[SOLVED] Problems with changing CPU

[abhishek72457]

Hi,

I have a Mercury PI945GCM motherboard. Its old but still working. I tried putting Newer Cpu as i am running too old. So i tried putting Intel Core 2 Quad q8400 in exchange of Pentium Dual Core E2160.

After installing New CPU. I cant see anything on Monitor. No connection at all.. tried removing cmos battery and put it back.. After that i reinstalled old CPU. But now my keyboard and mouse don't connect. What should i do? Do you have any updated BIOS?
And I am left with No system at all.


Edit: Dumped them

It sounds like one or more of several possible things have happened:

#1: The motherboard has become so old and fragile that putting a Q8400 in it caused some kind of damage in the power delivery circuits.
#2: You weren't wearing static protection and accidentally shocked a circuit on your motherboard.

Either way, it sounds like your motherboard is dead. Remember that you're working with parts that are over a decade old and when they get that old, they get brittle and fragile. Doing things as simple as changing the CPU on old boards like that can kill them (It happened to me on an ASRock 4Core Dual-VSTA motherboard when it was about that old).

Your description definitely fits a partial motherboard physical failure and I don't know of any way to repair motherboards damaged in this way. An update BIOS cannot solve this problem because updated BIOSes don't repair physical damage and even if they could, how will you flash the BIOS without a keyboard or mouse for input? You can't.

I'm afraid that until you get another motherboard to replace that one, you have no system. Fortunately, old LGA 775 motherboards aren't exactly expensive because Intel used the 775 socket for a VERY long time. I'm afraid that because I don't know where in the world you are, I don't know where to tell you to look except maybe eBay or your local classified ads.

Dumped them

Dont dump the CPUs or the RAM! They're probably still good. It's the motherboard that's the problem.

Yes It was working quite good till today.. i upgraded Ram a couple of years back. CPU is way too old. And it became too slow.. So i am going to sell parts on olx/ebay/quickr.

Btw it was a spare pc which i thought kids will learn on. But i totally messed it up.

Thanks so much
