This issue is very bizarre, I don't know how to properly describe it other than something amiss in Windows itself with my primary HDD. So, I use browsers a lot, and I'm on them for a decent portion of the day, but something has been very weird going on and either the OS is using too much virtual memory or something more serious is going on. I notice that as time goes on, I seem to "lose" 1 GB every so often, and after a while, it seems to reset back to normal, I tried to Google this, nothing definitive shows in the results. Some say it's a memory leak, others say it's too much page file memory being configured or a virus, malware, etc. I have looked for viruses and malware and haven't found any with any kind of scanner. Only thing I can think of running is CCleaner, and clearing out the Temp files, but see that makes me somewhat paranoid because I'm afraid it will somehow affect the Registry (despite that being a separate option to scan and clean in the program), maybe that's why, a lot of accumulated temp files, I don't know. Is it safe to let CCleaner scan and remove whatever it finds in the Temp folder or should I be wary when I scan and remove that? I noticed entries in the temp folder that seem an awful lot like temporary registry keys/entries, I don't know, but I didn't scan the registry, just temp files. I don't know what's going on, why the HDD "loses" more and more GB over time, and then resets back to the amount of X GB, this is getting really annoying and I fear the worst. Any advice you guys have will be appreciated, thank you.
