Common Causes of Dell G15 Running Slow

Too many background applications – Extra apps consume CPU and RAM.
Overheating – High temperatures lead to thermal throttling.
Outdated drivers – GPU, CPU, and BIOS updates are essential.
Storage issues – A nearly full SSD/HDD slows down performance.
Malware or viruses – Unwanted programs can slow down your laptop.
Fragmented or corrupted files – System files affect speed.
Aging hardware – A failing SSD, RAM, or GPU can impact performance.
