Hello, my computer will turn on (Fans start and lights turn on inside the computer) however nothing is displayed on the monitor and there is no start beep like there was when it worked. I have tested the PSU, the video card, and the RAM. Nothing i do seems to work and i need to know if i should buy a new motherboard or a new Processor. I have also cleared the CMOS and taken the battery out.
make sure you have all the power cables connected to the mother board, make sure all the components are plugged in, if that doesn't work then you have a faulty video card since there is no display or the power supply doesn't have enough power to for all the components. There is no way it is your motherboard since the power is running through it to go to the fans and you said those are working
Thanks for responding! All cables are connected to the motherboard and all components are plugged in. The problem is not the video card because my friend tested it, and i have tested the powersupply. But yeah the fans work fine.
I used to have this problem, and do every now and again.
Try unplugging all wires (USB, screen, etc) except for the power cable, turn it on, and off, unplug power cable, plug all cables back in. Otherwise, I used to disassemble my pc, and assemble it again and it would work.
