If you can help me solve my problem I will be more than happy to compensate you for your time! (PayPal) Okay so to be precise, it is a Toshiba Satellite A305-S6857 The problem is that the computer will completely shut off at any given time. It will sometimes boot into windows but it will be a black screen with only the cursor until a blue screen pops up that I never have enough time to read through. It won't stay on trying to install a new OS or in the Setup Manager. What I've tried: Removing hardware one by one to see if it was the problem Completely cleaned heatsink Removed battery and ran only with power cord Power drain Replaced motherboard with a used but working one Let me know if you need anymore information. Thank you in advance for your time!
