Won't power on, possible motherboard issue?

Have a dell inspiron that at first wouldn't do anything when I'd try to power it on. Tried the routine easy things and then decided to try a new power adapter, still nothing.

So I let it sit for a while and then decided to open it up and check all my connections. After putting it back together the light now comes on when I plug it in and it tries to turn on when I press the power button, fan starts spinning and then it just stops, still nothing from the monitor. Did notice that the memory card gets really hot when I try to turn it on, is this an indication that my motherboard is toast? If not, any ideas what else it could be?

How about the cheapest thing?

In reply to: Won't power on, possible motherboard issue?

I don't see model number (more than the series please) so how about the old CMOS battery? Some PCs just stay in reset when it's too low. Is this worth a dollar to try or did you get out the Volt meter?

Sorry the model number is Inspiron 14 3451 . Also checked the cmos battery and it's putting out 3.0v

3.0V is the lowest I'll accept.

That to me tells me it's been around many years. It's the cheapest possible part it could be.

Is that the Dell I3451-1001blk ? That could be in warranty and under a year old.

Try that and unplug the RAM, HDD, ODD, WiFi and what else and see if it comes up, even to complain. I see used models for 249 so repairs usually cost more than a replacement today.

I believe that's it, it just comes up as Inspiron 3451 when I put the service tag in the dell site. Sadly the warranty just ran in August.

I'll try a new battery and unplugging everything the next chance I can, thanks for the help.
