Poor performance with my PC

[Cuddles]

Been having this issue for the past couple of months and its been getting slower over time, I've made a reddit post about it but I'll post it here.

Computer Type: Desktop, custom built

GPU: GTX 1080 TI

CPU: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz

Motherboard: ASUS MAXIMUS VII GENE

RAM: 16 GB

PSU: EVGA SUPERNOVA 850 G+

Operating System & Version: Windows 10 x64-based PC 10.0.18362 Build 18362

GPU Drivers: Nvidea build 441.11

Description of Problem: Computer performance being getting slower over time for the past 3 months, before it was completely fine. but now it takes about 5 mins just to restart or shutdown, this also affects programs as well

Troubleshooting: I've tried doing all the recommendations I've seen on tech websites, which are the following of which i remember:

• Disable a couple of start-up programs

• Did a dsim system check with cmd to check and resolve any system files that are missing or corrupted

• cleaned out my pc to get rid of any dust that may be the problem of the issue (was unable to clean the cpu in case I cause additional issues)

• changed CleanFilePageAtShutdown in the regedit editor from 0 to 1

• changed my performance plan from recommended to best performance

• changed my power plan to edit the cpu usage in "edit power plan" so the minimum is 5% (was 100%) and the maximum to 90% (was 100%)

• Uninstalled a couple of programs that I barely used

• Uninstalled Geforce Experience as I saw it can cause issues with performance

• Did both a quick scan and full scan of my computer with malwarebytes and with windows, windows did catch something during its 3 hour long full scan BUT it didn't solve the issue.

I'm at lost as to what to do now, the only thing coming to mind is calling pc specialist as that's where i got my custom bulit pc from.


Edit: I freed nearly 300GB on my external hard drive from 684GB to 964GB in hoping that would cause the issue to subside a little bit and it lowered the RAM a bit. But my issue is still persisting without a change at hand.

I also did a Memory Diagnostic check which ended up with no problems detected so I am officially stuck on what to do.

Hi,

What storage devices does your PC have? What free space do you have available on C:\ drive? Is your boot drive a hard drive or an SSD?

[Rumpelcrutchskin]

Constantly longer boot and shutdown times sound a lot like corrupted files in Windows OS.
One thing you have not done in this list is clean install of Windows with reformating entire OS drive.
Maybe your only resort left at this point since you have done pretty much everything else, just remember to back-up the stuff you need to your external HDD.
If you dont have SSD then it`s probably good idea to buy a cheap 240-250 GB SATA SSD (like Crucial MX500) and install Windows 10 on that.

sorry I should've said, I've got a

Samsung SSD 850 EVO 250GB

and my external hard drive is a

TOSHIBA SCSI DISK DEVICE

which is almost 2TB

You should also look at whatever storage you are using for OS using crystal disk info (or any other software that reads SMART), it may be a sign of trouble with HDD/SSD os is installed on.

[Cuddles]

ok i'll try that to see if anything pops up

Did you run chkdsk /f? (Not /r.)

I didn't know SCSI was still in use except on servers or for internal archival tape drives.

No, I didn't see anything to do with that

How much free space do you have on the SSD? SSD drives will slow down when they fill near capacity, which will then lead to issues with the paging file and issues updating Windows and any Apps you have installed. On your OS SSD drive you should leave at least 30-40 GB free

I also vaguely remember something about some samsung evo ssd-s having issues with read speed degrading over time for data that was not re-written for a long time. Not sure if it was 840evo or 850evo, might be worth googling.

I currently have 85.2GB out of 224GB

I've just done the crystal disk info for my external hard drive which this was the result

and this was for my SSD (C:) drive

I have no understanding on what the program does though

[L37]

Crystal disk info, not crystal disk mark. It reads values from internal hdd/ssd memory regarding its state.
Crystal disk mark is just a benchmark... well, at least now we know your ssd seems to be working fine in terms of read/write performance for new data.

What did the antiviruses catch during the scan? How many things were they? and what were they?.

It was Trojan cryptinject within my windows folder

but other than that there was nothing

Before you call the pc specialist, try re-installing windows and formatting the drive. That virus may have had something to do with this.
