Question about Computers & Internet

1 Answer

Good day, I inserted a memory into my second memory slot. When i plugged the unit, the slot started to smoke so i quickly removed the power cable. Since then the system has refused to start. The keyboard indicates and also my mouse indicates but the monitor won't show anything. Also, i observe the hard disk indicator in front of the casing is constantly on instead of blinking when i start the system. I tested my hard disk and my memory on another system, they are still fine. Please what could be the problem?

Hi there,

First of all does your power supply smell of burning?.... if so than you need a new power supply, otherwise you may have blown you motherboard which may include your cpu.

Please let me know what you find and I may be able to help you.

Regards,

Philip

My acer aspire 5742z worked perfectly for 1st year but after a year and a day crashed and will not start up anymore. When i hit the start up button the blue light comes on but turns off again in a matter...


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Remove the battery, Remove the cover that houses the memory on the bottom of the laptop then remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

I tried to change the ram on my asus laptop and turned it on and screen does not show anything but laptop turns on but black screen help me?


Good day.
Memory modules are sensitive. You must take a lot of care when handling memory modules.
The first question is why did you change the ram? Nevertheless, if the one you replace is certified in good condition, then the problem lies in the insertion of the new ram. First to note is the use of correct memory module type and speed. Use of incorrect type/speed may result to errors. Secondly,clean the module's contact points using an eraser. See to it that you align the module's cut (located in the contact point) to the proper slot in the memory module's slot. Do not force to insert the memory module if it is not in the proper slot, it will break the board and/or the memory module. You can hear a slight click sound or a firm position signifying you have correctly inserted the memory module. Power on test your laptop. If you have more than one modules, you may try one another to isolate defective one.
Feel free to post your problems here at Fixya.
Good luck.

It is stuck in power saver mode tried every thing can not get in come back up. Tried turning off and on, unpluged and pluged back in, put in cd, tried starting in safe mode with F8 key.


Possible that it's caused by a faulty hardware

1. Remove all the connection at the back of your computer
2. Power cycle your computer tower by pressing the power button for 15 seconds
3. Plug the power cord back in and monitor cable at the back of your computer tower (if it turned on, meaning that one of the device plugged at the back of your computer is the one's causing the problem, for you to pin point the problem, try plugging it one-by-one and turn on the computer each time you plug a device)
4. If it keeps on doing that, open up your computer tower (be careful to unplug the power cord and power cycle it to avoid static electricity)
5. Reseat the video card, turn on the computer again, if it's still occurring
6. Reseat the IDE/Sata cable of your hard drive and try to make sure it's properly plugged in, turn on the computer again, if it's still occurring
7. Reseat the memory, turn on the computer and test it again if the same thing
8. If you have 2 memory chip inserted in your computer tower memory slot, remove the other one and turn on the computer, do the same thing to other memory and each slot
9. Reseat the CPU and start the computer.

Unit won't power on.


Hi,
Having a wide knowledge of Laptops.
i,d suggest, removing the RAM/Memory. And swapping slots ( if 2 sticks are Present ) try starting with 1 stick inserted into either/any slot. This will eliminate ( faulty Slot on Motherboard )
Secondly. remove and re-seat The CPU ( processor Chip ) reseal with Good thermal Compound ( Arctic-Silver Or Similar )
If either of these don,t work the fault lies Within the motherboard.

At start you 3 beeps and fans come on and nothing else


You have a memory error...MABYE:

Look for the motherboard online and see who's bios it has, and its error codes.

Remove all memory...
Now, you dont know if its the slots or the memory, take ONE stick of memory, and place it in the first slot, start er up. then take that same stick, and place it in the second slot? Same result? Then take a diffrent memory stick and place it on the second slot.

Dell Inspiron 600m not starting up!


I had this same problem with my 600m laptop.  How many times do the lights flash, before they stop flashing?

Cause: There is a physical problem with the computer that it is detecting at startup diagnostics.

Solution:
You should have two pieces of RAM installed. Carefully, remove the memory slot cover.  Swap the 2 pieces of memory you have in there (please follow memory installation and removal for laptops to the letter, by never touching any of the electronic contacts and handling the memory from its sides). Make sure, they sit in the slot properly (to the best you can see). Then, place back the memory cover, very carefully, and screw in.  If you see the memory door cover not closing properly, the RAM might be improperly inserted.  Please go back to the swapping of RAM step. :)  

If this didn't work, 1 of the 2 RAM's you have are no longer functioning properly. Please follow the steps to openning the memory door again and remove RAM in "B" slot first.  Then close it and try to start the computer.

If it still doing the same light flashes, open the memory door and remove RAM in slot "A".  then place the RAM you removed from slot "B" into slot "A".  Then start the computer again.

My Acer Aspire 5000 won't turn on. I hit the power button, the light turns on for half a second then blinks off again. The HD doesnt start, neither does the fan and the screen never coms on. The battery is...


Hi,
sounds as if the laptops in hibernation or sleep mode.
Try refering to the user manual regarding the mentioned points.
also try alternating the memory from slot to slot, 1 faulty slot or ram module, will cause the computer not to boot.
Finally, if this is a model that has a ribbon-cable from power switch, to motherboard. ensure it,s inserted correctly/square et,c.

Hope this helps, thankyou for using Fixya.
