As the title says after my computer has been on 24/48 hours it randomly becomes extremely sluggish or even unresponsive when opening/closing programs and has to be manually rebooted via the power button as doing a regular shut it hangs up at the computer shutting down splash before the video card shuts down but everything else remains on. The slowdowns mostly seem to happen after the computers been left idle from what could just be 10 minutes or overnight, when it happens some programs will continue to work fine (ex. TEW 2010 game & Notepad), some will take a lot longer than usually to open or close (ex. Firefox & Winamp), while others will not open or close at all (ex firefox, vuze, winamp, explore). The windows task manager doesn't show a spike in cpu or memory usage. Once i reboot it via the power button everything mostly goes back to normal with only slight lag here and there.
Somethings i've tried to fix it are not overclocking the gpu or cpu, reinstalling windows 7 several times (inculding after formatting the SSD), different video card drivers, different audio drivers, anti virus programs (MSE, Malwarebytes & various online scanners), different bios versions and different power outlets. I'm honestly at loss as to what to try next software wise, which has brought me to believe it may be something hardware related. Any suggestions or advice would be greatly appreciated.
It also should be noted that i leave my pc running all the time (and have done so with many pc's for years) only rebooting it a few times a week when i have to for updates or newly installed programs and when it seems a little slow.
