Dell Dimension 5150/E510
For the last few days my above desktop has been creating a loud hissing noise when I turned it on. Think the fan is making the noise. Have cleaned the vents by airblowing but the noise is still as loud as ever. Read that it could be the BIOS being out of date? But I don't know how to renew it. I tried to follow the instructions in Dell help website but I got nowhere. Do you think the BIOS is the culprit or there is something else, like my computer is old and nothing can be done?
