The Short Answer

There are many reason why an IT professional would choose to re-install over repairing. A lot of spyware, trojans, malware, etc can destroy common system files as well as make the PC run slow. It's a lot less work to simply re-install windows than it is to attempt to locate and repair every single file that could possibly be damaged by the harmful software. It will also eliminate the possibility that another piece of software could be causing issues as well. Re-installing windows is essentially setting the PC back to how it was when it was brand new. Imagine if it'd be easier to replace your cars engine then repair a couple hoses. You'd probably rather just have the engine replaced every time so you know it'd be new and non problematic.
