My friend tried to overclock his AMD FX4100 to 5Ghz by changing the multiplier in the bios.
Silly I know as I told him 4Ghz as i'd had it running at that fine.
Anyway the computer didn't boot up. When he turns the computer on now the hard drive light flashes but he gets no picture on the screen. I told him to clear the cmos but was wondering if anyone had any thoughts or ideas. His motherboard is a Gigabyte GA-970A-DS3.
Any ideas or help would be greatly appreciated guys.PLease help if you can
Pull the battery out of the motherboard, let it sit for like 60 seconds, put it back in and retry would be my best bet. Hopefully he didn't cook anything, but most likely it just fails to boot since its way to high.
Pulling the battery and unplugging the system from the wall will drain the power resetting all BIOS setting. For good measure, press the power button as it will try to start the computer but drain any power left in the capacitors. There's usually also a jumper that will reset the BIOS. Trying to overclock a CPU shouldn't damage the graphics card. A symptom of a failed over clock is getting no video signal. Resetting the BIOS should make everything work again.
