The 4-year-old's PC isn't showing video after being fixed.
My friend decided to sell his PC by taking it apart and cleaning it. Everything proceeded smoothly until reassembly. After putting it back together, the machine stopped working but remained powered on without any warning signs of failure. It was functioning normally before this issue. The system had an AMD A8-7650k with 16GB DDR3, a 2TB HDD, and a low-end FM2+ motherboard from Gigabyte—no model number visible. He tried changing the CPU and power cables, swapping memory modules, but nothing resolved the problem. Note: He uses a 550W PSU, though I don’t remember the brand, and it hasn’t caused issues previously. Edit 2: The fans on the PSU increased significantly when he powered the PC back on.
It might not be a good power supply; try identifying the brand. The Mobo unit could have failed. This PC is quite old, and the parts look poorly made. Do you have two power supplies? Use one to test if it works. Check the CMOS, then switch to another PSU.
You can reset the CMOS by removing the power and resetting the system. If you're unsure, checking the RAM and PSU connections might help. Let me know what you find!
Disconnect the device and take out the small battery from the main board for a short time, then put it back in.
Disappointing when this occurs. Many PCs I've worked on have experienced this issue, and sometimes others do the same. Removing the battery while unplugged is often a first attempt. At times, you might need to take it apart more thoroughly, working more slowly and carefully, because rushing or pressing too hard on ports or board components can lead to problems. In rare instances, a weak CMOS battery can also cause issues. I once left an LED powered for ten seconds and it failed when tested. Replacing the battery sometimes resolved the problem.
It doesn't mention a Cmos battery in the link. The information seems to point to other issues with the MOBOs. Your comment about someone reacting to things being funny isn't clear—could you clarify what you mean?
Also ensure his PCIe power cables are arranged properly in the correct PSU connectors (if modular). It’s a bit embarrassing, but often I forget to plug the aux power cables into the GPU after backing up the computer. If that doesn’t work, it might just be the motherboard defaulting to built-in video instead of the add-in GPU. Check for another video out port on the back and test it to see if the default video appears there. --Patrick
