I bought a new prebuilt PC about two weeks ago, and it randomly becomes completely unresponsive. Sometimes it runs for nearly an hour, but other times it freezes after only a few minutes. The display stays stuck on one frame, and I can't move the mouse or use the keyboard. Turning the monitor off, unplugging its cables, or reconnecting the display doesn't help; I have to hold the PC's power button or otherwise shut the entire computer down. After restarting, the problem eventually happens again.
It also seems to freeze specifically when I try connecting a Bluetooth device. The PC has Windows 11 preinstalled and no other software that I know of.
Specifications:
- AMD Ryzen 5 7500X3D processor
- ASUS B840M Max Gaming AX motherboard
- 1TB SSD
- 16GB DDR5 RAM
- MSI PRO MP273L E13 monitor
Could this be overheating or a hardware assembly problem? Since it's brand new, should I return it instead of trying to repair it myself?

Because the computer is only two weeks old, the first recommendation is to contact the seller and request a repair, replacement, or refund. A complete hard freeze can be caused by overheating, faulty RAM, the SSD, processor, motherboard, power supply, drivers, or a damaged Windows installation. There isn’t enough information to identify one part confidently, and you shouldn’t have to diagnose a brand-new system yourself.
You generally don’t need to replace parts or perform extensive troubleshooting before contacting the seller. Opening the case or changing components could also complicate a warranty claim.
If you want a basic temperature check without booting fully into Windows, enter the motherboard’s UEFI/BIOS setup during startup and view the hardware-monitoring page. Do not change settings or disconnect components unless the seller tells you to. A normal idle temperature there would make severe CPU overheating less likely, but it would not rule out RAM, motherboard, Bluetooth, driver, or power problems.
Since the system is under warranty, I’d avoid unplugging the drive or opening the case just to test it. The seller should handle any internal inspection.
Overheating is one possibility, especially if the cooler was installed incorrectly, the protective film was left on, or thermal paste was missing. You could monitor CPU temperatures with a hardware-monitoring utility, but since this is a new prebuilt, it may be safer to let the seller inspect it. Avoid repeatedly stressing the machine while it is unstable.
Check Windows Event Viewer for entries around the time of the last freeze. It may show hardware errors, driver failures, or unexpected shutdowns, although a hard lockup can sometimes leave very little useful information. If the computer stays running long enough, look under Windows Logs and then System for recent critical or error events.
I’ll try checking the System log if it remains stable long enough to capture the entries. I’ve already seen warnings and errors, but I’m not sure which ones are relevant.
It never powers itself off; it stays frozen until I shut it down manually. The store is several hours away, so I’ll contact them first and ask whether they want me to bring it back or use a local service center.
