[iErnest]

I boot my pc u normally and about 5 minutes later it freezes and mouse with keyboard dont respond anymore. I recently changed the thermal paste on my cpu and gpu and I also change my psu. If someone knows the problem and how to fix it please help.

Update your post to include full system hardware specs and OS.

Include PSU: make, model, wattage, age, condition.

Look in Reliability History and Event Viewer for error codes and warnings that precede or correspond with the times of the freezes.
