What is my harddrive doing now ???

Try looking at your processes. If there is any programs or processes running without your permission, then there is a possibility it's a virus.

I would call the company you recive your connection from maybe they do some kind of mantaince work the same time every night or day if so I would just shut the computer down at the time and I dont know if you have CCleaner but it is a good free program that is good at checking for reg.errors if you have any I have alot of free programs that help keep my computer free of gunk lol lol

My computer does the very same thing to me also. I have dialup. I never turn my computer off when I am not online. I have to restart my computer to get it working right again.

The blinking of your hard disk may be due to the fact that even when you do not do anything, the computer actually works. There are several processes that run in the background and the user is unaware of them. It may be due to this reason that your hard disk indicator blinks even when you dont do anything.. Now about your computer being slow, there may be several reasons for that like your compu may be over populated with installed programs. Viral attack can also be not denied.

Possibly it is running a self check or a virus scan?

Your harddrive is doing some hard work, and you should start worrying, but not panickina. It happens about the same time every night, and you do not have any scheduled program such as an anti virus running? Let us start with the wifi. If someone piggy back on your Internet connection it can slow down your Internet access but NOT your computer. I know because I use wifi at home. At the beginning I did not mind someone hopping online to check his email. Then one night two of his friends joined in and used an accelerator to download videos. This bogged down the bandwidth and slowed my connected. There were others who did the same after that so I had it firewalled. End of one problem. By the sound of it someone took over your computer. There is a very big possibility that your computer has been compromised. Sometimes this can be detected from the change in IP address and/or the time shown on the clock. Steps which may need to be taken, not necessarily in order: 1) Set firewall for your router. 2) Set password for your router. Use WPA. It is stronger than WEP. 3) Scan for viruses and other malware. all the best, rosdimy

I think you got schedule disk defragmentation or something virus scanner? ... If it's running hard, check if it makes any wierd noises if it does then you have to change your hard drive..

It could be your anti virus doing a scheduled scan if you have that set up. Mine will do that, but I can still do other things, just slows things down until it is done. I haven't a clue about Wifi - so can't help there. but mine takes about 5 minutes to come up - just to the desk top - when I turn it on. Don't understand that, I have the minimum on there - I am a novice and I dont' download tons of things so it just doesnt' make sense for it to take so long to start up. I have closed things on the start menu that I don't use and that didn't speed it up much. So.. I will follow this discussion and maybe we can both learn something! I hope!

It may be an effect of sharing the computer but I would have it checked out more thoroughly, it may be something else, I honestly don't know that much about computers.. I hope you can get it fixed, that is irritating for it to be so slow..

If your connected to the internet it will do that as well. Its sending and receiving packets or information even when your not doing anything. My computer does it to I only figured it out when I was on my wifi connection and it showed me what was happening while my computer was connected to the internet.

some virus would have attacked or there is some problem with ur ram or else contact the service centre fine happy mylotting

Your are using really good anti virus so no chances of virus.. i guess u need to reinstall your operating system.. internet connection has got nothing to do with your systems problems so just reinstall your operating system and check whether the problem is fixed or not..
