Hi guys,

I’m experiencing some major hardware problems with my PC, and I fear it may have caused some serious permanent damage.

I’ve had zero problems with my PC since building it a few months back, but earlier I was just casually watching YouTube, and whilst opening a second YouTube video muted, the entire PC froze completely, also letting out a loud buzz noise.

I thought nothing of it, holding in the power button to turn it off, but after attempting to turn it back on again, it won’t connect via my hdmi to either my monitor or TV. The PC lights up and fan runs as it normally would, almost like nothing’s wrong, so I don’t know what the problem is.

Does anyone have any idea what this issue could be? I’m seriously worried.

Thanks

What video card/what psu/what cpu/board......?

PSU: be quiet 350W pure power 11.
CPU: AMD 2400g (which has the gpu intergrated)
Motherboard: Asrock B450M

Also, not sure if this is related, but I did overclock recently, but not by a high amount at all, and it’s been working fine two weeks since then.
 
Recent high ambient temps may have pushed something to the point of overheating so were you monitoring temps in general? Anyway on the evidence of buzzing we can only assume a power related failure so PSU, VRMs etc.

Either way you may have to swap components to isolate a failure.
 
Try resetting CMOS.

You can do this by using a screwdriver to bridge the reset CMOS pins whilst powering on PC, then remove contact when you see something displayed on monitor.

Another alternative way is to remove the CMOS battery (CR2032 coin cell battery) for a few minutes and then re-insert the battery (note the correct +/- orientation of the battery).

... I'd just add, remember to have the power supply unplugged from electric when you do this.
 
Was the noise from the power supply (or pc in general) or speakers? I bet it was speakers

Unplug everything not needed to get a pic on the screen test 1 ram stick then the other.. Try without a video card if you have built in gfx..

I assume you have no spare parts?
