Hi all, Iam using Windows 10

 

I was playing a game on my PC when suddenly it crashed completely. Just Fzzz!!! and went dead/

 

I thought faulty RAM

 

After removing my video card, battery it still would not boot up.

 

I read somewhere to try taking the cables out of the HDD for a minute then put them back in and try.

 

That worked in as far I got a looping message in that dreaded Windows repair.

 

Screen came up offering me a choice but my mouse and keyboard No light not working.

 

Then suddenly it boots up with one stick of 4....then I try 2 sticks it boots up again 3 it boots up again 4 nothing although once when I put Ram no 4 in it gave out a long continuous beep so I quickly turned it off

 

Every other time I put in the last stick I got nothing...no beep no start

 

Problem solved I thought .........so I go out and buy a new Ram Stick

 

Shut down the PC put the Ram in the 4th slot and it's still dead as a dodo ;0(

 

So I take all the RAM sticks out and put the new ram in the offending chanel

 

PC boots up without a problem

 

I go through the whole thing again adding one stick at a time no problem until get to 4 and still wont start.

 

Obviously my Ram match ok as my PC was running ok.

 

Can anyone shed any light on what is suddenly causing this problem

 

Thanks in advance

In 41 years of fixing these things and about 150,000 busted PC's, I have seen this about twice so it is mighty rare; but, either the system board has gone bad or one of the cards in a slot has gone bad and is conflicting with using the memory in slot 4. Both times I have seen this, it was the system board.
There is some slight chance that it is the CPU (the memory controllers are now in them); but, most especially if its an Intel CPU, my bet would be on the board itself.

Thanks Davis...With odds like those I should have done the lottery :0)

 

I just tried taking all the ram out and working from 4 back to 1 adding one at atime and staring my PC each time...All went well until I put the last card into slot 1.

 

I did get a single beep and thought solved but Nope...tried again no beep.

 

Back to 3 sticks..leaving slot 1 empty this time.....no problem.

Geo,
You had said in your first posting that it was slot 4 giving you the problem; but, now you say it is slot 1. You may well discover that it doesn't matter which slot is empty as long as one of them is if this is indeed what you are seeing.
The memory controller, which is part of the CPU chip, will automatically reassign which slot is used for which address space depending on the size of each module.
Is it an Intel CPU or an AMD?
Do you have any cards in PCI(E) slots? (especially PCI slots)
What is the make and model number of the system board?
What size are the memory modules?

Remove all but one RAM module that is know to work.  Try this in each DIMM slot, install the modules and start the computer, do this with the one module in each DIMM slot.  If the module works in all of the slots but one there is the possibility that there is a problem with the slot or there is something in the slot keeping the module from making proper contact.  Check the DIMM slot for any signs of arcing.  I would check the pins to be sure there is no corrosion.  A pencil eraser does a good job of cleaning these pins.

It seems like it can't cope with 4 x 2 GB since it crashed no matter which ones I use or which slots I use

That motherboard will support up to 16GB of RAM.

 

Are all of the modules the exact same modules.  Make, model, capacity, part number...

As I already said, either an add-on card is conflicting with the memory space, the CPU has failed (its where the memory controller is), or the system board is bad.
If you have any add-on cards, take them out and try it. (You'll have to leave the video card in; but, take out the others)
You can try reseating the CPU chip if you have some thermal compound and are comfortable doing that.
But; my bet is that the system board has gone bad:

The Ram worked together for years before my pC crashed

I did have a creative sound card but it didn't work properly with windows 10 so I removed it a couple of months ago ....will try reseating ..thanks

Hi, probably the MB, the memory controller is in the chipset (Intel LGA775 based processors ) . Worth a try to download the latest chipset drivers, though I agree with Davis, looks like a hardware issue.
