My desktop computer keeps freezing randomly every day. Sometimes it freezes for a few seconds, sometimes I have to restart. No blue screen.
Random freezes without blue screens are usually caused by overheating, bad RAM, or a failing storage drive. Start with temperature: download HWMonitor (free) and check your CPU temperature under load. If it exceeds 85 to 90 degrees Celsius, your computer is thermal throttling. Open the case and clean dust from all fans and heatsinks with compressed air. For laptops, make sure the vents are not blocked by soft surfaces. Next, test your RAM: search for Windows Memory Diagnostic in the Start menu and run it. It will restart your computer and test the memory. Any errors found mean you need to replace a RAM stick. For storage, check your hard drive or SSD health: download CrystalDiskInfo (free). If it shows Caution or Bad status, your drive is failing and you should back up your data immediately before replacing it. Also check your Event Viewer (search for it in Start) and look under Windows Logs, System for any Critical or Error entries around the time of your last freeze. This often identifies the specific driver or hardware component causing the freeze.
