No Signal to Monitors- even with new replacement parts

gabchang

Hi there- been having this issue for a few weeks now. Basically, whenever I had to shut down and power back up, my monitors would not detect any signal. I would restart my computer a few times and then the issue would go away. The monitors were connected to the GPU, via DisplayPort.

However, yesterday, the issue persisted; I did some troubleshooting (checked cables and monitor, even on a different laptop) and no luck. So, I went and bought some new parts yesterday, and still the issue is happening.

Any tips/help? Everything seems to be powering on. Just no signal detected on the monitor/s.

My old build: i7-6600k, Asus 1080 TUF, Asus Sabtertooth TUF motherboard, Corsair Vengeance LPX 2133, WD SSD (has OS), WD SSD and Corsair PSU

New build*: AMD Rysen 7 5800x, AMD Radeon 6700xt, Asus TUF B450 Plus II.

*I kept the RAM, Storage, and PSU from my old build- all technically compatible, according to guides.

Just to add a small detail: With my old build, I would have to leave my computer on sleep mode, otherwise the issue would occur.

I'd call that a cold boot issue. It only happens when the system is 'cold'. Memory and PSU are very likely and they are two components that you kept.

Keep in mind that generally with Windows 10/11, shutdown is S4 rather than S5. Try this. The next time you leave the PC off for a while, flip the switch on the back and cut power. See if the issue still exists. Lets figure out if it's really cold boot issue, or more of a long hibernate issue.
