Laptop fails to boot/sporadic sprees of freezing

    Even if I detect a memory issue, since it's a laptop, what're the chances anything can be done about it?

    Replace memory stick.

    ...Even on a laptop? I've opened up my desktop to change things out plenty of times, but I've never even attempted it with my laptop.

    I made the memtest USB, plugged it in, and after a number of failures to boot, got:

    ERROR:0254: System NV7 Volume checksum bad - Default configuration used

    Press <F1> to Setup

    ..And then it froze.

    Got the memtest to run, makes it through 1 hour / 1 pass, but first time through, it failed at 1 hour. Froze, I think; WallTime stopped moving, even though the flashing bar under L2 Cache kept blinking.

    Trying to run it again.

    It'd probably be best to try one stick of RAM for right now. If the first one fails, try the other one. (Unless you only have one stick).

    What's your computer's make/model? I can get a tutorial if you want to attempt to open the case and try to solve it yourself. UNLESS YOU HAVE A WARRANTY. If you have a warranty currently, please tell me. If that's the case or you don't want to try yourself, a service repairperson will have to do the memory testing and/or replacing.

    At this point, we're not getting very far.

    How's this going?

    Pretty badly. I tried to run memtest a few times, but it never made it past one pass before freezing, at about the ~1hr mark.

    I'm on a lenovo T500 thinkpad; it's a few years old by now, so I'm sure hardware's gotten much better since the time I bought it. Hell, I think it's running off a core2duo or something. The warranty's long gone by this point, though.

    That's a pretty good sign the memory is bad. I would recommend buying new stick of RAM. If you have tested to see which one was bad, by trying them one at a time (if there is more than one stick, that is), then you should know which one needs replaced.

    If you need help finding the manufacturer, or other reason...Go HERE and run the Crucial online scanner.
    Press the System Scanner tab on the big image on the homepage.

    This will give you the exact memory configuration for your system. You do not have to buy the memory from there, but write down the information and if you need assistance in purchasing the upgrade memory I can assist with suggestions also.

    I'm assuming that I'd need to open up my laptop to try and test the sticks individually; since RAM - for desktops, at least - tends to be sold in pairs, would it be worth the effort to try and test which stick is dead, or just not even bother and get a new pair altogether?

    On the other other hand, one of the issues I had with my desktop a while back was that one of the RAM slots in my mobo was flat-out broken; putting any stick into it caused the entire mobo to fail to boot. Is that sort of thing expected with age, or more on par with freak-accident-no-we-don't-have-any-idea-why-that-happens?

    Test both, if you can. If you really want a clean start, go ahead and purchase. But, my point is, you'll need to make sure how many of the sticks you have in there. If it were me, being the performance junkie I am, if I was to go with all new RAM, I would get higher amounts of RAM (since now it's cheap, especially for older models). :)

    Anyway, I'd say that broken mobo part (RAM slot) is probably defect/freak accident. :p

    Heh. At this point, I'd sort of rather go for the clean start whenever I can manage to actually get my laptop online long enough to run the damn scan. I used it for about five minutes earlier today, then it decided to freeze, and I haven't been able to get a successful boot since.

    Ugh.

    Woohoo, managed a successful boot, ran the Crucial scan, and got the specs for some sticks of RAM. How hard is it to fiddle around the insides of a laptop - and if I accidentally mess something up, how easy it to FUBAR it all?

    It's not difficult. Once you order the RAM, look up a tutorial on how to install it on your make/model. As long as you do it carefully, and know how to put it back together after taking it apart (because obviously it goes back together the same way it came apart), you shouldn't have any issues.

    For one of my laptops, I usually have like three steps to do: take the communications door off, flip up the clamps for the RAM, and remove it.
