Computer suddenly honorificly slow for seemingly no reason

Title should be horrifically.. damn auto correct.

Hey guys.

So I turned my PC on today as usual, logged in to find it logged into the metro start screen... not the desktop like I set it to as soon as I installed windows 8.1 for the first time.

So naturally, I went to the desktop. Only to find literally nothing had loaded. My wallpaper was there, but no desktop icons (yes I have a few sadly.. not totally clean), no problems in the quick tray, nothing running.

Strange... pressed ctrl+shift+esc to load up task manager... nothing.... Ok..... Click start button... nothing... At this point I figure its a weird crash, reboot with the switch on my case.

Exact same thing happened next boot. I think my brain melted (I rarely have problems with computers) So I went downstairs made a coffee came back up, and found that MSI afterburner as well as google drive, OneDrive and qbittorrent had loaded... but nothing else (I have maybe 25 programs that start on startup)

I checked MSI after burners and it looks like only 1 core of my CPU is being used at any one time, but it switches randomly... very strange behaviour.

My computer is beyond horrifically slow, I managed to open Intel SSD toolbo after waiting 10 minutes for it to not crash windows explorer and it said it was in perfect health. Haven't managed to open anything else so far... any ideas?

Ram, heat, virus/malware

Thanks for the fast reply. I didn't think about RAM, I haven't tried taking sticks out yet (I run 4 sticks of 4GB patriot RAM). Will give it a shot in a sec and run memtest after that... I guess I thought my RAM was fine since I have had it now for over a year and it works fine, afaik RAM tends to break fast or not at all... although if it is RAM then its an easy fix I guess... lets hope <3

I run panda antivirus and I am pretty careful so I doubt its a virus/PUP but I will ofc scan in case, happens. Once I can load up malwarebytes that is... D:

Oh right.. nah everything seems really underutilised.. RAM is at like 2gb used, DISK I/O is at like 0-5% even on my SSD, CPU usage seems locked at 34%... according to MSI AB its 100% on a single core for a bit before switching.

I thought t was my SSD to start with ofc, given disk I/O is usually the problem for laggy computers but right now I am baffled lol

Hey guys, thanks for the replies. I have been playing around most of today and figured its either my SSD or the windows install (booting from a fresh windows install on one of my other drives, and booting from my GF's SSD is fine). Right now I am trying a last ditch effort, a restore from AOMEI backupper. If it doesn't work after this then the SSD must be ed.

According to intel SSD toolbox its S.M.A.R.T says the uncorrectable error count has risen from just over 1 million (checked this morning just before I wrote the first post) to just over 13 million as of a few hours ago. It says this is fine and doesn't flag as a caution, but doing 12x what its done in 3 years in half a day seems pretty suspicious to me. CHKDSK didn't find anything bad though so idk... I guess I shall see after this full partition restore finished in 30 minutes.

in a command prompt (run as admin) type in following

sfc /scannow

it will check the windows files against a known hash of them and fix the ones that are broken if it can.

For things like this, it should be one of the first things to try out after eliminating the obvious hardware faults.

Ah, the inexplicable OS crash.

Many drive makers offer Acronis backup for free, which I can recommend as effective. EaseUS is also decent, for free. I'm personally never at a point where I don't have a backup of my OS, and I've practiced, many times, restoring the OS. I also insist on a separate OS install, bootable from a menu (usually the UEFI menu in my case) for overclocking and comparison.

At least you've identified the main problem.

I've had heated arguments on other boards about the durability measure of SSD drives. Many insist it's a non-issue, but I disagree. The long running durability tests indicate drives can have read errors but still function well. The observation that write usage has dramatically increased may be associated with Windows attempting to repair itself.

I far prefer the Memtest which boots from USB or DVD instead of the Windows version. As to RAM failing, I have an anecdote which would be applicable if your RAM were the culprit. My previous machine wouldn't boot after years of reliable operation. What I found, after much investigation, is that gunk had accumulated (a damp lint) on the RAM sticks (these were without heat shields). It was just conductive enough to foul the RAM. After a cleanup, the RAM continues to operate flawlessly for years. I live where 72F is Winter, and humidity is rarely lower than a sauna.
