When I turn on my tower (Acer Aspire M1641-U1521A) everything lites up, fans run, DVD drive operates, but no video just a black screen. I took it to the shop and the tech said it was either the motherboard or CPU. I've tested the monitor many times with my other tower. Brought the unit home and replaced, mobo, CPU, RAM, fan, harddrive with brand new parts. STILL A BLACK SCREEN !!! MY question ? Is there anyway the power supply is at fault. I'm at wits end with this desktop. Thanks for any help.
