Cpu Usage goes to 100% randomly [Help Request]

post #1 of 5
Thread Starter 
Hey guys,

I have a problem with my processor and It really gets me tired. First of all my current setup is Q8400 running at 2.72, 2x 4 gigs Kingston 1333 mhz ddr3 rams (8 total) and AMD HD 7850 OC (2 GB Gddr5 256 Bit) graphics card. Motherbard is G41M-P43 Combo. Well here is the deal. When i try to play a game it's all smooth, no lagg, high FPS but after a while everything goes wrong CPU usage goes up to 100% and laggs everything is freezing even tho total percentage of proccesses not above 80, but in performance tab it is 100%. I don't know what's going on. For those who are going to say your CPU is bottlenecking because of your GPU, I should say that this problem recently emerged and I was able play Crysis 2 All maxed at ultra (with hd texture pack and Dx11 patch) with the same system without any problems. But now it cpu goes to 100% after a while of smooth playing with high fps. I don't know what's wrong, It's killing me. I scanned my complete system with Malwarebytes Anti-Malware and nothing found.This happens in other games aswell such as Crysis 3 at medium setting, goes all silky smooth for a while then cpu goes nutz. Anyone have an idea why this happens?
Thank you in advance.

post #3 of 5
did you look in task manager to see whats happening? is you game using the cpu up?

ideas

your ram is swapping to your pagefile
windows indexing is kicking in
windows update is kicking in
your ram or cpu is failing but not crashing system (not likely)
you are infected with something

ill edit if I think of anything else.

I put my rams to test. I have 8 gigs total but when the usage of rams hits 5 gb, cpu usage also goes to 100% freezing my computer. I think there it is something about rams or cpu. What do you think?

what OS u using? and what HDD/SSD?

im not sure but if you experience problems every time you ram usage reaches a certain level then its possible you are running out of ram. my guess is that your cpu isn't keeping up with the prefetching on your ram. once there is no free space left on the ram its swapping with the pagefile. I don't really understand it myself, but I think that's how it works.

so if your cpu isn't strong enough, it may be attempting to do some pagefile swapping or other background process, which is taking priority from your game, and causing a delay.

its also possible that you are experiencing this problem as a result of a memory leak which has recently developed in some software you already use. this can happen when u update to new versions of software. if you find that your memory usage slowly builds until this problem happens, something has a memory leak. a lot of software has memory leaks. again once you reach your max usable memory your system will slow right down.

in this case im not sure since you technically shouldn't experience a lot of slowing down until you are at about 6.5GB memory usage.
