Question about Compaq Presario SR1120NX 2.66GHZ Tower w/ CD-RW (2018267632) PC Desktop

PC totally locked

After a power outage, I can no longer power off/on my PC. I was in the middle of burning a DVD when the power in my building shut off. When it came back on, the green light in the front and back of the PC was flashing. I have a blank screen. I can't shut it off by CTR-ALT-DLT, holding in the power button or unplugging/replugging it. The screen is totally blank and nothing happens at all except the blinking lights. Any help? Thanks.

    My last question. I notice there is a bundle of cords connecting from the power supply to the mother board. Does this just snap off the mother board. It appeared to be "stuck". The plug was much like the one that plugs into the hard drive. Thanks.

    I am having the same problem. I unplugged the power supply from the motherboard and unplugged the computer from the wall. the light on the back of the computer is steady green. I am assuming it is not the power supply. I will check each component one by one until it flashes... correct? This way, I will find the defective component??

The motherboard could have been damaged when the power came back on or damaged the power supply unit.

The flashing power switch and power supply LED on the rear in conjunction with a power failure or surge indicates that there is a defective component; typically the power supply, motherboard, memory, processor or modem. -Disconnect all the power supply leads, drives, and motherboard as well as any USB, firewire and other external devices. -Plug in the 115v power supply cable and look at he LED on the back of the power supply. If it is still flashing the power supply is bad and needs to be replaced. -If it isn?t flashing then unplug the power supply plug in one device, plug in the power cord and watch for the flashing LED again. If it?s flashing you?ve found your culprit, if not move on to the next component and repeat the process until you?ve found it. Don?t forget your plug in cards could also be the problem. Good luck and let us know if you have any other questions. As always please don?t forget to rate this posting.

    On one of the long sides of the connector there should be a plastic lever. Push against the lever top and then rock the connector back and forth while gently pulling on it. The connector is snug but once the lever is depressed it should come off 'fairy' easily.

Dell latitude D600 I was running without a battery when there was a brief power outage. The laptop shut down, and will not restart. It appears to start, but screen never comes on, and after about 30...

Try flexing the whole bottom assembly. that is with the laptop open put your knee in the middle and grab the unit with one hand on the corner closest to you and the other near the screen and put enough pressure to "flex " the mobo right after you push the start button if it doesn't start try it the other way... this has been working for my grandsons d600 for 6 months. i tried a new switch board because the guy that sold me the mobo said the plug for that is known to crack and that didn't fix it. good luck ps you will know it has worked when the 3 lock lights go out and the power light stays on.

Code error

Before following the suggestions given below please make sure that you have the latest firmware for your DVD burner drive. Please contact your vendor or visit the manufacturer's website for the latest updates.

Please follow the steps mentioned below to resolve the issue:

1) Empty the contents of the C:\Windows\temp folder and C:\temp folder, if you have one. Then empty Recycle Bin.

2) Defragment your hard drive. DVD video files are very large and can quickly fill your hard drive to capacity. A fragmented hard drive can cause problems during DVD burning. Make sure to defragment your drive(s) regularly.

3) To avoid any compatibility issues, please close all other software and utility applications including virus scans, screen saver and instant messaging software before you launch PowerDirector.

4) Increase Virtual memory :

1. Right click on "MyComputer"
2. Select Properties -> Advance
3. Click on "settings" under Performance.
4. Select "Advance"
5. Click on "change" under Virtual memory.
6. Select "Custom" and enter initial value as "512" and Max value as "3096".

NOTE: If your existing settings are higher than recommended then leave them as before.

5) Please check whether the drive where you have installed Power Director software has enough space on it. At least 15 GB of free space is required and recommended while burning a DVD.

Now, try to burn the DVD at low burning speed.

If the issue still persists, try to uninstall other CD/DVD burning software like Nero, EasyCD Creator, Direct CD etc. Two burning software installed on same computer are known to cause conflict due to common files in them.

Also disable the XP built-in burning software. To disable the Windows built-in burning software:
- Open My Computer.
- Right-click your CD-RW or DVD drive and click Properties.
- Select the Recording tab.
- Remove the check mark from the 'Enable CD recording on this drive' check box.
- Click OK.

Also make sure that the total size of the video does not exceed the disc limit. (It is recommended that the total size should be less than 4.3 GB)

Now, close all other software and utility applications and then try the 'Create a DVD folder' option in the burning options screen and let us know of the result.

If the DVD folder is burned successfully, then the issue is burner specific and not software specific.

If the issue still not resolved, you may need to reinstall the Power Director software. Uninstall other burning softwares and then reinstall Power Director.

Follow the steps given below to reinstall your PowerDirector. Before installing your program, please close your MSN messenger, since we found that MSN messenger my lock some installation programs.

i) Uninstall PowerDirector software:

a.)Start--> Programs -->Cyberlink PowerDirector --> Uninstall PowerDirector

b.)Start --> Run --> type "regedit" --> click "HKEY_LOCAL_MACHINE" --> click
"Software" --> click "Cyberlink" --> "PowerDirector". Delete folder "PowerDirector".

c.)Start --> Run --> type "regedit" --> click "HKEY_CURRENT_USER" --> click
"Software" --> click "Cyberlink" --> "PowerDirector". Delete folder "PowerDirector".

d)Reboot your PC.

ii) Reinstall PowerDirector. (NOTE: Before installation please close MSN Messenger, if open)

Now try again to 'Create a DVD folder'.

Go ahead with burning DVD only if the DVD folder is created successfully and without errors.

Melting plastic smell/ computer slow and shuts down after about 15mins

Hi there.
The reason you can smell burning plastic and why its shutting down after a short time is because its overheating. This can be caused by a build up of dust on the CPU fan, overtime with dust build up computers struggle to keep themselves cool and tend to shut down unexpectedly, chances are this is the problem with your machine, my advice would be to remove the power cord, open the side panel of the computer and clean all the dust away from inside the tower, do this with a soft, clean paintbrush making sure you remove the dust carefully and gently, also make sure the CPU fan and the heat sync behind it is completely free of dust or any other foreign objects.
Once you are happy that its clear of dust, close or return the side panel, plug in the power cord and turn the PC on, you may find that the PC will stay on for longer with the smell dramatically reduced.

Please post back with the results and thanks for using FixYa!!

Electronic AC shuts down during power outage.

When I read this...this only tells me that some people are only as bright as a 15 watt light bulb.

You know they have these things on there to keep you alive, instead of catching on fire and killing you with smoke.

Leave it alone and follow the directions. You will live longer.

Burn errors cant get drive to write

It looks like from error codes that yoi may have a hardware error, or a disk format problem, if this is only burning problem you have on pc and it worked before, then uninstall and reinstall Nero, info gathered from here,
sense code 5 ASC 2c= 5 / 2C / 00 COMMAND SEQUENCE ERROR
5ASC2700=5 / 27 / 00 WRITE PROTECTED
Please give good rating if this helps you or points you in right direction, thanks
