I bought my laptop in late 2013 with the following configuration:
- Motherboard / model: NP-530U3C
- Intel(R) Core(TM) i3-3217U CPU @ 1.80GHz
- RAM: 4GB DDR3
- Hard drive: 500 GB 5400 RPM + 24GB SSD
- OS: Windows 8.1 (Was 8.0)
I was told that this should be enough for my needs (various browser tabs open - I use chrome, photoshop, dreamweaver, excel). At first it was pretty good, but overtime it has become increasingly slower and slower, and now sometimes even opening a folder or pressing the right button on a file is insanely laggy.
I checked for viruses several months ago and didn't found anything. I also went through my enabled processes, msconfig, and startup and disabled everything unnecessary (Including antivirus, Apple processes, etc.), and yet still slow.
I've attached a screenshot of my current pc status with only about 10 chrome tabs open and photoshop opened with one file.
Is the 4GB of RAM the main cause? If so, is it possible to add more memory to my specific model? How much and which type is recommended? If it's only a low RAM problem, why in its first months of use did the computer do much better?
1Does the HDD report as being healthy? Unexplained latency between I/O requests is often explain by a HDD that is in the process of failing. You are also using a large majority of your memory. It could also be a memory leaked cause by a driver, if that's the case, boot into a minimal boot configuration to see if it still happens. If it doesn't then load each additional drive one by one until it does happen. Once you do that you have determined the problem device driver. – Ramhound – 2015-04-14T13:57:00.063
I've booted with minimal and it was much faster, but then I simply booted again as usual and it's still pretty fast, with about 60-70% RAM in use (even with few more open apps), as opposed to the situation in the screenshot. it seems like the 89% used RAM situation usually evolves after a few hours of use, I don't know what is triggering it exactly. What could it be? and how to check HDD health? – rockyraw – 2015-04-14T15:34:02.993
I listed several possible reasons. – Ramhound – 2015-04-14T15:39:36.970
is there a way though to recognize in real time which driver it could be? as I mentioned, sometimes the laptop is doing ok, even though, as far as I know, all drivers are running. Could it be that a driver that is usually dormant is the one that is causing the memory leak? If so how can I monitor such driver? – rockyraw – 2015-04-14T15:43:59.313
I told you how to determine which driver. The real-time method requires additional technical skills. The method I describe if done right is guaranteed to find the driver, if its a driver, you have to eliminate the other option first though. – Ramhound – 2015-04-14T15:56:31.040
perhaps there's some software I can download that monitors in real time? about your suggestion - under the msconfig boot menu, I don't see an option to manually select individual drivers, can you elaborate how to to that? – rockyraw – 2015-04-14T16:09:43.347
Autoruns, a utility, will let you select which drivers will be loaded. – Ramhound – 2015-04-14T16:27:33.627
the 1.2GB non paged pool usage is too high. Diag it with poolmon: http://superuser.com/a/674725/174557
