System Slowing down after medium-long session

[Pauuuuulix]

Hello community,
time to time happens that my whole windows( and everything else that could) slows down and any kind of tasks are very painful to complete. Even writing becomes very laggy.
Usually I'm in the middle of gaming and have a lot of apps opened.I try finishing what's unfinfished and close everything(usually at this step I restart my computer). By checking task manager I can see memory used at 99%. Last time I was curios how slow can everything finally turn(since it slowed even more down with time) and after about 15 mins cpu usage hopped to 100%. Then both my screens turned black(only mouse cursor didn't disappear) and I had to hard shut down my computer by the physical button. So far the only solution to this has been restarting the computer. Any solutions are welcome!

mate honestly im at a loss. theres defiantly something causing this issue.
all i can recommend is you try scanning with different anti malware apps.
try the emsi soft emergancy rescue kit and spybot search and destroy.
1s scanned run sfc /scannow from the cmd prompt to repair any broken windows files..
if that doesnt fix it. then i recommend you save your important files to another drive and reinstall windows from a cold start.

*cold start. means turn the pc off for 30seconds to 1 minute... (wait till the motherboard led's go out).
boot the machine into bios. change the drive order to dvd rom/usb boot drive
insert the install media and save/quit bios.
the machine should boot immediately off the drive you just selected.

do it from a cold start to make sure there is nothing memory resident and hidden at the clean boot.

i had a think on this. and if you havent gone ahead and wiped the machine.
try using msconfig and turn on basic boot. run the machine and see if the same thing happens.
also clear out the applications caches with ccleaner. ive seen systems with 20+ gigs of cached web data and the sheer amount of small files on his hdd, was bogging the whole system down to a crawl.

while you have ccleaner open check the tools/startup and check all the tabs for stuff you might not want running. often little bits of junk can hide here.

Emsisoft emergancy kit found nothing, I am pretty sure now it's a windows's own fish, is that possible?

No I haven't wiped the machine yet, but I should plan it on some weekend.
In Ccleaner startup mager i only managed to uncheck 2-3 boxes of some automatic-updates. Since I clean with ccleaner quite regularly I only managed to clean 661 MB.
About the basic boot, I already tried it earlier on your recommendation and it did not help.
So if I am planning to re-install te OS, maybe You could recommend me some alternative free anti-virus software. Bitdefender is not quite for me with it's randomly popping up sometimes and no decent control center besides the same pop-up thing.
And to prevent the same issue in future, should I avoid installing somekind of software or things? Any advice is welcome.
EDIT: Another question, should I burn the iso file on the disc with slower speed (some files may get corrupted?) because for example last time had a problem with installing OS i reburned the iso file with slower speed and everything was okay. Is slower burn speed better for cleaner OS installer?
EDIT NR2( 😀 ): I found some people with the similar problem and they had most of the ram non-paged and solutions to this were driver updates. Next time I ran into the same slowing issue I will check about non-paged ram. BUT since I now monitor my ram usage after every couple of minutes I haven't noticed a significant ram usage rising (idle was 1.6 gigs at start). I'll update my gpu drivers and try some gaming later and try not to shut down my computer to see how it holds on. (thumbs up, it may be fixed, atleast i hope so)

EDIT NR3: I've heard from some people Alt+Tabbing may during games may cause freezing the sytem and is overall not recommended, since I do it a lot, especially during gaming may this have something to do with my issue?

if sfc /scannow ails to repair then repair install in your next option.

alt tabbing will depend on the software. in some rare cases alt-tabbing will cause the app to crash but its less likely to cause windows too.

as for burning disks, if its important to get the data right. burn at a slow speed. things like movies can be burned at higher speeds. but program files... slow as possible which is normally x4 for me.

 

[Pauuuuulix]

Okay results are the same, after some time of usage idle was at 61%. I personally prefer the whole OS reinstall because it wipes everything off and I'll have a clean start. I'll burn the disc at 1x just to be sure.
But about the anti-virus software, do You know anything good besides bitdefender? Is Avast worth it?

 

[HEXiT]

personally i use avira free paired with malware bytes. they work for me and have little in the way of popups 1s you set them up.
8 years no with problems that i didnt create myself.

theres also kaspersky. its well rated at number 2 for the last few quarters. but it too can feel like its bugging you after a new install.
but 1s you go through the av learning period its pretty straight forward.

Thank you for your help. I'll try the same combo to follow the professionals. 😀
But before os reinstall i'll first search the web about non-paged ram. At the moment with just google chrome opened the usage is 4.9/7.8gigs and 3.0gigs of that is non-paged. Cached is 2.8 gigs, which one of them should be smaller?

 

[HEXiT]

paged ram numbers should be relatively small compared to actual ram usage. even with chrome and opera open my system is using 2.6 gigs with opera open by itself 2.4 gigs. (but thats with no tabs open. )

have you removed all the extensions you have in chrome?

 

[Pauuuuulix]

I only have adblock, I find browsing without it quite frustrating.

 

[HEXiT]

when you ran sfc /scannow did you run it with elevated privs? (right click run as admin?) if not do so...

 

[Pauuuuulix]

Yes I did run as admin, otherwise I wouldn't have been able to use that command at all.

 

[HEXiT]

well in that case mate im outta ideas. unless its a root kit i cant think of anything else that might cause this...
me , if i was in your position, now?... i would just try a repair install or fresh install.

 

[Pauuuuulix]

I'll go for the fresh install, cleanes computer clear of junk.
PS: I earlier already scanned for rootkits with malwarebytes.

 

[Pauuuuulix]

Using computer after fresh install feels so good and clean. Thank You again for Your support! Currently with 6-7 programs opened RAM is only at 44%!
I also followed your option and installed avira and malwarebytes combo. I really admire the open database of viruses/malware Avira has.
I wish I could thank You better than that. You enlarged my knowledge and in the end.... solved the problem. 😀 No matter how troublesome it was.

Thank You!

your welcome. im just sorry we couldnt get to the root of the problem...
