i have desktop Hp pavilion a6300f that didnt turn on at all the only way i got it to start was taking out the motherboard and doing the heating it up trick and it turned on.everything was working fine until my screen froze and i had to force shut down now when i turn the pc back on i cant get a monitor signal it keeps going to sleep, but my pc is turning on fine fans spinning lights on but monitor goes to sleep.

I tried the unplugging power cords unplugging vga cord no sucess so it cant be the vga cord or the power cords because they work fine tried on another pc tower and the monitor is working fine with another pc aswell
