Replace the drive.

Some of the portable drives can be removed and placed into another enclosure. That is another route to explore especially if you need to retrieve data from it.

My computer cannot turn on the power, and i found a red led always on at the center near the rear portion of the mother board. is that something wrong with the mother board or just the supple power is...

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

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

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your "((MOTHERBOARD TO YOUR HARD DRIVE))" make sure they have a secure connection and are not faulty or just replace them they could be faulty
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 the electrical extensions or just replace them they could be faulty a computer needs its connections 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 extension or fan lead can cause this problem
follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every device and to have an end to be able work properly

a 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 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 hope this helps also it could be a dirty computer clean all of the dust from your computer you could use a vacuum cleaner but whatever you use make absolutely sure there is no moisture gets to anything in your computer

also check the Cmos battery and computer ram make sure they are securely seated

hope this helps

After 10 minute power failure the Code E1 F1 keeps appearing on display and will not allow me to clear or reset

the error code means that there has been a eprom error. Follow the directions below, if this fails to clear the errror code you will need to replace the control board.

1. Disconnect power for at least 30 seconds.
2. Re-apply power and observe for at least one minute.
3. If code re-appears, replace control board (also called ERC or clock).

Note: Applies to all F1-E... codes except F1-E3.

If you have any further questins please feel free to ask.

Where is the conputer for a 1998 sunfire

here are instructions from

REMOVAL & INSTALLATION See Figures 1, 2, 3, 4, 5, 6, 7 and 8


Fig. Fig. 1: The PCM is mounted behind the fender, adjacent to the EVAP canister


Fig. Fig. 2: Remove the module-to-bracket retaining screws and ...


Fig. Fig. 3: ... remove the PCM (1) from the mounting bracket (2)

    Fig. Fig. 4: Detach the PCM electrical connectors
                    Fig. Fig. 5: Remove the PCM (2) from the retainer (1)
                            Fig. Fig. 6: The EPROM cover is retained by two screws


                            Fig. Fig. 7: Remove the EPROM cover, if the seal tears, this is normal, do not apply an adhesive to the pad, the adhesive could drip onto the circuitry and ruin the PCM


                            Fig. Fig. 8: Remove the EPROM by squeezing the two tabs and carefully separating the EPROM from the PCM

                            1. Turn the ignition switch OFF .
                            2. Disconnect the negative battery cable.
                            3. Remove the right hand engine splash shield.
                            4. Unfasten the horn attaching bolt, then detach the electrical connector and remove the horn.
                            5. Unfasten the module-to-bracket retaining screws, then slide the PCM out of the mounting bracket.
                            6. Detach the electrical harness connectors from the PCM.
                            7. Remove the retainer from the PCM.
                            8. If you are replacing the PCM on a 1995-96 model:
                              1. Remove the Electronic Programmable Read Only Memory (EPROM) module, also known as the KS module, cover.
                            If the foam pad around the base of the EPROM cover rips during removal, this is normal and should not be remedied by applying any kind of adhesive to the pad. This could ruin the circuitry of the PCM.
                            WARNING Before removing the EPROM cover, thoroughly clean the outer surface of the PCM to remove any debris that could enter the PCM and cause damage to the circuitry.
                            WARNING To prevent a possible discharge of static electricity, which could ruin the PCM, do not touch the connector pins or the soldered components on the circuit board.
                              1. Remove the KS module by squeezing both retaining clips together and at the same time, grasp it at both ends and lift it up out of the socket.

                            To install:
                            Before replacement of a defective computer control module, first check the resistance of each PCM controlled solenoid.
                            1. If the PCM is being replaced, open the package on the new PCM and verify that the PCM numbers match or an updated number is given before you attempt installation.
                            2. If you have a 1995-96 model:
                              1. Install the EPROM into the PCM.
                              2. Install the EPROM cover and tighten the retaining screws to 25-28 inch lbs. (3 Nm).

                            3. Install the PCM retainer.
                            4. Attach the module electrical harness connectors.
                            5. Position the PCM in the vehicle, then install the module-to-bracket retaining screws.
                            6. Install the horn, attach the electrical connector, then fasten with the horn attaching bolt. Tighten the bolt to 6-9 ft. lbs. (8-12 Nm).
                            7. Install the right hand splash shield.
                            8. Check that the ignition switch is OFF , then connect the negative battery cable.
                            9. Enter the self-diagnostic system and check for trouble codes to be sure the PCM and the KS module are properly installed. For details, refer to the procedure for checking trouble codes.

                            Is there a reset button on a rca 38310 tv?

                            No   If it doesn't turn on then it has failed.  It either requires an eprom chip replacement, or the horizontal output transistor failed because of a dried out electrolytic capacitor.  Often the voltage rectifier needs to be replaced too

                            The best and probably the only way since it's a Haier is to transfer the old eprom to the new board. That's what we do. Good luck!

                            As you can see there are many U2 error codes. Needless to say, find your code and the replace the bad part. The battery is on the main board. The EPROM is on the main board.
                            If you find your code, replace the part and error still remains -- replace main board.

                            Yes , this sounds like the EPROM IC is failing or the crystal that keeps the frequency on the IC needs to be replaced , or even the buttons on the tv could be warped by the heat of the tv( if it is the buttons , then removing the control board from the plastic buttons will stop the random cycle and may make it so you can turn on the tv , but if not then it is the EPROM IC or crystal)
                            to check and see if the chip is messing up , hold down the menu button on the tv or vol up down and see if it stops cycling thru the video inputs
