Had many dramas with my computer and took my tower in for a check over. I was told $50 for a clean and for some scans to be done. Two days later I picked it up with no hardware issues. They had told me it was software conflict and deleted them for me. I had a good chat with the saleman there and he explained everything clearly and in detail. He didn't hide anything and was very helpful. Since having my computer back, it is super fast and although I have got an issue with it again...was told to bring it back if anything happened again. Best $50 ever spent...
Approximate cost: $50
