Need help with PC stability
Few months ago i decided to change most of pc components, except Power source and GPU. Configuration is Gigabyte x79-up4, i7 3820, 8gb G Skill ripjaws x 2133, Saphire 5850 1gb, 120 gb Kingston Hyperx ssd runing windows 7 64bit, 2 TB hdd for installed games and movies.
Pc was runing smooth till 1 week ago when it got stuck at logging off screen for 2 nights, and i had to force shut down it from Button. After that i started to notice some frame drops while watching movies, something similar to playing movies from a cd that is damaged. Image stops then it plays again fast then normal. Like a bottleneck of data. It does that every few minutes, and i think that games work a bit slower too in performance. I did a scandisk test for both hdds, the one from windows, that runs in ms-dos. No bad sectors were found.
I can't figure out what's the problem, so my main question is, are there any pc monitor programs ? Something that could check performance all the time with graphics or something like that ? for cpu, ram, gpu, hdds, ... ?? Or i should look for something to test each of them one by one ? and see if it gets errors or not ?
