PC don’t boot after ram upgrade

Asked by Tokouneli*0 on 2014-04-04

My problem is this.
Recently I bought a set of ram, the reason is for upgrade not because I had a problem , but because I want to do a dual boot.
After placing both ram in the computer motherboard it wont boot, and stuck in black screen showing the option that says to click if you want to get into the BIOS (ESC) or where to boot from (DEL). When this happened, the keyboard does not work .

So no available testing with both ram on the m/b.
The following applies for the set of ram tested both chips but individually (one at a time) on each slot of motherboard every time
The first enters and when I open the terminal and the command "sudo lshw" and code it crashes, the same happens if I try to open a browser.
The second gives me the result of "sudo lshw", but after a quick period it crashes too (by crashing I mean that GUI freeze).
In short , after a few seconds you will get stuck with both of them.

So far I tried and checked:
1) To run memtest from grub (with each chip separately) and after login to blue screen it restarts automatically – I suppose it fails.
2) To run from LiveCD 12.04 & 13.10. It shows that with 13.10 it can keep going a little longer and running smoother but eventually it will freeze.
3) I checked for faulty capacitors on the motherboard.

So far I really need to try these ram on another pc just to confirm they are not damaged –but I don’t have this option yet.
There is possibility that the motherboard need the last two updates after it’s version installed –but I don’t have the proper equipment for this (UPS) or the knowledge.

Have you tested the RAM using memtest86+ from Grub?

Yes, and it fails too.

Then this is an issue with the hardware, not Ubuntu

Thanks actionparsnip, that solved my question.

OK, thanks.
Either way i have first to check hardware.
Thanks for your time.
