Computer With Weird Inconsistant Slowdowns

[Allan_vs]

Hey everyone,

In this holidays I've built my girlfriend a computer, specs as follows:

Ryzen 3200g
2x8gb 3000mhz
Radeon 6600
Motherboard is a BIOSTAR B450MH
500W PSU
960gb Kingston SATA SSD
Windows 11 Pro up to date

As you can see, its a more budget oriented build, but should pack some punch, since her monitor is only 720p and if it were to upgrade it would be to 1080p, and it does... most of the time.

Here the issue that we've been experiencing, for the first two weeks playing, everything went super smoothly, she was playing Marvel Rivals at high at 80 to 90 fps, finished Dredge (which isn't very demanding, but anyway), and also started playing The Witcher 3, that was running at a fine 60 fps in ultra (no ray tracing).
But as of last week the games started acting very weirdly, first Rivals had some heavy slowdowns downs to 5 fps, and it wouldn't go up. Then The Witcher had the same thing, in game it was stuck at 1 fps. The weird thing is that it is not consistent, sometimes I would restart the PC and it would run fine, sometimes it wouldn't...

Rivals tho, even when running "fine" would load everything very slowly, she would often be the last on the team to load and still have some slowdowns when something new loaded - which wasn't happening before (we were side by side in the first week playing and she would load basically at the same time as me)

What I've tried:
Radeon Graphics are up to date
Updated the BIOS (which was a pain but ok)
Reinstalled the game (Rivals in this case, but don't think that this is the issue)
The GPU temperatures are super fine running at a low 60 degrees Celsius, but I've not checked the CPU, don't think this is the issue because in The Witcher the issue is instant so I do not think is temperature throttling
Also checked the usage and it seemed normal? about 80% in the CPU and GPU with The Witcher

Some variables:
The PSU is a bit scetchy, I've bought the PC (except the GPU and SSD) from a friend so couldn't choose a better one, that being said, he told me that it was running fine
My house is 120V and hers 220V, the PSU is bivolt but has a physical switch for the voltages, felt kinda weird but idk
We briefly used the PC without a GPU, so could the APU drivers be interfering?


I really would apreciate any guidance, don't know what else to do and feeling a bit lost, and the GF is losing hopes in my PC building capabilities lmao

Make sure the monitor is plugged into the GPU and not the motherboard.

 

Did you update the SSD firmware?

 

Btw, the 3200G is a terrible bottleneck to the RX 6600 even on 1080p, and you are forcing the bottleneck even more by using a way lower resolution.

Either a 1080p monitor and a R5 5600 or an R7 5700X3D without a monitor upgrade are needed.

Thanks for the reply

No I haven't updated the SSD firmware, thats a good call.
And yes, of course, it is plugged to the GPU, as I said, there were a quite few session where the FPS were fine, completely normal.

As of the bottleneck, I agree, it is just that the budget was very tight, and my friend sold me his old parts for very cheap. Just for a bit of context, my girlfriend lost her house and all her stuff to a flood here where we live, the house was made out of wood so it had to be rebuilt, and the computer she had was also lost. So yeah, I know the CPU is not ideal but it was what we could afford at the time.

We will be upgrading the monitor as soon as possible tho, didn't occur to me that the lower resolution could be forcing it.
That being said, it doesn't explain the huge difference of performance in each session, the SSD firmware might tho.

Will be updating this after I try it, but if you have any other ideas I would really appreciate it.

Amd chipset drivers downloaded from AMD.

 

Replacing the CMOS battery. On a used B450 board the battery might have run out.

If the Bios was reset, a lack of XMP (RAM running 2133 interested of 3000) would loose quite a bit of performance.

 

The 6600 supports virtual super resolution, you can use that to play "1080p" even on a 720p screen.
