PC won't boot after adding a Ram.

[ExtremelyPoorGamer]

I bought a 3rd ram and a hdd. I had ram in dual channel before. I have wasted 4 hoirs and searched all over internet and this forum is my last resort. Everything runs okay in each try but no signal to monitor.

 

I have explained the whole thing below. between each "try" ,I reset the cmos by removing battery.

 

Try 1: Added the 3rd ram. PC boot successfully and showed all ram size. However after installation of hdd PC won't boot.

 

Try 2: removed gpu . And from now on in every "try" no gpu only igpu. No boot

 

Try 3: changed ram slot of 3rd Ram. No boot

 

Try 4: Removed 3rd Ram. Boot successful. Can see the new hdd too 

 

Try 5. Removed dual channel old ram ,added 3rd ram only.No boot. 

 

Try 6 changed 3rd ram slot while kept the old 2 rams away. No boot. After changing slot again Boot sucessful.

 

Try 7 Added old two ram along with 3rd ram.No boot.

 

Try 8 removed 3rd ram and added old 2 ram. This was the same configuration before adding 3rd ram. No boot

 

P.S i have checked monitor and gpu cables.

First, you should make sure that removing the battery is enough to clear the cmos of your computer. You usually need to short two pins in addition to removing the battery. But it differs from manufacturer to manufacturer. Check your user manual to make sure of the correct procedure.

As for adding a 3rd ram stick, this is generally a bad idea. Ram is usually bought in sets of two sticks. Not counting if the ram you bought has different timings/frequency, you can end up with a ram problem.

From your experiments, it seems that using the original two ram sticks and adding the new hdd was a working configuration. I think that is the best to hope for at the moment. As for the extra ram stick, you can try to return for a refund or exchange for two sticks identical to the ones you already have.

what i don't understand is why in try 1 it worked perfectly fine while in try 8 even the old two ram didn't worked.

And now even original configuration ain't working

What's the brand and model of the CPU, motherboard and RAM?

Read my recent reply for another added info

 

CPU - i5 6500

Motherboard - asus b150m gaming

Ram old 2*4gb hyperx 

Ram added Sk hynix 8gb 

both ram are 2666mhz but timing is a bit off. I successfully installed the 3rd ram in my first attemp and even windows and cpuz showed it.

 

Right now no boot even when i use the 2*4gb ram which worked fine so far

May be a difference in how you inserted the sticks (a bit of dust, partial contact, etc.) or your cmos wasn't cleared when removing the battery and the BIOS kind of 'learnt' the RAM configuration the wrong way. Mixing different ram sticks is a finicky business.

Also, the order in which you put hardware in sometimes matter. Best advice I can give you is try your components in another known good computer to rule out defects.
