Initially, I suspected the issue might be related to the RAM configuration. The system was equipped with 16GB of RAM, but the two sticks had mismatched speeds. Since the PC doesn't support dual-channel memory, it defaulted to the slower speed (8GB RAM stick). This resulted in suboptimal performance.Additionally, the PC struggled to run Windows 11 due to its specifications. It repeatedly attempted to perform Windows updates but failed to complete them. After a month, the PC completely stopped working.A word of caution: Be very careful before purchasing a PC from this vendor. Ensure you thoroughly check the specifications and compatibility. Also, pay close attention to the 2-week warranty, as it feels like a deceptive tactic.
