Dell / Xps l501x

Specs: Windows 8.1, Intel i5 /4 GB RAM
I have a Dell XPS L501x laptop [[ G9P88BS ]]. Two weeks ago it automatically turned off. I thought it's overheating problem so I let it cool down for a while then tried to turn it on. There was no video and I heard series of 4 beeps. I picked my phone and found that it's a memory read/write failure. I opened the laptop back and took out the RAM and placed it back as I thought dust might have caused the problem.


As soon as I pressed the power button there were no 4 beeps but the display was still missing. No CUP light but fan and optical drive were spinning.


I took it to a service centre and they solved the problem, they said they had rewritten the BIOS [ I didn't give it any thought well I was glad that laptop was working ]


I came back and run the dell system utility to identifying any common issues remaining. When program was in the middle of the scan, BOOM! it automatically turned off.Well I, opened it and did the common people do [[ take out the BIOS battery- Hold the power button to drain the residual power- place everything back]

and it started with the following:

Bad RAM can cause a mix of problems, see here:

I have known it being the reason for reports of registry issues - Microsoft pulling the nearest error message out of the bag that might or might not fit.

Always pop back and let us know the outcome - thanks

Try new RAM, if existing RAM was bad (as indicated by the beeps) it's no good just taking it out then putting it back. You should have binned it and bought new modules.

Thanks, I will buy a new one. [[ 8 GB will do right? ]]

I have one more doubt...as there are two slots for RAM modules..when I place my 4 GB RAM stick in the bottom slot ..it gives the error but there are apparently no problem when I used the upper slot for the same RAM. any idea?


One silly doubt, where to find the new RAM for this model...any trusted places or just Amazon?

Those systems have two banks of one, so you need to have the RAM in the top (which I think is the A slot) if you have only one stick.

Crucial is a reputable place to purchase RAM, so I recommend that.

Did you clean the RAM edge connectors with a pencil eraser? Oxide is a common issue and I usually pop the sticks in and out a few times to clean any oxide off the sockets too.

Always pop back and let us know the outcome - thanks

I will do that Derek :D
Tho I think a new RAM will save a lot of trouble xD still I wish to experiment how long I can go with this, hope this doesn't mess with anything else?

Can a bad RAM cause other problems?
