My desktop PC is an HP Pavillion with a Bestec ATX 250 12Z PSU. Went to switch on this morning and zilch, nada, only a blinking green light on the rear of the PSU. I have opened the beast up and given it a good degrot, checked all connections and no joy. I have emailed HP support but as it is well out of warranty do not expect a swift answer. Has anyone had a similar problem with this model?. I am going to be away for a few days from Sunday, so any repairs will have to wait, in the meantime I look to my fellow ARRSErs for any guidance.
