PC doesn't boot

I have a T2895. It doesn't boot up. I replaced the power supply because it doesn't work,but still nothing works. I read a similar problem from another T2895 and the solution was to buy a new motherboard and power supply. My question is: Could the problem be the BIOS ?

In the event of the BIOS being faulty you would in any case have to replace the mainboard, usualy if the motherboard was working you would at least get your pc to boot and give you some kind of beep as it runs through the POST checking all your hardware components, so i would suggest as the others have to make sure your cpu, ram and powercables are seated properly, if you are able to test your cpu and ram on another board it would be a quick way to asses if they are working, but in this case i would suggest getting a new motherboard as it sounds typicaly like a dead motherboard.
With this description it could be anything (well, except the PSU, as you have changed that already). Remove everything removable from the Mainboard, except the CPU, and try turning it on (make sure all the power connectors from the PSU are connected to the sockets on the mainboard).  Then if something happens, add one RAM module and try again, and so on...
Try also another video card.

If reseating the components does not work, It could be your motherboard or CPU that is the culprit.
clear the cmos using the jumper on the mobo, try resetting the bios back to factory defaults, make sure you have thermal paste between your processor & its heatsink + fan

test your ram:
test your hard drive
        chkdsk /r
we've been waiting for a response, if no split then del with no refund
