compatibility problem cpu mobo compatibility problem

[david97]

My sisters pc just stopped working, and when i looked into it i recognized, that there was a condensator, which was twisted. This is an old system, bud they got it not that long time ago, so we had the previous pc. So i switched the motherboards, and when i fired up the system, it turned out, that the bios was too old, that it can't recognize the cpu(motherboard: gigabyte ga/945gcm-s2c, processor: intel core 2 q9300). Ok, no problem, than update the bios. (the following stuff isn't important, just the painful story of the bios update.-->> so i changed back the cpu, to the previous, to the working motherboard so they can at least use them pc. The bios update is only possible through floppy, so i had to get a floppy driver, than a floppy drive. when i had everything, i had to install another os, which is capable of  reading floppy. so i just quickly downloaded a windows xp, which said it culdn't be installed, because "The installer didn't found the users licence code. The installion is impossible, to exit press F3". ok, than install some old ubuntu, than download the bios file and we are cool. But the installer of the ubuntu didn't showed up in the bios, so i grabbed the winchester, put it into my system, installed ubuntu to it, went back, and prayed for all of the gods to make it work. And it did worked, but i found no way, to connect to the internet, to download the files. So i went back to my pc, downloaded the files, put them onto a pendrive. On the linux system copied them onto the floppy and hit the restart)<<-- I could update the bios with no problem. Everything worked, the bios had been updated. When i changed back the cpus, and fired up the system, there was the following image. It doesn't see anything, only the processor, but nothing else. Not even a keyboard, to get into bios. Now i have no idea what the hack should i do. Checked the bios's "manual", it is compatible with the cpu. Checked the motherboards manual, it is compatible with the cpu. 

So if you have any idea how to fix this issue, i would very appreciate it.

not my area of expertise but after the cpu it checks ram so maybe try taking all ram out and just using one stick at a time in each slot to see if you have a bad stick or bad slot?

Did you try going into the BIOS, then pressing (probably) F10 and booting Again? could be that you mobo just wants you to go into the BIOS once, alsi there you could select the bootdrive, maybe it doesn't boot the OS or changed sth up.

with the cpu, (which worked before the bios update) yes i did, set the bootdrive but with the other one it just sits at this screen and do nothing

@SamuraiXV1 good idea, i will try it

also worth mentioning that if the lga is not seated correctly or a pin is bent that may allow it to boot but there may be certain things not working like for example pci channels or memory controllers. so if nothing changes after checking ram maybe look at reseating the cpu or checking the pins on the socket.

 

did you try booting with the old cpu after the bios update at all? if so and everything worked it will be unlikely you've got bent pins.

But it works just fine with the other cpu, so the pins must be alright. 

And thank you for helping
