A while ago I noticed that my C: was nearly full and decided to make some room on it. I removed some useless stuff and got 4 gigabytes of free space. After that I started playing wow and noticed this MASSIVE lag, I immediately logged out and saw that there was only 100mt free space on my C-drive. I cant find the "mystery" files from anywhere. I reseted the page file, disabled system restore and still the "extra" 4gb didn't get removed. Now I can barely play WoW cause of this massive lag (fps going down to 4 if i have more than 5 people around me, I got GF8800 GTS and E6750). And btw, I checked the size of all the folders on my c drive (including invisible ones) and they are 10 GBs big added together but when I check it from properties, it says I have 19GBs on my c drive. Is there any ways to solve this problem, or is it just better to format c?
My OS is Windows XP professional edition and I also cleared the Temp folders. (didn't find the way to edit my previous message)
Your best bet is to do a scandisk on all your partitions (make sure the box to fix errors is checked). It would be under "my computer"/c: drive/properties/tools/error checking/scandisk When it does a scandisk on the system drive it will have to reboot, during bootup it will get the blue scandisk screen. If your c: drive is large it can take 1/2 hour or longer. The symptoms you describe (not listing the correct size of hard drive and slowdown) is a sign of file corruption. A scandisk can usually fix this.
