PC Hardware Diagnosis & Repair

My Windows desktop boots, reaches the desktop, then freezes or reboots without warning—no blue screen, no error code, sometimes while it’s just sitting idle. I need the underlying hardware or system fault identified and resolved so the machine can run for hours without crashing.

You will have full access to the tower. Start by stress-testing and monitoring every critical component: RAM (MemTest86), SSD or HDD health (CrystalDiskInfo or similar), GPU stability (FurMark, Heaven), and overall system thermals. Check power delivery from the PSU and rule out motherboard issues. If Windows itself is corrupted, repair the installation, restore boot files, or reinstall while preserving data.

Once the culprit is isolated, replace or reseat the part, update firmware or drivers, and confirm stability with repeat testing. If a component proves irreparable, suggest a compatible replacement model and explain why it solves the problem.

Deliverables
- Written diagnostic report detailing each test performed and its result
- List of actions taken to fix the fault, with before-and-after stability evidence (screen captures or logs)
- Recommended replacement parts, if any, with links or model numbers

I value clear communication and decisive problem-solving; please be comfortable working hands-on with Windows 10/11 PCs and common hardware troubleshooting tools.
