Hey everyone!
I got this lenovo y50-70 laptop about 1-1,5 years ago. Now I am facing a few serious problems with it.
Problem 1: The cpu is acting exactly the opposite of how it should be. While browsing or just doing whatever not highly consuming process, the CPU is finely working around 3.5 Ghz, operation voltage is at 1.068V. However, as soon as I start building, or do anything that would need any more power, suddenly I see that my cores drop to 2.6Ghz and voltage is as low as 0.78V.
This made me curious, and started testing with prime95, cpuz, Intel Xtreme tuning utility and so on. Each of them showed the exact same result, that as soon as the CPU should perform, it drops down to 2.6Ghz, while the temps are more than fine. None of the cores are above 65 degrees Celsius! This is not a simply bothering problem, but a serious one also. Software and tools used to track and monitor information regarding system health: HWInfo64, Intel XTU, Aida64 and CPU-Z.
Problem 2: The laptop is slow, like way too slow. Opening apps, files, documents, whatever takes up to minutes some times. While I had windows 8.1 on the HDD I had response times between 10K and 15K ms and insanely low write and read speeds. I gave it a full clean reinstall to windows 10 and now my response times are fine. I tested with HD Tach very recently. See the attached results. I went on and ran memtest over night as well, in the morning it showed that it found 0 errors. Since the windows 10 reinstall however I am facing daily BSODs, like between 2 to 6 in an 8 hour period. The error message on the BSOD is "page fault in nonpaged area". I looked around and found that issue could be in the page file setup, so following the recommended setup I ended up having a few less BSODs, like 2 to 4. However the problem still exists and is rather bothersome.
I would like to find a solution for both of the problems, and preferably as soon as possible due to the limitations I am facing due to the poor overall performance of the laptop.
If you can add any thoughts, ideas or help me in any way, please do so! :)
