Is my Mother Board Dead?

[BuckMaster]

I currently was running a MSI K7t266 Pro2 MB with a XP1600 with a Enlight 300W PS ran great! I just upgraded my main rig so was switching my previous XP2100 to the MSI K7t266 Pro2 board. I also traded a NEW Antec 350 Watt PS I installed also from a member here on Anandtech for a H/D. Which Im sure is good looks brand new so I dont think thats the issue. Read on....

After installing both CPU and PS the monitor kicks off and cant even get as far as the BIOS screen! I then tried the following to see if I could find the problem: Tried switching back to my previous 300W enlight PS, tried reseting 2 sticks of memory then tried 1 only, changing and removing ALL IDE cables and tried new ones, clearing the CMOS, another H/D and video card! Still no luck!

The only thing that seems left to me is the board or CPU? I double checked the CPU and is on and secured! Also its seems the H/D light stays lite at all times! Im thinking it might be the primary IDE controller is bad? It just puzzles me it worked fine till I broke it down. I can always limit the CPU by switching out the XP2100 to the orginal Xp1600 too. Your thoughts and thanks!?

If you think the board is bad your thoughts on a new O/Cing cheap board!

If it ain't broke.........................! God I hate that saying. Ok, first things first. Try unhooking all "extra" items like fans, extra drives etc. Just have MB, ONE HDD, ONE stick of RAM, CU w/HSF and floppy and videdo card. Nothing else. Clear CMOS to start by leaving the MB battery out for about 5 minutes (overkill, I know). Then put jumper in Clear position during this time frame. Then try to boot to the BIOS. If no luck, try again without a HDD (clearing CMOS and removing battery again) and just a boot disk in the floppy drive. Again, no fans other than the onen on the HS. Use the original cpu also. If you can get it to boot, then start by adding one item at a time back to the system. Concentrate on fixing the "old" setup first, then retry the upgrade. This time, do the PS first; then the CPU upgrade.

welp I think I found the culprit!

Im assuming my XP1600 is a Palomino CPU? Because I put it back in and works great!
After reading on MSI's website it says it supports AthlonXP ((Palomino 0.18u) XP1500 to XP2100. But DOESNT support any of the Thoroughbred (0.13u) XP1700 up to 2100 which is what I was trying to use! Pretty lame!
