AsRock B550M Pro4 Red light for CPU and DRAM

Make sure you connected all the power cables correctly. The CPU needs to initialize
before the RAM can so if both lights are on then the CPU did not initialize.

If the system was working in another case then the most likely cause is you forgot
to connect the 8 pin power cable or connected the wrong one (should be a 4+4 not
a 6+2)

Hello, I have the same problem but my PC was working fine until I turned it to sleep mode yesterday, then after 2 hours the fan was on the power light and everything but nothing else would come on.
I just opened up the case and these two lights are red.

I didn't change any cabling, any idea what I should do?
I have this motherboard for about 6 months

Sleep mode can sometimes bug out and cause the system to enter an invalid power
state. Usually when this happens all you need to do is disconnect the power from
the wall, press the power button then let the system sit for 10 mins or so.
Then reconnect the power and power up the system. I suspect reseating your RAM
didn't do anything but powering down while you did it resolved the issue.

It shouldn't cause any hardware damage, it could be that you had a power fluctuation
while the system was in sleep mode that caused an issue. I have had that happen
on my own systems a few times, particularly when there are electrical storms in
my area.

Try disconnect the system from power, pull the CMOS battery then press and hold the
power button for 3 - 5 seconds to fully discharge any residual power from the board's
capacitors. Leave the system like this for an hour then reconnect the battery and
power and try power up again.

Load shedding can fairly easily cause damage to components. What happens when
they turn the power back on is what is referred to as "inrush current" where there
is a brief spike of high AMP power before the voltage and AMPs even out and stabilize.
This can cause serious damage to a board, particularly if the PSU is a cheaper
unit with limited protections in place.

If a power protection on the board was triggered and didn't clear then the steps
I mentioned above should resolve the problem. If not there may be damage to the
system.

I?™m having a very similar problem, where I am having both the CPU and the dram Lights on Tried everything I?™ve tried Receding my 8 pin, 24pin, GPU, CPU, ram even my sata cables and it fixed nothing and This happened while I was playing overwatch 2 My screen randomly went black, and then those lights were on and this happened will I was live streaming on twitch
