Stuttering issues on new Hp Omen 40l

[DigitalX]

I bought a brand new Hp Omen 40l at the beginning of February (2025). It took some time to get used to my new pc. I realized that it stutters randomly on every game. I was just outside of my return window and I've had to deal with hp support, which turned out not being helpful. I've researched for weeks on how to fix this issue and I can't figure it out. Not only will the pc stutter but it will disconnect my Astro A50x and Xbox controller sometimes when it happens. I've updated bios, chipset drivers, upgraded and reinstalled windows, upgraded my ram from 32G to 64G, tried disabling fTPM in bios, had HP take over my pc virtually and go through several things on my pc, updated everything that's listed on the HP website, uninstalled AMD Adrenaline then reinstalled just the drivers, made sure to update windows, updated Nvidia GPU, and a few other things that I can't think of off the top of my head. I used Ryzen Master and watched my cores. All 8 cores randomly spike for no reason whatsoever just sitting idle. I'm pretty sure that's what's causing the issue but I have no idea how to fix it. I also have a brand new router and cable modem with 1Gb internet. Any help would be great. This has been extremely frustrating. Oh and it only seems to happen when I'm gaming no matter what game. I checked Task Manager and there's only 81 processes running.

System info:

Hp Omen 40l Desktop GT21-1xxx

AMD Ryzen 7 7700 8-Core Processor 3.80 GHz

64 Gb Beast DDR5 RGB XMP DDR5 (5200 MT/s)

@DigitalX, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

That sounds incredibly frustrating, especially after all the troubleshooting you've done. Given that the issue is specific to gaming, affects USB devices, and causes core spikes, here are some possible causes and solutions:

1. USB Power Interruptions (Affects Astro A50X & Xbox Controller)

Since your peripherals disconnect during stutters, it might be a USB power delivery issue.

Try this:

Disable USB Selective Suspend

Go to Control Panel > Power Options > Change Plan Settings > Change Advanced Power Settings.

Expand USB settings > USB selective suspend setting > Set to Disabled.

Check Power Management for USB Hubs

Open Device Manager > Universal Serial Bus Controllers.

Right-click each USB Root Hub > Properties > Power Management.

Uncheck "Allow the computer to turn off this device to save power."

Try Different USB Ports

Use different USB ports (preferably USB 3.2 Gen 2 or USB-C on the motherboard).

Test with a Powered USB Hub

If possible, use a powered USB hub to rule out power delivery issues.

2. CPU Spikes & Game Stuttering

Your Ryzen 7 7700 randomly spiking at idle suggests a power or background process issue.

A. Check Background Processes

In Task Manager > Performance > CPU, click "Open Resource Monitor".

Look at the CPU Usage by Processes.

If any process is consuming CPU constantly, try disabling it.

If HP Omen Gaming Hub is installed, try uninstalling it (it sometimes causes performance issues).

B. Change Power Plan to Ultimate Performance

Open Command Prompt (Admin) and run:

• powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

Then go to Control Panel > Power Options and select Ultimate Performance.

C. Disable fTPM (If Not Already)

Go to BIOS > Advanced > fTPM > Set to Disabled.

D. Limit CPU Boost Behavior

Ryzen's PBO (Precision Boost Overdrive) can cause erratic behavior.

Try setting a max clock speed to stabilize it:

Open Ryzen Master.

Click on Advanced View.

Under PPT, TDC, EDC, set:

PPT: 120W

TDC: 90A

EDC: 130A

Click Apply & Test.

E. Check RAM XMP Profile

Omen BIOS sometimes struggles with XMP memory profiles.

Go to BIOS > Advanced > Memory Settings:

Try manually setting RAM to 4800 MT/s (instead of XMP at 5200 MT/s).

Save and reboot.

3. GPU-related Stuttering (RTX 4070 Super)

Your RTX 4070 Super might be power-throttling under load.

A. Check for Power Limitations

Open NVIDIA Control Panel > Manage 3D Settings:

Set Power Management Mode to Prefer Maximum Performance.

Set Low Latency Mode to Ultra.

B. Try Disabling Hardware-Accelerated GPU Scheduling

Open Settings > System > Display > Graphics Settings.

Toggle Hardware-accelerated GPU scheduling OFF.

Restart.

4. Latency & System Interrupts

Use LatencyMon to check for high DPC latency:

Download: https://www.resplendence.com/latencymon

Run while gaming.

If it shows high latency (above 1000 μs), it's likely a driver issue.

A. Try Disabling AMD Power Management Drivers

Open Device Manager > System Devices.

Right-click AMD PCI Express Root Complex > Update Driver > Let me pick > Microsoft PCI Express Root Complex.

Reboot.

Final Steps

Try Running in a Clean Boot State

Run msconfig > Selective Startup > Disable all non-Microsoft services.

Reboot and test.

Try an Older NVIDIA Driver

Sometimes new drivers cause stuttering.

Use DDU to remove current drivers, then install Driver Version 537.58 (October 2023) from NVIDIA.

Check PSU Wattage & Stability

Your PC should have at least 850W PSU (80+ Gold).

If possible, check voltage stability in HWMonitor.

I hope this helps. 

Take care and have a good day.

Sorry about the delay in response. I've been really busy. Everything you listed was something that I've tried or had already tried. None of these solutions fixed the lag issue.

@DigitalX, Welcome to HP Support Community,

Thank you so much for posting your query! My colleague @Max3Aj is currently out, but don't worry – I’ll be taking over and making sure we get this sorted for you.

HP Diagnostics Test: Run HP's built-in diagnostics to check for hardware issues.

Restart your PC and repeatedly press the ESC key until the Startup Menu appears.

Press F2 to enter the HP PC Hardware Diagnostics.

Run the system tests, including the extensive test, for a thorough check.

Check for Background Processes: Even with 81 processes, some background tasks can cause spikes. Use the Resource Monitor to identify any processes that intermittently use high CPU resources.

Inspect USB Devices: Since USB disconnections occur, consider testing with different USB devices or ports to rule out port-specific issues. Additionally, check for any firmware updates for your peripherals.

I truly hope these steps help get things back on track. If you have any questions or need any further clarification, just let me know – I’m happy to guide you through it and make sure everything works perfectly.

Take care, and I hope you have an amazing day ahead! 😊

Problem solved? 🎉 That’s fantastic! If you could mark this as the Accepted Solution, it would help others find their way here faster. And if you found this helpful, a simple ‘yes’ would mean a lot – it makes my day and gives this reply a little street cred! 🏅
