hi

my laptop keeps shutting down automatically.
its not necessarily a heating issue because its generally lukewarm when it shuts down on its own.
what happens is that I run a few programs at the same time and hear this growling revviing of my cpu fan and it shuts down seconds later.

hp dv5 windows 7 5 yrs old.

looking forard to your help

thanks

Quick diagnostic primer for 's HP dv5 (reported: spontaneous shutdown while the fan revs and the case stays only lukewarm). Replies so far have pointed at cooling, power and software causes (, , , , ). The checklist below is ordered to isolate the root cause with minimum guesswork.

  • Inspect Event Viewer (Start -> type "Event Viewer" -> Windows Logs -> System) for critical/errors at the shutdown timestamp. Look for Kernel-Power (Event ID 41), BugCheck entries or other logs that coincide with the failure time.
  • Boot a Linux live USB and repeat the same workload. Shutdown that appears under both Windows and the live session indicates a hardware problem; if it only happens under Windows, suspect drivers or software.
  • Run vendor hardware diagnostics (HP built-in tests from BIOS/boot or HP Support tools) to exercise CPU, fan and power checks.
  • Isolate the power path: test on AC only and battery only (if battery is removable). Note any change in behavior or if the DC jack is intermittent when the adapter is moved.
  • Collect Windows minidumps (C:\Windows\Minidump) and record any stop codes; perform a clean boot to reduce background drivers/services when trying to reproduce the issue.
  • Log sensor data with HWiNFO/HWMonitor (temperature, fan RPM, CPU throttle) while reproducing the problem to see whether a thermal trip or sudden RPM/voltage change occurs.
  • Run memtest86+ and a SMART check on the drive to rule out RAM or storage faults that can cause abrupt power-offs.

If diagnostics point to hardware (failure in live-USB, diagnostic errors, or sensor evidence), arrange professional testing/repair of the cooling/fan assembly or power path and back up important data before further testing. If failures are Windows-only with identifiable stop codes, focus on driver rollbacks, BIOS/firmware updates and OS-level troubleshooting. Priority is to preserve data and collect timestamps, stop codes and a short sensor log so the fault can be diagnosed without unnecessary parts replacement.

Hello,

Based on your comments I would say it is heat related. I have had a few HP laptops over the last decade (Compaq and HP have always made a quality product) and what has probably happened is the heat sync on top of the processor is clogged with dust. You can buy a can of compressed air just about anywhere now a days and I suggest that you blow out the dust (with the computer off or you risk burning out the fan motor) through the vents on the back and sides (sometimes bottom also). Blow it out from both directions and I will bet you see some improvement.

virus is there in your pc, it will happend like this.so try to conform about the virus on your computer

Wouldn't be a virus! What he said he is running programs at the same time putting pressure on the CPU and eventually shutting down the pc because there are too many things running at once

Hi!
there are could be 2 problems: with power supplier or heating system
Tell me how lond do you use your laptop? Did you clean it from dust? Do you change thermal compound after buying your laptop?
And also answer for your question: USB fan will not help yoг if the problem connects with power supplier

He said it was a revving noise coming from the CPU i wonder if the CPU is stuffed
