Where is my bottleneck?

[loganc123]

Hello guys, I have recently been having some issues with running most games, where my FPS will drop to around 12, however 15 minutes later will go back up to 100+. During the low FPS period, my CPU Is underutilized. I believe that this is due to my PSU being faulty but just wanted to get another point of view.

*Also - is there a way to test if my PSU is faulty? I checked my 12V rail and it was reading 8.9V using Speccy. Could this be faulty?

Here are my specs:

I'd suggest you download a software to keep your PC components usage in check and see if anything is being bottlenecked. I use MSI afterburner app on my phone for that.

Speccy probably isn't reading the sensors right,otherwise would that pc just not run.

You might try the next see what that gives for sensor readings,

download hwinfo32,
install and open it,
check "sensors-only",
click "run".

don't run them tools simultaniously.

Also look at the temperatures. High temps might be the cause too.

 

[loganc123]

HWInfo Shows 11.96 on the 12V. Temps don't seem to be the issue, temps are around 45C on GPU when the FPS randomly drops. Any other ideas?

 

[Vic 40]

Was more concerned about the temps of the cpu ...

I see you have bios F10 when there are newer ones,update to F13 and see if that helps. Don't know which revision you have and it seems not to matter,but look at the lefthand bottom corner of the motherboard for that and choose the one you have,can be done in the next link next to the motherboard name/type,

unpack the download and put it on an empty usb stick,put it in,restart,go into the bios and find the update tool,it should find the file,let it update.

Hey Vic, which download to I pick exactly? There seems to be a lot of Drivers / BIOS / Utility downloads. I appreciate your help.

 

[Vic 40]

Pick your windows version,click on the "BIOS(+6)" and choose F13=>your region.Don't know since a "beta bios" if the newest one "U1D(UEFI BIOS)" is recommendable so why i choose F13 for now.

 

[loganc123]

Okay I have updated, i'll try to stress test and see if that helped any with my issue.

That's fast ...
