PC won't boot, fans go crazy on start up
Hi guys, I need some help diagnosing my PC. It's an Alienware Aurora. It won't successfully boot anymore. It was working fine a couple days ago and I haven't made any hardware changes recently. I usually leave my computer on all the time and today I came back to find it unexpectantly off. I turned it on and this is what happens:
1. Fans go crazy and stay on
2. It eventually got to the "Windows did not shut down properly" screen
3. I chose "Start normally" (fans still going crazy)
4. It tries to load, takes awhile, then says it can't boot with a screen for "repair startup util"
5. I chose repair, it showed a progress bar for a second that doesn't get far, then just shut off
At a few moments the fan did cool down, but just for a second or two, then ramped back up to max.
What could be the problem? What should I do next to diagnose?
Thanks!!
