Sounds like your driver possibly became corrupted. Go to device manager and uninstall the driver and reinstall. If you have already done that, then I suggest you run system restore to take it back to an earlier point to see if that fixes it. Try running Avast anti-virus to see if the driver is infected.
Try pressing F8 while the laptop is booting and select "safe mode". If it boots fine in safe mode, it might be either driver issue or the laptop's videocard giving up. The driver issue is corrected by installing the right drivers, you can ensure if the problem is on the hardware side by setting it to boot in 640*480*256 (or lowest possible resolution) and see if it boots. Also, try pressing F8 during boot and select the option to log the boot process. The log file might then tell you what causes the stop/hang.
There are a few different numbers that tells networks, the
Internet, other computers and so on who you are.
These numbers can include the internet protocol address (IP
address), which can be four numbers from 0 to 255 in version 4, or even more in
the newer version 6.
However, of all of these numbers, there is one number that
identifies your computer and your hardware uniquely, and that is the Media
Access Control address, or MAC address.
Open up the run dialog.
This can be done in two ways, either "windows key +
r", or go to the start menu and click on "Run".
Type "cmd" to bring up the command prompt.
Type "ipconfig /all".
Record your MAC Address for each device.
There will be one or more devices listed depending upon the
number of connections you have, such as Ethernet port, modem port, or wireless
port.
Each of these will have a field listed as Physical Address,
consisting of six, two number of letter segments.
For example: 12-34-56-78-9A-BC
Linux users
Open up a console window.
This can be accomplished in many ways depending on your
distribution.
Type ifconfig -a.
This is analogous to the above ipconfig /all.
Record your MAC Address for each device.
Machintosh owners
Open System Preferences and select "Network".
Choose your interface (such as ethernet or wireless) in the
"Show" box.
Find the MAC address. For the Ethernet device, it will be
under the Ethernet tab listed as Ethernet ID. For the wireless, it will be
under the Airport tab as Airport ID.
Record your MAC Address for each device.
You can download the driver on there website support find your model and download. If there is no support driver in there site download the driver navigator. if you cannot find i can share you my copy.
Go to the Online support of acer. you can download the driver of your laptop model. And if you can't still find the driver of your eye crestal webcam use the driver navigator software.
open the battery of the laptop from the back of your laptop.... now remove it from the plug also...... now press and hold the power button for 60 seconds.... now put in your battery and plug it in ... and try to open the laptop.... hope it works.... else you have to restart your laptop and as soon as you press the power button press F8 key repetedly... then go to safe mode ... then go to all programs.... system tools ----system restore an go though the steps ... and restore it...
See the PrtSq/SysRq key to the right of the F12 key?Hold the Fn key down, and press that. (PrtSq = Print Screen)For additional questions please post in a Comment.Regards,joecoolvette
You can try to reset the password in Vista with command prompt.1. Press F8 to enter Advanced Boot Options just before the Windows loading screen appears.2. Choose Safe Mode with Command Prompt.3. Log in with an administrator account when you can see the log on screen.4. Type net user in the command prompt and then hit Enter. All the Windows account user names will be listed for you.5. Type net user Helen 123 and hit Enter.
'Helen' is your locked Windows account user name. And '123' is the new password you want to reset for the account.If you cannot enter the safe mode, I'm afraid you have to create a password reset disk with a CD or USB drive as follows. Otherwise, reinstallation will be your only choice.
Step 1: Download and install Windows Password Reset Deluxe from http://www.windowspasswordreset.net in any computer from its official siteStep 2: Use CD/DVD/USB drive to create a password disk via the program.Step 3: Boot your locked computer from CD/DVD or USBStep 4: Reset Windows password with the burned CD/DVD or USB flash drive.
First - re-seat the harddisk and reboot the computer. If the computer does not boot up then reboot andgo into the BIOS configuration to see if the BIOS detects the hard drive. If itdoesn't detect the hard drive then it could be faulty.Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.
You have a hard drive problem. The bios is going through the boot order, looking
for a bootable device, it is not recognizing the hard drive as bootable
so it moves on to pxe....a network boot. Bottom line....make sure the
hard drive is all plugged in. Find out the make....and go to the
manufacturer's website....download the ISO to make a bootable diagnostic
cd.....and do a quick test, then a long test of the hard drive. If it
passes, you make have to re-install the operating system. Sometimes you
need to load sata drivers to recognize the disk, but not usually with
most newer stuff (unless it asks for the driver during the install,
won't see any hard drive). So I would find out if the hard drive is any
good, or not. If you cannot find the diagnostic you could try seatools
which works on most hard drives, but its best to use the one for that
hard drive. Here's the link for seatools:http://www.seagate.com/support/downloads/seatools/?locale=en-US&name=SeaTools&vgnextoid=720bd20cacdec010VgnVCM100000dd04090aRCRD
I suggest check out the AC adapter first. 1) When plugged into power, and plugged into the laptop, gently wiggle the cable from the AC adapter TO laptop.Any change?Do the same on the power cord TO AC adapter.NO?Go on.2) The port on the laptop that the plug from the AC adapter plugs into, is the DC Power Jack.If we are discussing an Acer Aspire 5738Z Notebook PC, the DC Power Jack resembles this one, (Not installed),http://www.batterysupport.com/acer-aspire-5738-jack-p-302046.html(When I note the DC Power Jack, it is this link I will be referring to )As you can see there is a Center Pin. All power removed from the laptop, use a small wooden, or plastic object, and see if this pin moves around.ANY perceptible movement means a bad DC Power Jack.DC Power Jack checks out it's back to the AC adapter.Wanted to perform the easy diagnosis first.This will require a multimeter. An economical, yet fine for this test multimeter, can be purchased for as little as $8 to $12.Available in a multitude of stores. An auto parts store is but one example.Analog or digital is fine.http://www.youtube.com/watch?v=bF3OyQ3HwfU(Analog is fine. Some of us still like 'em)DC Voltage is what you are going to check. Black probe lead (Negative) goes in the Common port on the multimeter. (COM)Red probe lead (Positive) goes in the Voltage port on the multimeter. (V)If the multimeter just has symbols around the Function Knob, set it to the dotted line over a solid line, symbol.The plug on the end of the AC adapter, that plugs into the laptop, has a center hole, and a cylindrical metal shield surrounding it.The Center Hole of the plug is where the red Positive lead, of the multimeter goes.The outside cylindrical metal shell is where the black Negative lead of the multimeter goes.Hold the AC adapter plug in one hand, and at the same time hold the red Positive multimeter probe in the center hole.With the other hand touch the black Negative lead of the multimeter, to the cylindrical metal shield on the outside of the plug.You should read 19 Volts (DC), or VERY close to it,http://www.cellularfactory.com/laptop/ACER/3/305268/I believe the AC adapter is the problem. Post back in a Comment as to your findings.Regards,joecoolvette
You are right! the inverter is the likely problem, unfortuneately unless you have another screen there is no reliable way of testing, the inverter puts out at least 1000 volts and don't attempt to check with a meter it will probably get damaged.
