It's about my daughter's computer. Every time I remove (and re-connect obviously) the power cable connecting PSU to wall socket, the computer refuses to POST. No beeps. To get it to POST again I'd have to remove and re-insert the graphics card. If this happened only once I'd have thought it was a coincidence. But it happened three times already. Otherwise the pc works perfectly. Always turns on, never freezes, never bsods... What on earth does the power cable have to do with the vga?
