Question I have an old Dell that I believe has a motherboard issue. I wanted to try and see if there are any compatible MBs 4C XEON E3-1270v2,3.5G,8M,0GT, Dell

I have an old Dell PC that I'm trying to get up and running. It was running for a while, I did notice each time I boot it up, it makes me set the date/time but later on it makes me do it again. I thought maybe bad CMOS battery but I would not think this would cause it to not work at all later on. It ran for a while but was making kind of a loud noise, I ran diagnostics on it and thought it might be the Sata drive it came with. I ended up replacing it with a new drive and installing windows. It worked for a while but then it would just randomly shut down. Now when I boot it up, I don't hear it post at all.
I am thinking maybe the CPU is still good but the motherboard is bad?

When I look on Dell site for my PC, this is the CPU I believe I have:

4C XEON E3-1270v2,3.5G,8M,0GT, Dell Precision T1650

Would it be a Xeon E3-1270v2?

Are there sites where I can plug in the CPU I have and it tells me which motherboards are compatible? I know this is old, but wouldn't mind making it a PC where you can browse the net and watch youtube and email.

Thanks in advance! I appreciate any advice or feedback. I am not an expert at all in building PCs, but I'm trying to learn more.

Welcome to the forums, newcomer!

A grounding issue can cause a CMOS battery to loose power to the board and can also lead to a faulty or failing PSU. You sure it's not the PSU? It might also be a corrupt BIOS, which can be circumvented by reflashing the BIOS with a CH341A BIOS programmer.

Hello, I bought an used Precision T1650 on eBay. The CPU is a xeon e3 1240 v2. When I received it, the first thing I have done is updating the BIOS, to ensure having latest security patches...

Thank you so much for all your help on this. Maybe I need to check the grounding. I did play around with it yesterday, I could get into the Dell Diagnostics and it was running through the tests successfully and almost done but it then shut off. Even though there is a power button in the front, there are times I have connected the power cord in the back and it turns automatically on. Maybe that is causing an issue. The BIOS could be corrupt, I did see your link where they had an issue flashing theirs, but with other assistance, got it back up and running.
Thanks for the link for a replacement board, I think I might need to check this grounding issue.
