Pc slow down and almost freezes up

[CDS Wambo]

Hello, since 2 days ago sometimes when i boot up my pc it slow down so much that it takes 2/3 minutes to load even the "password" screen and seems almost freezed up. I have to restart it manually with the restart button on the top of my case and then works everything completely fine. I have 2 HD, one of 1TB where i put all my games and this SSD where is the OS installed Crucial CT275MX300SSD1 MX300 SSD.
I think it could be an anti-virus problem, i have avast, but im not really sure

Have to update my 2 gtx 1070 to the latest drivers

what screen does it hang at?

On both monitors. Now its getting worse. Neither the manual restart work anymore. Did i get some sort of virus??

Update 1:06 p.m.

done a complete scan of the system with avast, no sign of virus. now its working correctly. when was slow the temperature of cpu was around 26/27c°; first gpu around 30c° and the second was already at 50/53c°.

might be a temperature problem? or just some dust inside of the pc?

update 09/05/2017 2:25 p.m.

didn't do that from yesterday, but freezed entire pc while playing. i'm 70% sure it could be high temperature on video card (maybe the second)

didn't update to the latest driver video yet, i have driver 381.89 version. any ideas?

Still doing it. please guys, i don't know what to do

Cloned windows and changed the boot drive from crucial ssd (see above) to a samsung evo 850 250gb. Have to wait some days to see if it is fixed or not

sorry, havent been on the pc in a bit. ok, the freeze during gaming could be a temp issue, but it is not likely the same problem you're running in to on boot. the gpu and cpu should not be seeing load like that during boot. and the temps you've listed are perfectly healthy.

are you booting from the ssd? it could be a boot sequence issue. i had this problem when i upgraded to one. it was booting so fast, some things wouldnt load properly. it took forever to login, and often just hung at the desktop not letting me do anything. have you tried getting in to your bios and disabling fast boot options? trust me, the ssd will boot quite fast without them, but that fixed it for me.

as for crashing while playing, i assume you mean a game? that could be a temp issue. a full on crash while gaming is definitely something that can cause the system to reboot. you're going to have to log the temps while it happens to find out.

Thanks for the answer. I changed ssd from the crucial one to a samsung evo and seems working normally now.

Neither freezes during game are happening from when changed boot ssd. Where can I find that option in bios?

Still doing it

Cant even enter bios because it boot so fast and then slow down extremely in the first screen of windows where i have to put the password

Update 16/06/2017 5:58p.m.
I finally went into the bios and the option is already disabled

I enabled it to "ultra fast mode" to see if it makes some differences

Ok maybe could be something wrong with ram because i see the led of my motherboard (z170x ud5 th from gigabyte) displaying the number "51" and it means something went wrong with ram

Ram specs: 16 gb ddr4 corsair CMK16GX4M2B3000C15 Vengeance LPX 3000mhz (currently running at 2133) CL 15

Hello? Any ideas?

sorry. again, im not on daily. you seem to be making really good progress diagnosing the behavior yourself. this could be a ram issue, though not a traditional one that would make you point the finger to it from the get go. so, when you have ram issues, traditionally you start by removing all the dimms(the ram chips), then trying the system with 1 dimm in at a time, and then try each dimm in each slot if you want to, to diagnose if its a bad dimm or ram slot. now, with your problem and the behavior you've been seeing, this might take awhile as you wait to see if the behavior persists. however with that code readout on your motherboard, it could be helpful in speeding that process up if it registers the error rather quickly.


i will also suggest you look at the ram settings in the bios. if you're downclocking your ram, that can cause issues. i've never had to do it myself, but my friend got ram he had to do that with when he did his last build and it caused him no end of trouble. the setting you want to look for is xmp. this allows the motherboard to decide on and set the ram to what should be the fastest safe speed it can. like autotuning instead of you having to pick all the settings. the ram you have specifically supports xmp 2.0, as should an x99 board i'd assume you have if you're using ddr4, though i dont know if the settings will specify the "2.0" part in its description.

I did a bios update and seems everything is working fine. I dont know if i should close the post because i dont know if this will be happening again
