New CPU, Won't Boot

Hi,

I recently got a new CPU and swapped it out with my old one but haven't been able to get the computer to boot at all. No beeps from the motherboard, no life signs whatsoever. Though if I put my old CPU in, it works fine.

Motherboard: Gigabyte GA-MA790FXT-UD5P
RAM: G.SKILL F3-12800CL9D-8GBRL (8GB)
New CPU: AMD Phenom II X6 1100T
Old CPU: AMD Phenom II X4 810

I've googled the problem but haven't found anything to help. My motherboard's CPU support list even shows this CPU as supported (here).

I've done other diagnostics like a memory test but both my modules passed with no problems.

I'm pretty puzzled by this, any help is appreciated.

Thanks,

-M

check if it needs a bios update to support the new cpu

check all the cables are securely connected

the Phenom II X6 1100T is supported IF you have the F8M BIOS version installed.

reinstall the Phenom II X4 810 and download the F8M bios update then follow instructions how to install (re: mobo manual for how-to on floppy/usb bios updates).

the bios update needs to be done before installing the new CPU as this update tells the system what the CPU is and what power/frequency settings to use at startup.

Success!... in that area. I got it to boot, into windows even, but I haven't had any luck in reinstalling windows. I can go through the install process all the way until it should start prompting me for user account names and the like, but when it (seemingly) gets to that point, the video cuts out and my monitor reports that there is no signal. At the moment I'm reinstalling windows for the third time (lets hope I get lucky), but it's not looking great.

Thank you all for your help, I really appreciate it.

Your Bios went to "Default" settings after the Bios flash. Boot to the Bios and change SATA to IDE-Compatible or something similar.

I checked my BIOS, everything seems normal, but the problem persists. I did figure out where my video went. For whatever reason, after flashing my BIOS, when I am installing windows, my video card switches over to VGA instead of the DVI cable plugged in (despite not even having VGA on my video card), requiring me to use a DVI-VGA converter to get video to my monitor.
Even after windows is installed I still could not get video over DVI until I installed my video drivers. I've never had this issue before, which is what confuses me. I've always been able to use DVI no problems, in and out of an OS.

If possible I'd like to fix this for future windows installations, as digging through my cable box for the right cables and adapters is a pain.
