So helping a friend out do some minor upgrade to their pc, new fans installed and 1tb SSD installed awaiting to be cloned as they have an old school HDD only and recently been having issues with the system being a bit slow at times (Hence the upgrade to SSD) One of the fans already in he pc case seems to have well shorted out or something as the cables for it now in places no longer have the plastic coating on as it melted it. Have removed this fan from the system, checked all that is visible with no sign of damage to other components but the system still just wont put an image on the screen despite turning on (with no smoke) could this fan of damaged other parts without visible damage?
