I bought a brand-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 cannot move the mouse or use the keyboard. Turning the monitor off, unplugging the monitor cable, or reconnecting power to the monitor does not help. The only way to recover is to hold the PC's power button or otherwise shut down the entire computer, after which the problem eventually happens again.
The freezes seem especially likely when I try connecting something through Bluetooth. The PC does not power off by itself; it remains frozen until I manually shut it down. Windows 11 was preinstalled, and I have not installed anything else.
The system has an AMD Ryzen 5 7500X3D processor, an ASUS B840M Max Gaming AX motherboard, 16GB of DDR5 memory, a 1TB SSD, and a PRO MP273L E13 monitor. Could this be overheating, a missing or improperly installed component, faulty memory or storage, or another assembly problem?

A temperature problem is possible, especially if the cooler was installed incorrectly, the protective film was left on, or the heatsink is not making proper contact. If you do check temperatures, use a hardware-monitoring tool while Windows is running, or enter the firmware setup and watch the CPU temperature there. However, opening the case or removing parts could affect your return or warranty, so it is safer to ask the seller first.
Because the computer is only two weeks old, the first recommendation is to contact the store or manufacturer and request a repair or replacement. A complete hard freeze can be caused by overheating, defective RAM, a faulty SSD, an unstable Windows installation, a bad motherboard or processor, or a power problem. You should not have to dismantle a new system just to diagnose a defect.
The Bluetooth connection triggering the freeze could indicate a driver, motherboard, or wireless-adapter problem, but it may also just be exposing an existing hardware fault. Avoid repeatedly swapping internal components or changing BIOS and disk settings before speaking with the seller. Record when the freezes happen, take photos of any error messages, and have the shop handle the diagnosis under the warranty.
Look in Windows Event Viewer under the System logs and check the entries around the time of the last freeze. Critical errors or warnings may point toward a driver, storage, power, or hardware issue. These logs may not identify the exact failed part, though, and a hard lock often leaves little useful information behind.
The PC never shuts down on its own; it only becomes completely frozen and has to be powered off manually. Since the store is several hours away, I may need to call them and ask whether they want me to bring it in or use a nearby service center.
