The system boots up the moment power and becomes unresponsive.
I recently had a trojan infection in my desktop computer that ended up with me have to reformat the harddrive, however, before I could do so, a new problem showed up. Whenever I give the system power, it boots up automatically, and will not shut down, nor restart, even if I hold the power button down. The only way to turn it off is by flipping the switch in the back. It displays nothing on the screen either, so I can't do anything with it. I tried replacing the hard drive, and that didn't help either. It currently has a blank hard drive in it, and still does the same thing, and it will run like this even if I disconnect power to both the hard drive and the CD-rom drive. Any idea how I can fix this? I can only assume it's a motherboard problem, but is there a way to make it work without having to replace the board?

Re: The system boots up the moment power and becomes...
Try resetting your BIOS.
To do this, depending on your board, there will be a small battery. Make sure the power connector is removed, and then remove the battery from the board. Wait 30 seconds, and then reinsert the battery, taking care to make sure it is in the right way round.
Try powering up your computer again, and see what happens. You will almost certainly have to reset the clock afterwards, however the computer should automatically detect the drives, allowing you to reinstall the operating system etc.
If that doesn't work, then it sounds like you have a failed motherboard.

The problem is caused due to the virus infection. Copying and pasting text is not an issue however the problem that the virus caused you is copying and pasting files. Installing a license antivirus may help you with the problem. Once the problem has been fixed you need to backup the files and reinstall the operating system because some registry or files might got corrupted due to the infection.
You cabn try to install and clean your computer using this. click here. A 30 day trail antivirus just fillout the form and it will send you a link a verification email.
If this has not been happening before,maybe you just noticed it, then you can only think of this as a result of infection on your system, it can be a virus, trojan horse, malware etc.
What you can do is to scan your system thoroughly with a good anti-virus to remove any infections,note that the anti-virus must be updated before it is used
In that case the safest way is to backup your data to a USB memory stick, reinstall Windows with a full format, install your antivirus (Avast since it has the boot scan option), update everything and scan your backup before reimporting the files.
Microsoft does not "shut down" computers. If the PC is not booting every time it is because of the viruses or the power supply. If you press the power button and nothing happens I suspect the power supply. If you see the start-up screen every time you press the power button, but the computer does not finish booting go ahead and install your legal copy of Windows and that will fix the problem. Make sure you have the drivers for your motherboard, you'll need them to install things like chipset, nic, video, and sound drivers.
Hi glamredhel, Norton has removed the virus or Trojan & if you have windows system restore turned on the virus or Trojan will return once the system has re-booted. Open windows device manager & shut off system restore. Re-boot your system & re-scan your system with Norton. In your case Norton did not give you instructions on how to remove the virus. (Norton did that for you). Once completed check windows update service for a possible update for your LAN. Asus does not have a separate LAN driver listed on Asus web site. The LAN driver is part of the chipset drivers. Remove your modem from the system & any software you installed with it. (If any). Restart your system. (If the system seems fine-good. Shut down the system & re-install your modem & any software. When completed do another windows restart. See if the modem functions (If your modem is either a cable or DSL reset it. Shut down the system. Located on the back of the cable modem or DSL modem you will find a tiny re-set button. Unplug the power cord from the modem. Take a pen & press the reset button for 10 seconds. Re-connect the power cord & boot the system. Check for internet connection. The above are just a few item you should try. Good luck glamredhel! Post your findings. Mike
NAV 2004 and below were notorious for this likely issue. NAV would go into a loop re-writing the infected code into a temp folder as part of a detection routine gone crazy. Given enough time it could fill up your hard drive with the infected code. I quit using all Norton products as a result of this. There is a fix tho, but it involves some real work on your part. So my suggestion is to TRY to put the computer into safe mode and remove Norton. Why? Because it has become the bigger of the two problems and keeping you from solving the real issue. If you have access to another computer on the internet, download Avast Home 4.7 ( www.avast.com ) and try to install this product while you are still in Safe mode on the infected computer. Get the VPS update file while you are downloading as that contains almost all the necessary updates to the main Avast program. Install the VPS updates directly after installing main program without rebooting first. That will let the updates function during the necessary scan at reboot. If for any reason you are unable to remove Norton in Safe mode, there are small routines available on the Norton website that will allow you completely remove the program as if the Un-install no longer functioned properly. These routines can sometimes be difficult to find but they are there and if necessary I can get them for you.
Whatever you do, give Avast a try, you'll be glad you did. Contact me directly if necessary at ' email@example.com ' or Yahoo Messenger ID ' hantoyo1 '
