Not sure, but try loading Safe Mode by pressing F8 during boot and lowering screen resolution. In Safe Mode you can even run System Restore. It load to a previous date that you choose.
The bios has to be usb boot-able you will know that by going into the bios and looking at the boot-able device array and it will show a usb choice. The usb flash drive has to be formatted as a bootable device and thats a pain in the @@@.

Try another monitor. If that works, download the latest drivers for your OS here... http://us.acer.com/ac/en/US/content/drivers
If the old monitor still doesn't work, here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
RJ45 cables have a lock lever, which you need to press before pulling the plug out of the socket. locate the lever, press it towards the socket (sometimes you need a screwdriver or similar), then you can pull the plug out.
You can usually install them on the back of the computer case. If that space is not available then you can always drill holes on the side panel immediately above the motherboard and mount the fan there.
Restart your computer during the boot process you will a certain key to press to enter set up usually the Delete or F2 key this will vary depending on your operating system and computer Press and hold that key during the boot up process to enter BIOS using the arrow keys navigate to Advanced Bios features press enter you will see the boot order Change the first boot device to your hard drive. The BIOS is AMI. Under ADVANCED SETUP: The options listed for 1st,2nd ,3rd Boot device include: IDE-0 means Pri master ? IDE-1 means Pri slave ? IDE-2 means Sec master ? IDE-3 means Sec slave ? If you are unsure or have made mistakes you can load optimised or failsafe defaults this will automatically set the boot order Hope this helps.

A bad capacitor can cause a variety of computer problems, but if you can identify the faulty capacitor you may be able to replace it and save your computer. Capacitor Capacitors, sometimes also called condensers, are used to store energy in an electric field. In the context of computing, capacitors are used to block the direct current being circulated around the motherboard. A typical capacitor should last up to 15 years, but some computer manufacturers use substandard capacitors resulting in shorter lifetimes. Computer Problems b> When a capacitor has gone bad on a computer you may experience a large range of problems. The computer may have trouble booting up, or it may shut down without notice after running for only a short period of time. The most common problems associated with faulty capacitors are that they cause unexpected computer crashes and general reliability issues ranging from read/write issues to distorted screen images. b> Identifying a Bad Capacitor b> To identify a bad capacitor you will need to open your computer case and locate the capacitors on your motherboard. A bad capacitor may exhibit swelling at the top or the base of the capacitor or it may sit at an awkward angle with the motherboard, so compare the various capacitors in your computer in terms of and placement. Additionally, a bad capacitor may have a funny smell or it may have a brownish residue leaking from the top or the base. b> Prevention b> Manufacturers claim that capacitors may go bad because a computer is not receiving enough power from a power supply, because of an overclocked processor or because a computer is operating in an environment with too much heat or humidity. However, some capacitors prematurely fail due to faulty work on the part of the manufacturer. If you have a bad capacitor be sure to do research as to the lifespan of other products made by your manufacturer.

First, new hard drive must show up in BIOS. Verify. Then try setting CD\DVD (optical drive) as 1st boot option. You should get "Press any key..." on the screen to set up Windows. There is a bigger problem if you can't get to this point.
Put a Phenom 1095 6 core in mine and it worked Upgraded the PS just in case. Now seem to have a BIOS problem though probably unrelated. If you google acer m3400 data sheet you can find the specs.
Yes you can add the lightscribe drive to your system as long as you have an open pay (slot) to hold it. If you have a desktop tower, then most likely you have a slot available either right under or above the current dvd/cd drive. Just make sure your lightscribe drive has the same interface (SATA or IDE) as your current drive or you might need some cable adapters to make it work.If your system uses IDE (little metal prongs or pins where the cable plugs into the back of the dvd/cd drive) then you want to set the jumper pin on the back of the dvd drive to CS for cable select. If there is a cable ribbon going to the current drive it will have another connection open that you can use for the new drive. Normally the cable ribbon will allow you to piggy back the two drives.SATA is the latest technology so if your current drive is SATA, and your lightscribe is SATA then look at the two cables that go into the dvd drive already installed. There might be another set that is not being used that you can hook to the lightscribe drive. If so, hook the set to the back of the drive and into the slots on the motherboard.
please check the memory timing settings. if your mixing up ram they may not have the same memory timings and require you to go either higher or to the supported settings that either memory can use. for example if corsair runs at 8-8-8-14 and kingston runs at 10-10-10-16 then you will need to bump the settings to 10-10-10-16 since the computer is trying to set the timings for kingston to 8-8-8-14 which it does not support.
Hi,When you start the computer for the first time, it will ask you to setup the Operating System. You can follow the onscreen instruction.If you are referring to attach any device on the computer, then you have to go to the manual that you received with the box, in case of Acer, the manual should a big chart sheet.Please revert for any clarification.Thanks and regards,Jitha.G.J
Hi,I understand the inconvenience. It may happen due to
automatic updates. Since, it is happening from yesterday, I would
recommend to run a system restore to the previous date. To do so:1. Click Start Menu> All Programs> System Tools> System restore2. Select a previous date on which the computer was workingNote: If any change were made to the computer, it will be erased.Please revert back to me for any clarification.Thanks and regards,Jitha.G.J
Hi,Please let me know the 3 issues you are facing. If it is not related to hardware repair then let me try to resolve them.If the computer need repair then you may need to contact Acer Technical Support @ 1 800 816 2237Thanks and regards,Jitha
