I'll start with the TL;DR part:

TL;DR

  • HP TX1000's WiFi stopped working one day. Then it began to (suddenly) turn itself off.
  • When "cool", it turns on and I get bios but it turns off after 5-6 seconds.
  • If I turn it on right afterwards I'd get no bios/post or anything, just a black screen (not even backlight at all) and it would sit like that for any amount of time, it won't turn off suddenly. Fan is at full speed but no overheating/hot air coming out of the vent can be felt though.
  • If I turn it down and let it that way for about 10-15 minutes it'd turn on again (with bios and everything) but it'd turn itself off after 5-6 seconds again and it goes on like that.

Is this a temperature related problem? Would cleaning it completely solve this issue? or is it broken already?

Edit:

  • I cleaned everything thoroughly and replaced the thermal compound
  • Now it turns on everytime correctly but shuts down at boot.

Here's a video that pictures this issue in its latest state: HP TX1000 Series boot failure

Update:

It turns out that it wasn't overheating, the problem was a faulty BIOS or motherboard that would make the computer turn off itself just at the moment it tries to boot from any device.

That sounds really fast for just generally overheating. You should definitely try to open it (or get someone to open it who knows what he's doing - generally the better idea unless you're "that one") and check the fans. Even while being full of dust I'd say it shouldn't overheat that fast, unless there's some serious cooling issue (like coolant/fan disconnected from the CPU for whatever reason). Also, while doing this, are you on battery or is it plugged in? –  Mario May 13 at 6:43
    
I've already checked the fan and the thermal compound and they are ok, I let it stay at the BIOS for 5/10 minutes and it didn't shut down or anything, temp was still normal, but at the moment I tried to boot from a live stick it suddenly shut down, I tried again with the hard disk and even tried without any drive at all and the result was the same: It shuts down trying to boot an OS. It's getting a lot stranger. What could be the cause? Is it a faulty firmware? (Somehow it now turns on correctly at the 1st attempt - no blank screen at all) –  arielnmz May 13 at 8:08
    
Might be some hardware problem screwing up something. What if you try to disable as many onboard-devices as you can in BIOS? –  Mario May 13 at 8:10
    
It has its defaults set: Dedicated video mem. 32 MB, Virt. Tech. Off, CD-ROM, Floppy and Internal adapter boot are all off. I also have to say it lists drives perfectly, it just shuts down trying to boot any of them. –  arielnmz May 13 at 8:19
    
As you said your WiFi stopped working, I'd suggest try disabling that, then try again. If it isn't cooling (check temperatures in BIOS), then it sounds like some hardware fault you probably can't fix on your own. –  Mario May 13 at 8:21
