Self-built PC: No picture, no USB

[Wenzel Zerbe]

For the first time I assembled a PC - with a Ryzen 5 3600, B450 motherboard, temporarily a GTX 660 and with a power supply from Be quiet!  - and it doesn't work.  When switched on for the first time, everything worked great;  the BIOS could be called up without any problems.  Then I tried to overclock inexperienced and increased the CPU speed by 100 Mhz.  After the restart it didn't work anymore.  Everything seems to be running, all the fans are turning and all the lights are on.  However, there is no picture and the connected keyboard and mouse did not light up and were not recognized.  USB sticks won't either.  When i put in  an older mouse, it glowed.  I checked everything again, all the cables are where they belong, HDMI in the GPU. What am I supposed to do?

Reset the BIOS (aka "Clear CMOS") per instructions found in your motherboard manual.

Were you able to do a CMOS reset on this system yet?

If you are not familiar on how to do that, please mention the specific motherboard type (i.e. MSI B450 Tomahawk, ASUS B450-F, etc. the model number of the motherboard).

Typically the CMOS (the BIOS) is reset by holding something metal (like a screwdriver) on a header and turning on the system, but the exact method may differ from one board to another

Or just yank the battery out. Most motherboards have their CMOS battery open and all you need to do is to pull it out, Intel made a guide on it which is handy too:

It is a B450M Pro VDH Max. I'll try to do the reset.

This is how to do the reset on this motherboard, for reference:

either-or method would be usable, personally I prefer the jumper method, because that is what the manufacturer line out in their manual (so it feels like the more 'guaranteed to work' method).
