Computer suddenly very slow

[Webnerdz]

I'll start with the specs: CPU: i5 6500 MOBO: Gigabyte H170-HD3 RAM:16gb hyperx fury 2133mhz GPU: GTX 960 FTW 2gb PSU: seasonic 550w gold SSD: Sandisk ssd plus 240gb HDD: hitachi 1tb. So... my problems started last week when I was came back to my computer after having dinner and the monitor screen was black and read 'No operating system found, disconnect any drives without an os'(something like that anyway), so I turn off my pc and disconnect my hdd and leave my ssd plugged in, windows boots and everything is normal, turn off the system and connect my hdd back, everything fine still. A few days later I have a power cut which shuts down my pc and the day after the os isn't detected again, so i think that's weird, ill do what i did before and it should work again. It works again kinda... Now my PC is painfully slow and simple apps like chrome and settings are not responding, in task manager the disk usage is very high most of the time and I don't know why. Is my ssd corrupted/damaged? or has a windows update messed up performance? I should probably mention that all temps are fine at 25 degrees average.

What program do you recommend for checking ssd health? Any help is appreciated.

Try a Virus scan first. If that comes up clean go and download CrystalDiskInfo download that and see the health of your drives.

sounds like a virus. but it could also be a failing drive, try malwarebytes and see if thats a problem or CrystalDiskInfo if its a drive issue.

First as @beach_boy98 Said Do a Complete PC Scan For Viruses then Download CrystalDiskInfo Check the Health of your Drives, that should Give a Clear Indication

 

Otherwise if your on Windows 10 you Can Send your PC back to a time it Was Fine:

 

 

 

But Do Everything above First!

 

Restoring your Pc to a Past Date makes it so you don't have to Completely Reinstall Windows,

Yeah forgot to mention did a full system scan, it removed a couple of files that could've been viruses from utorrent, which i have never installed so i have no idea how they got there. Anyway no threats detected anymore but pc is still slow, gonna try crystaldiskinfo tomorrow.
