Hello my friends as I do not have any experience with trouble shooting these all in one PCs what would you recommend... PC was working great then one day poof will not even post or open bios. Guessed it must be PSU blown, as fans spin up, stutter and then no bios. after swapping PSU problem still exists. Please note I have no donor boards to try. -Tried with only one stick of ram still no bios, -Even tried with nothing connected to motherboard except CPU and one stick of ram. Still no bios. Tried ram from other PC that works. Before I give up what ells can I try? If all fails what would be the cheapest office/photoshop set up I could build at this time for just MB, RAM and CPU with integrated graphics. I am guessing some type of AMD build. Extremely tight budget. Also time is an issue due to it being needed for tax record keeping.
