Advice -MoBo or PSU broken

[GreGorGy]

MoBo=MSI MS-7529 (LGA775)

Machine was working just fine until this morning. I spent a glorious 2.5 hours getting from Fourways to Midrand and was called about 2 hours into that journey by the user. I told them to unplug the power and wait for me.

I get there and the following is apparent:
(1) The VGA D-Sub was loose at the back and had come off, probably when they pulled the power, so I don't believe it has anything to do with the problem. Reattached it and the issues persist
(2) When powered, the PSU and CPU fans spin. The (SATA) DVD drive opens and closes.
(3) Opti mouse has its warm red glow (USB connected)
(4) Keyboard is dead - PS/2 connected
(5) No POST

I tried switching out CPU and connected only the mobo (not drives) and still no post so I don't think it is PSU. Any ideas what else it could be before I toss the MoBo?

I usually first re-seat my ram modules. If that fails, I reset the BIOS.

No Post showing andfans on full blast is related to ram not registering.

This would be my first step as well

Thanks. Just done all the above and still no POST -I may try swap out the RAM if I can find a replacement.

Ok plug your components in one by one. Remove your graphics cards.

Plug only the Ram and the CPU in at first then check if it posts. Remove everything else.

Graphics card is built in. I will go through this process tomorrow morning with the machine - I have RAM at home I can switch to eliminate.

Went through the process - still no POST - assuming MoBo is Loco.

Oh, and thank you everyone for your assistance
