Hey guys i need help , so i've got my new gaming pc 2 days ago. I payed the store (azerty.nl) to also do montage/build it (i was scared that i might break something ), i only had to connect the 2 extra case fans on the side panel to the mobo , don't think i moved anything maybe the GPU , they even did cable management so it's all good but when i tried to boot the pc i don't get any video signal to my monitor. The mobo shows the A2 error which stands for "IDE detect" error. I don't know what to do , i tried to reset the CMOS and repositioning the RAM but still didn't work. I tried with a brand new HDMI cable on the GPU slot and then an old VGA cable for the integrated gprahics from the mobo and still didn't work. I tried to unplug the DVD writer (read somewhere it might work). The monitor isn't the problem since i was using it with my older PC. Please help me.
