I was going to buy a pc on eBay and upgrade it and found an i3 pc on an auction with no bids with 6 days left. After bidding I found out it was broke which was my fault I didn't pay much attention.im just trying to figure out if it's an easy fix or if I should file a bid cancel form.the seller says after 5 minutes of running fine the pc shows "bios error" and won't run,and that mechanics said it was perfectly fine.is this a cheap and easy fix or not worth my time?
