I have an acer 4504Lmi. It wouldn't start, went through steps, ordered a motherboard last night. I have one concern however. I have read in a few places that a virus can damage your motherboard. Is this true? I don't want to replace the motherboard and put my hard drive in and the same thing happens. Can you check somehow? BTW I had Norton System Works on my computer and it did find some virus's before the macing went down. I took care of the ones it found. Any help would be appreciated. Thanks

Short answer up front: ordinary file-based viruses almost never "physically" damage a motherboard. However there are rare, documented firmware/BIOS or UEFI infections that can persist across OS changes, so the risk is not zero. The real, practical issues here are data loss, persistent infections on the hard drive, and Windows not booting after a board swap. That ties into points made by and but adds a safe, step-by-step way forward.

Before you fit the new motherboard, do this:

  1. Back up user data to another drive (not just copy — make a full disk image if possible).
  2. Remove the drive and connect it to a working PC (USB enclosure or SATA secondary). Run up-to-date offline scans (Malwarebytes, multiple engines or a rescue disk) and an anti-rootkit tool.
  3. Check SMART and run the drive maker's diagnostic tool to rule out hardware failure.
  4. Collect Windows product key, device driver installers, and the OS install/repair media.
  5. If you want to avoid a clean install, prepare the Windows install by uninstalling chipset-specific drivers or using Sysprep to generalize the install. Still expect driver and activation issues with a different chipset.

After the swap: try to boot. If Windows starts, install the new chipset drivers and watch for instability. If it fails, boot Windows Recovery and run Startup Repair, or attach the drive to another PC and run chkdsk and offline antiviruses. If problems persist, a clean OS reinstall is the safest route.

Final cautions: Norton detecting and removing items does not guarantee no remnants. Firmware infections are rare but real; if you suspect them, reflash the BIOS with an official Acer image or have a shop do it. The single best protections here are a full backup and a clean offline scan before you put the drive into the replacement board.

As far as I have ever known they cannot damage a mobo unless there are some code maniacs out there that can make the platters jump out of the case and onto the board:lol: , but some can however damage your hard drive in one sense by affecting various aspects of your OS and sometimes the MBR.

Some preventative maintenance is always a good idea though, run virus scans and update your definitions atleast once a week. Defragmentation is also a good habit to get into usually at bare minimum once every one-two months (depending on how much you download/delete/move/etc.)

You have two problems going into replacing your motherboard, first is the possibility that you have infections on the hdd, and second is that you are going to have a potential big problem installing the new motherboard with the old hdd.

If you have infections they will be on the hard drive, if you are going to be installing this with another motherboard than what you are already using (this means the same chip set) it may be to you advantage to wipe the hdd and reinstall the OS. This will take care of two problems at the same time, it will get rid of the infections, and problem of installing a hdd with a new motherboard with a different chip set. The hdd has recognized the chip set and drivers from the old motherboard, and when you try to install it to another motherboard it confuses the heck out of it. Some times the hdd will recover, other times it will not. For the record...mine didn't survive.
