W10 Desktop randomly crashes (no message & power remains on)

September 25, 2015 at 07:11:34
Specs: Windows 10
Problem: Randomly my computer will suddenly just stop working; audio will stop playing and monitors will say no input found. Yet the power doesn't go off (power light on tower still on and fans still spinning). Turning it off requires me to hold down power button. Turning it back on again soon after has it do the same thing almost immediately (on the firmware startup screen, or before I even saw anything once). If I wait ~10-30 minutes it seems to stay on a random amount of time.

First happened 4 days ago. Since I was on a webpage with a lot of flash that was lagging my computer, I didn't think too much of it, despite the weirdness of the "crash", and turning it back on was fine for about 24 hours. The second time I got a little worried, and it crashed again after ~3 hours.

Some notes that may or may not be relevant: I recently switched to W10 ~1 month ago, running a W7 before. Since switch my "disk" seems to be at 100% constantly. I'm one of those people who leave their computer on since I often have a lot of half finished things open. All 3 of my computer fans seem to be working. Computer is 5 years old, and only ever cleaned the inside once 1 year ago. After turning my computer on successfully, I turned off all running programs / background processes I could, and just played solitaire until my computer turned off again before I could finish (twice). I have two monitors (using the HDVI / VGA ports on the back of my computer), and both "lose connection" at the same time as audio. No message pops up before crashing, and I don't seem to get any prompting during startup. There may be error logs somewhere, but not sure were to find them. The computer is dual booting linux on a partition, but I haven't run linux in a month or so shouldn't be relevant.

My thoughts: I'm not in any way a hardware person (despite being a programmer), but my wild guess is that despite the fans going it's related to some wrong in the hardware, wether or not it's heat related (which just seems likely to me since letting it sit awhile has it stay on longer). The fact this happens even during the firmware starts gets me worried since it's way outside my realm of expertise. Since I've had W10 for a month now I feel that removes some possibilities (may not even be related). While I doubted it was related, I installed AVG and scanned computer (nothing important), and did a registry clean (didn't fix the issue as expected).

I'm afraid I don't know my CPU / ram offhand (I'm at work), but I know it's a standard 5 year old hp computer bought from a general computing store for college, and has had no modifications made to the tower.

Sorry I can't be more descriptive about the physical parts of my computer, but as said before not my expertise, although I can find some info if directed to.

If it happens before Windows starts then I agree a hardware issue is likely. You could use this to check temperatures:
http://www.hwinfo.com/
Let us know the temperatures.

If you wish to do a quick malware check these three small freebies often find things that Anti-Virus programs miss:

AdwCleaner:
http://www.bleepingcomputer.com/dow...
(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run the program. Use the "Scan" button, followed by the "Cleaning" button.

Junkware Removal Tool (JRT)
http://www.bleepingcomputer.com/dow...
(blue Download button near top - not anything else on the page).
Download and "Save" the file somewhere. Go to the saved file then double click it to run JRT. It might appear to have stopped at times or flash the screen but sit tight until it has finished.

MalwareBytes:
https://www.malwarebytes.org/downlo...
Download the free version.
Install and Run the program but before doing its Scan go to "Settings > Detection and Protection" and put a checkmark in "Scan for rootkits". Quarantine anything it finds.

If anything is found copy/paste the associated log(s) on here.

Always pop back and let us know the outcome - thanks

Let's do the Elimination method of troubleshooting first - one thing at a time.

...haven't run linux in a month or so shouldn't be relevant.

You never know - can you boot to Linux to see if the desktop also crash.

Yes, good thought to try Linux, especially as it's there already.

Hey, so my computer can currently only stay on for about 4 seconds max now, so I'm afraid I can't really test these options. sorry!

If you leave it off for a long while does it stay on for longer afterwards?

Does it turn off before it makes it to Windows?

It's possible it is choked up with dust but that is one of many possibilities.

Always pop back and let us know the outcome - thanks
