Hi, I have a problem. The computer worked fine but I tried pluging in a 2nd harddrive and that didn't work. So I just took it out and left everything as it was before and turned it on. It asked me to start windows in a safe mode and I did. I did a system restore and when it finished the monitor went Black and nothing was happening. Now every time I turn it on it makes 3 beeping noises and sounds like its running but the monitor is in a stand by mode and nothing is happening after that. Please help, its very important And also the computer I used to post this with also has a slight problem. When I turn it off for about an hour and turn it on its pretty quiet for about 10 minutes and then it becomes loud as hell. I think its the cooling fan, but none of my other PCs ever were this loud. Is it possible to make it quiter?
