Xiaomi Mi Mix 2 review
Not sure why but my PC has slowed down all of a sudden and runs painfully slow no matter what you ask it to do. Ive run all virus, adware, spyware etc checks and found nothing. The easiest of tasks take an age to complete, including start up and shut down!
Any ideas please?
Thanks in advance.
back up anything you don't want to lose and use your recovery disks to take the computer back to factory settings.
if you don't have any recovery disks, do a system restore go back as far as you can, then make some recovery disks and do the above.
that will do it.
Also run a Disk Cleaner - too may temporary files can cause huge problems.
My favourite (and much better than the Windows one) is Wise.
I also use their Registry Cleaner.
Also it might pay you to let us know the general specification of your system, and what OS and AV you run.
Hardware issues can also slow a system down - such as certain memory module faults, which reduce the amount of RAM in the system - and disk drive faults, where excessive rereads occur due to a failing drive.
Check what's using your CPU by opening task manager. Right click task bar and select task manager or CTRL+ALT then press DELETE.
If everything you try doesn't help, may be best to reinstall & start afresh. Backup everything before you do so though. Also make sure to have your Windows Product key to hand. G
Another thing to ckeck is how full your hard drive is. Before you take drastic actions check drive and uninstall programs you rarely use, run cleaners as suggested above and see if it makes any difference.
As already asked, do you have plenty of free hard drive space, how much free as a percentage of the overall drive size?
Installed a lot of programs recently that may be running at startup?
Also have a look in your startup tab in msconfig, many items listed? That's Start, Run, type msconfig and OK.
Also been asked, any big user of cpu in task manager processes tab? Many items listed in the processes tab?
Any items in red error or yellow warning signs in event viewers Application or System tabs? That's Start, Run, type eventvwr.
a) Clear out all temporay files and folders -- use Crap Cleaner click here
b) Scan for malware spyware and viruses --Free Anti Spyware :-
Adaware click here
Spybot S&D click here
Spywareblaster click here
a2 click here
Windows Defender click here
Free Antivirus software
Avast4 click here
AVG antivirus click here
c) Clean the registry -- Free Registry cleaners :-
RegscrubXP click here
Regseeker click here
TweakNow RegCleaner 1.3.2 click here
Easycleaner click here ( Use with care, It advises you to back up the registry first, this is a good idea as it cleans rather aggressively. )
d) Pagefile (Virtual Memory) -- Rght click MY Computer - select propeties - Advanced tab - Performance - advanced tab - Virtual memory click change, you can put the page file on a differnt drive (if you have one), click custom size and set Initial size to one and a half times the amount of memory you have fitted i.e. 512MB memory = set to 768MB, set maximum to double your memory amount i.e. 512MB memory = 1024MB click ok.
If your hard drive is full and there is not enough room for the pagefile this can slow down, freeze or even cause the PC to crash (restart).
e) Cut down on the programs that load at startup -- Start - Run type msconfig - startup tab- untick everything except for firewall, antivirus and antispyware
and the services that run in the background. click here
a) Hard drives / IDE Channels:
i) Check the transfer rate, you need to have the transfer mode set to DMA not PIO.
Right click My Computer - Properties - Hardware - Device Manager - Expand (click the + ) IDE ATA/ATAPI controllers right click Primary Channel - Advanced Settings Tab -
If transfer Mode is PIO then follow the instructions at click here to change.
ii) Check for errors and defrag your hard drives -- My Computer - select drive - properties - tool tab - Error checking / Defragmentation.
ii) If you are using Windows XP, it's a good idea to convert your system drive to the NTFS file system if you have not already. In addition to providing numerous security and data recovery improvements over FAT32 (the file system of choice for Windows 9x/ME and XP Home) it can also speed up your system slightly.
In fact, the only real reason for sticking with the FAT32 file system for any of your data is if you have more than one operating system on your PC and the other OS's can only see FAT32 partitions (as would be the case with Windows 98, for example, which is incapable of reading NTFS data).
To convert your drives to NTFS:
Right click on 'my computer' and select 'manage'
From the computer management window, expand storage and select 'disk management.'
Using the 'file system' column of the upper pane of this window, you can easily check what file system each of your logical drives is using. Make a note of this information.
Now open a command prompt window by going to 'start\run' and typing 'cmd'
To convert a disk to NTFS, type 'convert (drive letter): /fs:ntfs'
So for example, if you were going to convert your C: drive, you would type 'Convert c: /fs:ntfs' at the prompt.
Obtain the newest drivers for your hardware
This may seem a bit obvious, but keeping your system's drivers up to date can give both your performance and stability a boost. Video card manufacturers release updates especially often, and these can often give "significant boosts" to gaming performance as video card in question is "optimized."
Don't neglect the other components of your system either. Your motherboard manufacturer may have released newer versions of its Input/output drivers for your board, and sound cards and other peripherals can also benefit from newer software.
Add more physical memory, this of course means opening the "box" and fitting a memory module, make sure you buy one that is suitable for your PC. Crucial .com click here will guide you through the process of slecting the correct memory. click here for a guide to fitting memory.
