(THIS IS A NEW THREAD! PLEASE DO NOT REPLY TO THE OLD THREAD THAT I ACCIDENTLY MARKED AS SOLVED.)
Hello, i have a dell studio xps from 2008 or 2009 (it also has a bigger case and it has INTEL cpu.)
This is the motherboard i want to now have:

It is the exact same as a Dell Studio XPS. To see if i actually i am talking about another dell pc, you can compare the specs in speccy and a dell studio xps.
Im pretty sure the new motherboard would fit as it has a lot of space.
Why i want to have this motherboard?:
1. UEFI (yeah... lol)
2. to try to fix the crashing or reboot and freeze problems.
My speccy specs:

sudden freeze and crash of pc and then restarting may be an indicator of a hardware problem. I had a similar issue with my old pc . try removing the ram and cleaning the gold pins and then re installing it. if that doesn't make any difference try removing 1 stick of ram and running your pc on the other. repeat the same with the other stick. hopefully you may be able to find out something. but why do you want to repair a 7 year old pc. trust me it is not worth it. better buy a new pc.

"of a hardware problem"
Yes, i believe that, but i have kubuntu and windows dualbooted and it seems kubuntu is more stable, but the problem continues. Sometimes windows is stable as kubuntu.
"ram"
Nope, RAM is fine.
"not worth it"
It is a very great PC for its time, and a good/great PC in this time. Even it has 64bit processor!
"better buy a new pc"
Gonna already get a Surface Pro for birthday. (No, not the 2 or 3.)
