For the past couple of months I have noticed that my computer has been running very slow and I haven't been able to play games and I can just about browse the Internet, but I can't watch YouTube videos. I used to use my computer to play game whilst browsing the Internet/watching YouTube videos and my computer would run perfectly. I have tried many things to get my PC to run faster and yesterday I even re-installed Windows 8.1, however nothing helped significantly. It wasn't until today that I realised it was my CPU that has been slowing down my PC, at least that is what I think is slowing down my PC. So, today I cleaned out my PC, replaced the thermal compound on my CPU, fitted a new case fan and tidied up the cables. However, my CPU is still running at 90-100°C, does anyone know how to fix this problem or what could be causing it?

It's not the first time I've heard of the stock coolers suddenly getting high temps. I have a feeling the plastic retention clips (hate them) become somewhat weakened over time and since there's not active way to tighten them (like screws) they may be losing pressure. Which could account for the high temps. That's wicked hot even for a loaded stress test.

Personally I'd drop the stock cooler and get a decent aftermarket cooler. Considering it's a somewhat cramped case, something like the cryorig h5 universal would do pretty well (width, not just height).

Only a degree or two less cooling than the nh-d15 for about half the price...
Do you know if any of them in particular take up a lot of resources?

Win 7: If you goto windows key then type in msconfig then go to the startup tab you can choose what to load on windows log in

If you're not sure what your stopping though I wouldn't mess with services
 


Okay, I will just leave it then. I was just wondering to see if I could make my PC any faster. Thank you for your help.
 
[/quotemsg=16290424,0,2038387]Seen as you guys are so helpful, could you tell me if all these background processes are necessary and how I can stop the unnecessary ones from automatically loading? http://imgur.com/GrsvxIG[/quotemsg]

Don't know how to stop programs from starting up when not necessary and they have no option for doing so, unless you choose to do it manually via the Task Manager every time you startup. However, I've used a program for about 10 years now that does this automatically for me so I don't have to worry about it. That is AVG PC TuneUp, formerly TuneUp Utilities. I use it for much, much more that just that.

It does, under it's Optimize tab within the program, have two buttons - one to Disable Programs and another to Disable Startup Programs.

Disable programs allows one to stop programs, such as Adobe Reader from loading at all. That doesn't stop the program from working - one just clicks on whatever ICON or short cut they have for the program and it will startup as usual but then deactivate again when closed and not needed, thereby not using any cpu resources. That component is actually called AVG Program Deactivator.

The Disable Startup Programs button pulls up the AVG StartUp Manager component. That allows one to stop parts of programs from loading up into Windows. One such program for me is my CyberLink PowerDVD 14 program that, when active uses a lot of system resources. I only need this program when I'm watching a DVD or Blu ray disc, so I have it disabled at startup. Again, once the program is closed and no longer needed, AVG PC TuneUp will return it to its disabled role. Other such software on my PC: DYMO Label printing software, Java Platform SE Auto Updater and my Samsung Magician SSD program that interferes with my War Thunder MMO game launcher when active. They are all disabled, freeing resources for better performance and game play.

Take a look here, if interested at all: http://www.avg.com/us-en/avg-pctuneup

Also, the program is very aware of the differences between a hard drive and SSD - it will only defrag HDs, not an SSD.

You might have no interest in this, but this is just a suggestion, something I've used for years now. :)





 
stopping unneeded\unwanted Start Up programs:

run Regedit. check registry - "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run". anything listed here you don't use or want starting automatically, delete.

open Task Manager. check Tab - "Startup". disable\delete items listed here you don't want\need.

open Task Scheduler. check all listings under "Task Scheduler Library". delete unwanteds.

*Windows 8: open folder - "C:\Users\*user_name*\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup". delete anything listed here you don't want\need.

*Windows 7: look in Start Menu > Programs > Startup. again delete...
 


Disconnect the internet while the machine is running. There could possibly be something you don't want running on there.

 


 
check to see what processes are consuming cpu bandwidth. if CPU bw is low, confirm the cpu case help with an ir thermometer. or very careful touch test... is it really running hot? as mentioned, use a utility to make sure core vdd is reasonable, say around 1.32 v or thereabouts.
