Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm

One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error even something as small as a faulty electrical or fan lead can cause you problems

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat Thermal compound is a sticky paste that is placed directly onto the CPU. Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink. hope this helps

you could run the chkdsk disk utility

click start run type cmd then type chkdsk/r/f which will scan for and attempt to repair any bad sectors and automatically fix any corrupt files on your hard drive

or

click start control panel administrative tools computer management ,disk management right click on your drive select properties click tools you should see click check now click start two boxes

automatically fix files and scan for and attempt recovery of bad sectors place then a tick in both boxes then select check now,start should schedule this task when restart

have no input while the chkdsk utility is in progress any input may further damage your computers operating system and hard drive

hope this helps

write your problem in details

I would suggest this generic Power On switch,

1) http://www.directron.com/atxswitch.html,

and the Red, and Black twisted pair of wires go to the Power On switch.

Your statement of ,"....don't know which of the colored pairs of wires go.....", leads me to believe you may have all of the Front Panel wires disconnected.

How about information as to where ALL the Front Panel wires go?
(Provided I have correctly interpreted your statement)

Back in the time that the eMachines T2542 was made, TriGem was the motherboard manufacturer.

The Model Name of the motherboard is Imperial, and the Model Number of the motherboard, could have been one of four variations offered.

Model Name: Imperial
Model numbers could be G, GL, GV, or GLVE
(Imperial G, Imperial GL, Imperial GV, or Imperial GLVE)

ALL four variations used the same Front Panel header.
(The connector on the motherboard the Front Panel wires connect to, is named the Front Panel header)

I would like you to view this page,

http://www.e4allupgraders.info/dir1/ecase/support/front_panel_header_support.shtml

Scroll down to the heading -
Trigem Imperial Front Panel Header Pinout.

A) Pins 1, 2, and 3 are for the Power On LED light.

B) Pins 5 and 6 are for the HarDDrive activity LED light.
(Pin 4 is not used. NC. No Connection)

C) Pins 7 and 8 are for the Power On switch

D) I wouldn't connect any wires to Pins 9 and 10, nor Pins 11 and 12

E) Pins 14 and 15 are for the Reset switch. (The button you press to restart your computer.
If the T2542 doesn't have a Reset switch, don't worry about it. There are many other ways to restart your computer)

F) Pins 17 18, and 20 are for an internal speaker.
This speaker is used for BIOS Beep Codes.

In the chart to the right, you will see GRD used many times.
GRD stands for Ground.
ANY Black wire in the twisted pair of wires, is a Ground wire.

Most of the eMachines I have worked on, use a Red, and Black pair of twisted wires for the Power On switch.
I could be mistaken on the T2542.

Best method, is to follow the color code of the wires that come from Pins 7 and 8, and be sure.

The manual is found here:https://support.gateway.com/us/en/emac/product/default.aspx?modelId=1511

If you know how to dis-assemble the parts of your PC, then try to clean connectors, display card, memory. The CPU mounting... be careful to remove the cooling fan then move the cpu retainer arm back and forth that is to regain better contacts of cpu leads. if you have an spare keyboqrd, try replacing it, if you have sa defective keyboard controller then you will have failure to boot sometimes. after cleaning the PC pheriperals, put it back and reset your BIOS/Cmos and configure as you neede, basic fail safe setup.

You will find (normally in the bottom right) 2 rows of pins sticking out of the motherboard. Some of these will have connections to them with wires coming out and going to the front of your cumputer. Look for a free space usually about 2 or 3 pins, marked PWR, O/I or PSW. Alternatively it may be color coded Blue or Green is usually the color for the power switch. I have attached a picture of an e machine motherboard showign the location of the connectionsOne of hte pins might be marked with a + this can be ignored if you are just connecting the power switch.

1. Your OS has become corrupt! Either you have to format your system OR you can try System Restore.

2. Restart your system and press F8/F9 during booting continuously.

3. Select 'Last Known Good Configuration' option from the list.

4. System will restart and boot.

tell me if it works...tc! :)

You really aren't giving much info, so here are some beep - codes, also make sure nothing came loose on the motherboard or other components ( do this ONLY if you know how ) Safety first.

The eMachines T3516 uses an Intel D101GGC motherboard,http://www.ascendtech.us/intel-d101ggc-lga775-800fsb-motherboard_i_mb4intd101ggc.aspxTwo Ram Memory slots.Maximum Amount for EACH ram memory slot is 1GB.Maximum TOTAL Amount for the motherboard is 2GB.Ram Memory used is DDR Sdram at 333MegaHertz, or 400MHz.That is PC-2700 and PC-3200 respectively.Uses Non-ECC, low density, Unbuffered, CAS Latency of 2.5, and 2.5 Volt.Regards,joecoolvette

AGP is your video card slot.http://reviews.cnet.com/desktops/emachines-t3085/4507-3118_7-30826600.html

Look for a heatsink fan based on the CPU chip set. Like LGA775, but double check your CPU. Gateway / Emachine pointed me to:http://support.gateway.com/s/PC/eMac/5646/5646cl3.shtml Good Luck

restart your computer repeatedly tapping the f8 key to enter safe mode while the screen is black once in safe mode where the only things working will be your keyboard and mouse allowing you to attempt to repair your computer

Reboot the computer As the computer is booting repeatadly press the F8 key as the computer is booting

If done properly the user should get to a screen similar to the below screen.

Select the option for Safe mode command prompt only

Windows Advanced Options MenuPlease select an option:

Safe ModeSafe Mode with NetworkingSafe Mode with Command Prompt

Enable Boot LoggingEnable VGA modeLast Known Good Configuration (your most recent settings that worked)Directory Services Restore Mode (Windows domain controllers only)Debugging Mode

Start Windows NormallyRebootReturn to OS Choices Menu

Use the up and down arrow keys to move the highlight to your choice.

select safe mode with command prompt

Then type at the C:\> prompt: typeDEBUG and hit Enter. You'll see a dash (-) at the DEBUG prompt. Now type: o 70 2e which will show as -o 70 2e at the DEBUG prompt. Hit Enter. Then type: o 71 ff and hit Enter. Finally type: Q and hit Enter one last time to quit DEBUG back to the C:\> prompt. Now you're ready to reboot your PC, and press the appropriate key or key combo (look it up in your motherboard manual if you don't know it) to access your BIOS Setup.

Youll notice the password is gone.

if this fails try typing

At command prompt type debug you will get a - prompt where you can type the following (<enter> means press enter, not type enter*)A <ENTER>MOV AX,0 <ENTER>MOV AX,CX <ENTER>OUT 70,AL <ENTER>MOV AX,0 <ENTER>OUT 71,AL <ENTER>INC CX <ENTER>CMP CX,100 <ENTER>JB 103 <ENTER>INT 20 <ENTER><ENTER> just hit enter on this lineG <ENTER>Q <ENTER> Basic BIOS password - works 9.9 times out of ten

if this fails you will need to

Select safe mode with networking to download

you could download all of these or just one save them to a usb drive for later use if one fails to remove the password

A CMOS BIOS password recovery tool

Editors note: This tool should only be used by experienced computer users. Please see the enclosed read me if you would like to run it from Windows. Failure to follow instructions (from Windows) will cause your anti-virus to flag this as a virus. hope this helps

what OS ? Frankly this question has been answered so many times, you SHOULD be able to find it by searching for :lost password (whatever OS you have)Tallon41

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Test all power and data leads that attach to your hard drive IDE,SATA

the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty or just replace them they might be faulty

if its a 40 pin flat ribbon type it will be the first to fail

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty

even something as small as a faulty electrical fan and its lead can cause you problems

computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error

make sure your graphics card is securely seated with no dust built up or in the socket

if you remove your graphics check the socket to make sure its dust free

restart your computer then reinstall it this should activate found new hardware wizard

hope this helps

You can use Smartkey Windows Password to help you to reset computer password, and see the detail direction from http://www.recoverlostpassword.com/products/windowspasswordrecovery.html

from what I know, you are probibly going to have to re-install whatever version of windows you are running. atleast its not too expensive

When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Make sure via nvidia website you have the latest driver for your particular os if not download it and install. Hope this helps.
