but what if when you just turn on your computer and it takes for ever to fully load but when loaded its fine and fast


I just fitted a Samsung SSD into a Aspire V5-571P and was unimpressed with the performance.

It ran fast on battery set to the standard “Better Performance” but when on mains I had to set it to “Best Performance” to maintain speed. Removing Acer power plan had no effect.



@colsearle, what was the computer (not battery) performance rating before you installed the SSD?

-Your laptop could be slow because it can be affected by a "Virus".

You can use Adwcleaner to find some problems or virus on your laptop.

And CCleaner for delete temporary files, registry error etc...

-Your laptop can be slow because it can be dusty.

You can remove the bottom panel and clean your motherboard from any dust.

-> A laptop with lot of dust will be hot and will be slow.

-If you move with your laptop running you can provoc some damage to your hard drive.

-> Bad HDD is a cause of slowdown laptop

Several factors can cause slowdown on your laptop

pretty much nothing is set to start up i disables them and i cant access my bios

my laptop is a acer v5-571g


My process. When booted, open a CMD prompt or Powershell as admin.

run CHKDSK C: /f. It will ask you if you want to run it on reboot. It won't run otherwise. If you want to see if there are errors on the HDD, first run it without the /f. It will run without a reboot and will tell you if it found errors. If it did, rerun it with the /f. Then run SFC /scannow. It will either tell you it didn't find problems, found problems and fixed them, or found problems it could not fix. If problems were not fixed, run dism /online /cleanup-image /restorehealth

If none of that works you likely need a new HDD. But b4 doing that try running MBAM to see if there is a mining virus.


Hey Stingzy!

Without knowing more details about your computer, the first things I would look at are...

* What are the programs set to start when Windows starts? This is mostly likely a long list of programs that you don't care to need when Windows immediately starts up. You only need them when you need them, so remove them from the list.

* Could be your bios settings aren't set for quick boot or have some extra testing during post -but I'm inclined to think it's the first thing I mentioned.

Hi The Fan!

I would have never thought that hard drive

speed could affect the performance of a system,

but it certainly can.

However, the more common thing in Laptops

and Desktop computers is that the RAM is being

eaten alive by junk.

Here's what I would do to clean up your system:

1. Download and run CCleaner.

I would just get the Free Download (desktop version) for now.

With the program installed:

> Click on Analyze (once done) click on Run Cleaner

> Then click on the Registry tab > click Scan for Issues (once done) click Fix selected issues (don't worry about backing up your Registry if the pop-up comes up)

2. Download and run Malwarebytes

Again, just download and install the Free Download for now.

Open the program and then click on Update to make sure you have the latest for the program. Then close the program -don't run the cleaner yet.

The tricky thing here is putting your system into Safe Mode before you run the cleaner. Otherwise, malware has a nasty habit of hiding itself in the soup of Windows running in Normal mode.

Here's a Microsoft article on how to Start your PC in safe mode in Windows 10.

> Put your system in Safe Mode

> Open and Run Malwarebytes

> Remove any and all items Malwarebytes finds

> Restart your system

> Take your system out of Safe Mode & Restart into Normal mode -should it boot back into Safe Mode.

At this point, you will have dealt with 90% of the common 'slow down' issues. If your system still has issues, could be hardware issues. i.e. Hard drive needs defragging, RAM going bad, overheated components, etc.

My bet, though, is you're good to go after running the above programs.

Warm regards,

There are so many reasons for laptop running slow. You may troubleshoot it as follows.

1. Check the system updates to see if it can be upgraded.

2. If too many programs are opening simultaneously, your laptop will speed down.

3. Check if the laptop is overheating.

4. Virus and malware may be the cause for it. Run anti-virus scan to remove them.

5. Update the outdated drivers.

6. Check hardware issues. Defrag hard drive to optimize it.

Computers run slow for a few reasons. The FIRST thing you want to do is the easy things.

B4 you start, define WHEN it runs slow. On boot, on the internet while browsing, when running a specific app…..

1st - run TFC - download from here and run from desktop = this cleans out temp files, caches, etc. Some malware might be residing there.

2nd - run CHKDSK = open a CMD prompt and type CHKDSK C: /f = scans your HDD for errors. A major cause of slowness.

When you run this, it will ask if you want to run it after a reboot. Answer yes and reboot. If you have other partitions/drives do the same for them (change drive letter). They won’t require a reboot.

If you just want to see if there is trouble on C: do not enter /f and it will run without a reboot and tell you if there were any errors. You then need to run the /f to Fix the errors.

3nd - run SFC = in the same command prompt type SFC /SCANNOW = this will fix any system file errors

If it comes back saying it found errors and could not fix them, then you will need to run DISM

You must be online for this to run

DISM.exe /Online /Cleanup-image /Restorehealth

All of these will take a long time, especially CHKDSK if it finds errors. Just wait for it. I have had it take all night to finish.

At this point, test it. If it is still slow you need to run a complete AV scan.

After that, if it is still slow, boot in safe mode to see if it still runs slow. If not, then you have an app that is using a lot of resources.

Open Task Manager to see what it might be and close any that are using a lot.

If it is still slow, a RAM upgrade might be needed. This would be indicated if it runs slow with your browser or other app.

Lastly, things change. You may have become accustom to a newer computer and are comparing yours to that. If so, you can upgrade to an SSD. that will significantly speed up your boot and lots of other things.

good luck
