| Windows 10 laptop is super slow (CPU failure?) |

Hi there. I have a laptop running Windows 10 that has become increasingly slower and slower over the past week. I used CCleaner to remove junk files and clean up my registry, as I thought the slowness may be attributed to an over-accumulation of cached files or bad registry (it has worked in the past), but no dice. There are no major processes taking up a lot of CPU or memory usage, and when I ran a SMART test on my drive, it came back clean. I did notice, however, that the CPU speed listed in task manager was a maximum of 2.59 GHz, but was currently running at only 0.18 GHz. I've never seen it so low before. It takes forever to even log into the desktop or do anything now. It's too slow to use for anything meaningful. Any ideas what could be causing the general slowness of the machine? Is it unusual for the CPU to run so slow? Could that be a sign of hardware failure? Any/all ideas welcomed. Thank you in advance.

Maybe it's overheating and forcing itself to power down? Can you hear your fans spinning? My Website! | EAGLE GUI Library Demos | My Deviant Art Gallery | Spiraloid Preview | A4 FontMaker | Skyline!

Ah, good idea; I hadn't thought to check for overheating. Although, it hasn't been powering itself down, it has crashed several times. I'll listen for the fans tomorrow when I get to it again (left it at work). Thanks, Edgar.

I meant 'throttle down', not power down, sorry. It's my only guess. Something's wrong of course, but with XP I'm used to prolonged 100%CPU from svchost and windows update, so I can't really help you with low cpu frequency. Google any help?

My wife's lenovo has started to get slow. I've suspected some crazy updates may have made it dog slow, OR the hdd is silently failing. I got her a new SSD and ram for it, and when I tried to dd the data the first run failed, and that would certainly cause issues with windows. I used ddrescue the next time and it didn't find any errors, but the first run may have gotten the hdd to reallocate the bad sector possibly. That said, I just saw your 0.18Ghz remark, and WOW, the only way i know of an intel getting that low is if its thermal throttling. Clean that sucker out. -- |

I don't think it was a recent update that is the issue. I rolled back a few updates and even reverted to a restore point from earlier in the month to be sure, but neither had any affect. The drive is fine (according to a SMART test I ran on it). The CPU is an Intel i7 somethingoranother. I'll take a closer look later and maybe even disassemble it for an even closer inspection. In the event that the CPU is going bad (not due to the fan making it overheat, etc), is it possible to remove and replace a laptop CPU? I've never had to replaced laptop parts before.

Some laptops have replacable cpus, some don't. Once you get it open, clean everything, and replace the thermal compound on the cpu and gpu, and anything under the heatsink(s). -- |

Might be an idea to boot it with a Linux live CD to see make sure it's not because of driver issues or something. |

Ugh windows 10.... i had a decent PC before upgrading.... all it seems to want to do now is thrash the HDD non stop. Seems SSDs are required at minimum for Win 10 ___________________________________ |

Hard drive failure. Have that on a laptop recently until the hdd finally died on me. "Code is like shit - it only smells if it is not yours" |

Hard drive wont cause the cpu to run super slow -- |

No, it will cause the whole computer to go slower. "Code is like shit - it only smells if it is not yours" |

The problem seems to be the cpu running at a really low frequency. 180mhz. -- |

Try what Gully said, and boot it with a Live CD. If the CPU still runs slow, then you probably have a hardware issue. If not, it's probably a software issue.
