I am having a very strange problem with my computer. My computer sometimes boots up very slowly, and hangs for long periods of time. Then it works fine, then it is slow, then it works fine... When it is slow it can take 15 mins or more to boot up. I tried booting in safe mode, but I just keep restarting before the drivers are loaded. When I boot normally, everything seems to work but, very slowly. The programs load and run if you wait long enough. While I am online, Firefox will report that it is not responding and then it will finally catch up and open the pages.
When it is running normally it seems fine. I have tried scanning for viruses and malware, but I have not been able to find anything. This is kinda driving me nuts because I know my way around the computer and I can't seem to find what is causing it to come to a stand still.
Any help would be greatly appreciated. Thanks in advance.
