This Dell Studio desktop would no longer power on after storms in the area caused a power outage. This is a common issue with older power supplies. If they are old and damaged from years of excess heat and clogged fans they can fail when power is lost unexpectedly or there is a power surge.
We replaced the power supply with brand new and more robust model. The new power supply has a larger fan and better components to ensure it will last a long time and keep the computer up and running with no issues.
