Task manager?

Well, maybe this opens up the possibility of a virus again (I'm just taking a stab in the dark, I admittedly don't know much about the internal workings of the PC): all of the processes shown in task manager, summed by hand with a calculator, add up to 218 MB, while it says I'm using 23% of a total of 8 GB (=1840 MB).

Make sure you're displaying processes from all users. Servicehost in particular chows up the RAM.

I am.

EDIT: It seems not to be a memory leak over time - instead it's as though a substantial chunk of memory isn't even there from startup onward. CPU and hard drive are normal/healthy, too - there's just a big RAM problem.

EDIT 2: I think I've solved at least one of the problems. Will keep an eye on things from here.

You should test it with ram from another computer, or just try re moving ram sticks one by one to figure out if one is bad.

Edit: or actually, just use memtest.

Okay, yet another update: I've installed Firefox and it's exhibiting none of the (multiple) issues I was running into with Chrome (so far). Once again I'm not sure from either a technical standpoint or from using it long enough, but I'm looking into the possibility that it's a problem with Chrome. A few searches indicate that "Chrome freezing up my computer" in a similar manner is a reasonably common bug report, and there are several how-to-fix-it guides - I'm just not sure if I should follow through without knowing for sure that that's the problem.

Working on an experiment and trying to eliminate as many variables as possible. Is there a way to make sure that a MinGW implemenation of GCC has no or negligible differences from native GCC in Linux, if both are the same version?

If you want to check your hard drive, btw, you can analyze the SMART diagnostics with SpeedFan.

Not strictly a PC question, but I'm trying to get my Nintendo New 3DS to play music/movie files. A search shows that it's apparently possible, though it's unclear exactly how or what formats are supported. As far as I know, .avi files work but have a 10-minute limit. Apparently MP3 works as well, but I have fewer details on that. I already figured out how to connect my 3DS to my PC and access the files on the 3DS' microSD card, but I don't know where to put files or what app on the 3DS to use to play them.

A quick google says you use "Nintendo Sound" to play the mp3s and you can put them anywhere on the SD card, although there may be a 100 song per folder limit (not an issue if you have a folder per album, but is if you want to just put all your favourite individual tracks on).

Nintendo says:

Playable file formats are AAC-files with .m4a, .mp4 or .3gp filename extensions and MP3 files with .mp3 filename extensions.
Compatible bitrate range is between 16kbps and 320 kbps.
Sampling range rate is between 32 kHz and 48 kHz.
Copyright-protected music files can not be played.

Here's a great one. I bought a new computer in December running Windows 10, worked great up until today. I go to bed at 10:30 AM, everything's fine. I wake up at 2:00 PM and I'm greeted with a blue screen that claims error oxc000021a has happened. Then it just restarted itself, and kept doing it over and over. I drug my old PC out to look it up, all solutions say try Easy Recovery. I bought the program, installed it on a USB, and attempted to fix the new PC with it. I got it to boot up, it claimed it fixed it, yet all it did was break the infinite restart cycle. It still gives me error 0xc000021a.

Does anyone know how to fix this? I don't want to call this thing a brick after only two months of use.

You either have a fault or a virus. That stop code means that one of the core windows system processes has stopped (e.g. crashed) which they don't do by themselves.

Try running SFC /scannow : https://support.microsoft.com/en-gb/kb/929833

[SeriousConcentrate]

I would if I could get it to even boot in safe mode. But it won't. I've tried safe mode, safe mode with networking, safe mode with command prompt, and disabling non-core drivers. I can't get it to do anything but get to the blue screen.

reinstall windows from scratch?

[SeriousConcentrate]

I don't have a disc; the computer was prebuilt and came with Windows 10 already on it. Additionally, it has no optical drive, although if there's a way to fit a Windows 10 install on a 4 GB USB I could maybe manage that.

Sorry if I sound a bit snippy; I've been worrying with this damn thing for about 17 1/2 hours now and I'm a little frustrated.[/understatement] Thanks for trying to help, so far. ^^^;

There is. You can download a downloader from the microsoft site that will make a bootable USB drive for you.
