  • Yeah it sounds like you’ve eliminated all of the most common possibilities. All of this narrows it down pretty far:

    Both when actively using it and leaving it idle when I’m away doing anything else.

    The screen freezes the last shown image on it.

    Every time the computer is on it will eventually freeze.

    Yes both windows and Linux.

    Haven’t tried booting a live OS.

    It’s likely not an SSD issue because I have booted from two different ssds.

    If you’ve already swapped the SSD and reinstalled then the live OS would probably be a waste of time, it really just verifies that the fixed disk is not the source of the problem (although it could be something like the SATA bus, in which case swapping the drive would be irrelevant - low probability on that though).

    The barebones test is definitely a good next step. The only other thing I’d suggest is checking the socket real carefully with a flashlight and a magnifying glass (I know you said you checked it already, not clear if that was just a quick look or a full examination). Also make sure the socket itself isn’t cracked or damaged in some way that might cause it to flex and not fully contact the CPU when you lock it down, and that all the pins lift up like they’re supposed to when the lever is folded down.


  • I’ve been having an issue with my computer deadlocking after roughly 10-30 minutes of it being on. The simple test was when the computer froze up it didn’t register any inputs, caps lock didn’t change any lights on my keyboard, the computer fans still ran, sound just stopped instead of tonally rattling my headphones like a regular bsod.

    What are the conditions at the time of the crash? Are you actively using it? Is the screen blank, or frozen showing the last activity? Does this occur every time the computer is on, or intermittently? Does it happen in both Windows and Linux? Does it happen if you boot a live OS and leave that running for awhile? Have you done any SMART checks?

    Just to further clarify the symptoms, is it true that the following all appear to stop working at the same time?

    1. Video out
    2. Audio out
    3. Mouse in
    4. Keyboard in

    Also what are your mouse and keyboard like? Are they wireless? Is there anything else like a USB hub between them and the motherboard? (or maybe an internal port extender inside the PC case for front panel ports or w/e?) Have you tried a different mouse/keyboard just to check the simple stuff? Is the mouse optical sensor still on after the crash (still getting power)?

    It would be useful to strip your motherboard to just the CPU and boot to UEFI/BIOS with only the monitor and keyboard attached. (You might need to have 1 RAM module installed to get the motherboard to start - this depends on some specifics of the chipset and the POST test for your board - install the RAM only if you can’t get to UEFI without it). Does the crash occur in this state?








  • Oh, it’s not, the difference is that the SVG is an unexpected delivery vector.

    The script on a website might change over time, might be blocked by an extension like uBlock origin that prevents sections of web code from loading in the first place. You can block a website’s JS with an extension that specifically does that, like jshelter. A malicious SVG is static, the malicious code is malicious forever and is embedded in the file. A browser extension can’t selectively block pieces of the file from loading.

    Script blocking extensions prevent web page code from loading, but they don’t prevent the application from executing JS. If you open an SVG, the file is downloaded locally (it’s not web code) and the JS in the file will execute locally, with the same permissions and file system access as the user opening the file.





  • YSK: SVG files are a security risk. Be careful where you get them from and how you handle them.

    Basically, an SVG can contain JavaScript. If you open an SVG in an application that can interpret the JS (e.g. a web browser) then the script will execute (just as with a malicious PDF), at which point it could download other files (malware) or perform any other function that the application has access to (creating, editing or deleting files on the hard drive) because you gave it permission to do that by opening the SVG. Effectively opening an SVG in a JS-capable application is the same as allowing a stranger to run arbitrary code on your computer. You might as well go around the Internet wearing a “please hack me” sign.

    Downloading an SVG to your hard drive directly should be relatively safe, and opening it in a graphics program that does not execute JavaScript should have no risk, but viewing random SVGs in a web browser is a real hazard.
