My name is Jeannot thewissen.
I got a dell Optiplex from a friend, because he said it wont power on.
So I tested it powers but if you power it on you dont get any video or sound. The only thing that happens is that the fan in a few seconds maxed out on rpm.
I did search google and i found it can be a broken psu or a bad cmos battery. Both replaced. when I replaced the PSU the computer worked for a day. I wanted to install windows today and the same problem again, CPU fan maxed out in few seconds.
So is it a broken motherboard or is it bad PSU?
Any help would be appreciated.
