As I said I am a newbie to linux.My os is linux mint 17.2 refaela 64bit full install.I must have done something wrong or got a virus but some times when I am in a program it will lock up and it is random does not mater the program or when or what I am doing it just locks up.The only way to get out is to restart the system and on loading the screen turns red and seas ubuntu 14.04 and has a error but go by so fast I can not read it. But it does load. Normally the screen is black with the 4 balancing dots when it loads.Linux is not supposed to get viruses.From what I have seen on the forums you guys know a lot about linux.So if anyone has a idea or if you need moor info on my system let me know and how to get I will thanks

Where exactly are you doing this, shell or GUI? Does the whole machine freeze or just the program? If you're doing this in a GUI, can you still switch to a shell with CNTRL+ALT+F2,3,4 (one of the function keys from F7 upwards should bring you back to your GUI). If not, that is, if your whole box hangs, then IMHO that would indicate a hardware or driver issue, In that case, get your set of screwdrivers ready.

As I am new to linux and do not know all the keyboard shortcuts,so I will check that when it happens again. It is random but it is in GUI.Is ther a web site to get keyboard shortcuts?I think it just locks up the program but I will know more when I try F-keys and or shell.by shell you mean terminal?thank you very much

The description of your problem in your first sentence above is a classic sign of overheating. Clean it out, at least get the dust out some way.

If you have Mint installed, I don't know why you would be seeing a screen showing Ubuntu 14.04. Mint is derived from Ubuntu but still, you should not see that. Is Mint the only operating system you have installed.

The likelihood that you got a 'virus' is substantially less than that you did something wrong. Is this a new install of Mint? Has this been happening since the install or did it initially work well? If the latter, what changes were made just before you got the problem?

To Yancek I will try cleaning the box.I do not know why it showing ubuntu on startup it was working fine at first and do not recall the first time it happened but it is random.So I just have to keep an eye on it to get more info.Thank you

Ok I cleaned out dust from the box.I did get the locking up to happen with VLC media player but it has locked up randomly with denfront programs I have screen shots.It is the system that locks up.While I was looking up keyboard shortcuts on my tablet it did popup a error box (107556 pic) after about 3-5min and let me close it.As I get more info I will post it.Thank you

If you can boot Mint or the Mint install CD/DVD/flash drive, get to a terminal and run the command below and post the output below which will give us some info on your hardware. I don't know why you are seeing the Ubuntu screen if you have never had it installed.

thanks

Looks reasonable.

But the fans on the cpu (graphics adapter, motherboard) are actually rotating? If you live on the northern hemisphere and enjoy the same weather as we here in Munich, Germany (8°C/46°F): turn off the heating in your room, open the window and see if that has an effect. If it does, it's a temperature problem.

I live in sacramento CA. (usa) and the computer is in the garage so I don't see it being a temperature problem? and if linux can not get a virus than maybe a bad file or I did something wrong.IF I can get any moor in info let me know.Thanks

I figured out that the system locks up when I have moor than 3-4 tabs open I wonder if it has to do with memory? I have 4g ram and 1g on the gpu I have tested the ram in bios and it is good.How do I test the ram on the gpu? and how do I check and setup cash memory to see if that is the problem? thanks

to jkrobbins:
- marius162 suggested a good test next time the freeze happens: on your keyboard, press "Ctrl"+"Alt"+"F2" together. if this brings you to a black screen with a login prompt, that is a good sign - it means the freeze is not deep. if nothing happens, the freeze is deep.
pressing "Ctrl"+"Alt"+"F7" should bring you back to your (frozen) graphical desktop.
- please also post the output of to all others:
the screenshots mention acpi. maybe add something to boot command?
also i see a fairly new nvidia card, but an old driver:(at least on archlinux, the nvidia 304 series is reserved for the oldest cards.)
and somehow the single core amd sempron doesn't fit.

to jkrobbins:
what sort of setup do you have here? a really old mobo with a fairly new nvidia graphic card?

Does a memory problem have to do with the ubuntu on start up?

please answer the other questions first.

linux mint is based on ubuntu, so it's not too surprising to see their logo.
