Black screen

[williamhance]

Hi,
I’ve recently pretty much rebuilt a whole new PC, replacing everything except disks and PSU.
I’m not great at this stuff, I rebuilt it with my dad and it took us a while but we got there.

I have a problem that has started occurring maybe 3 days later, after taking out an M.2 disk because it was the wrong type, where my screen randomly goes black.
The whole thing goes like:

• Screen freezes for about 1.5 seconds
• Screen goes black (most times, sometimes it just freezes on what I was at)
• I can still hear my friends on Discord but they can’t hear me.
• If I’m playing a video on YouTube, I can hear it for about 5 seconds then it stops.

This happens fully at random but somehow happens less if I’m playing games. Copy and pasting this in Notepad right now because I just lost the other version I was typing.
It doesn’t constantly happen, it happens under no pattern. Can happen not at all one day and can get bombed with it the next day.

I have tried to:

• Uninstall drivers with DUU
• Reinstall Windows.
• Re-seat GPU and RAM
• Reset BIOS.
• Turn down GPU core and memory clock
• Increase fan speed

SPECS:
CPU Intel Core i5-14400F
Graphics Card NVIDIA GeForce RTX 4060
Motherboard MSI Pro B760-P DDR4 II
Memory CORSAIR VENGEANCE LPX 16GB DDR4 3600MHZ (2x)
SSD Micron_1100_MTFDDAK256TBN (256 GB, SATA-III)
HDD ST1000DM010-2EP102 (1 TB, 7200 RPM, SATA-III)
PSU Corsair 450w (don’t know the specifics but its almost 5 years old)

My guess is the PSU but I don’t want to go spending money for no reason.

Edit:
Only restarting fixes it. The monitors either freeze or lose signal (what I mean by black screen).

PSU Corsair 450w (don’t know the specifics but its almost 5 years old)

You have a 99% top of the range rig there but unfortunately the other 1% is a junk PSU when what you actually need is a PSU that eclipses the top of the range standard, the PSU even if it was of the required spec it is 100W short of what Nvidea state here for your GPU which is 550W.

You need to get yourself a 550W or above Gold efficiency rated PSU from one of the following, the Corsair RM range, EVGA, Seasonic or Super Flower.

The RAM is not appropriate for your CPU, Intel state here up to DDR4 3200MHz/MT/s and if you have DOCP/EXPO/XMP enabled the RAM will get auto OCd past what the CPU can handle and the PC will become unstable.

You should also make sure that the Windows Power Plan is set to Balanced and not High Performance or Ryzen Balanced.[/color]

The RAM is running at 3200MHz so it should be doing fine, no? I have XMP enabled.

If the RAM information you provided is correct and you have XMP enabled it is not possible for your RAM to only be running at 3200MHz, as to why is explained in my canned info below;
Modern RAM has two speeds, SPD (serial presence detect) and XMP or similar such as EXPO, SPD is what the BIOS detects on boot which for DDR4 for example is most often 2133MHz and XMP which when enabled will set the RAM to run at the maximum speed that it is capable of.

Unless manually OCd to 3200MHz your RAM will run at its SPD speed of 2133MHz when XMP is disabled and 3600MHz if XMP is enabled.

You do not mention having checked that the Windows Power Plan is set to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues and a weak PSU such as the one that you have will get hotter and weaker the more that you use it, snap, crackle and a loud pop will be heard at some point if using anything other than Balanced.

You are welcome btw
