Gateway DX4822-01 desktop computer crashes but powers back up after a cool down period. I thought it was a mother board issue and replace the mother board but the same thing is occuring with the new


It is most likely the cpu fan, check to see if you have enough thermal paste on cpu, if not apply a little more and see if that resolve the issue.

When I turn on my packard bell ixtreme 6052 nothing appears yet it does see computer but does not even go to bios and harddrive read light remains on and harddrive is constantly ticking like it's...


This could be lots of things (bad HD, bad Mother board, bad RAM,etc...) first you need to narrow down the possible cause, open the computer, take out every thing that can be unplugged (I MEAN EVERYTHING) RAM, PCI cards, VIDEO cards, all storages HD, CD ROM, etc... just leave the CPU and power supply plugged in, than power up the computer and listen for BEEP's if you hear a series of BEEP's this means the CPU, power supply and mother board are GOOD, than (with power OFF each time) re-install the components you taken out (ONE at a time) to see which device causes the system crash... I've seen a modem card causing a system mall function once rediculous but true...

Good luck!

Emachine will not power up


By nothing else, from a technical standpoint this would mean literally nothing, the CPU fan, power supply fan, aux fan, disk drive not spinning up, etc. My experience with EMachines is their motherboards aint the best, have been known to take out hard drives and other peripherals to the mother board. If you are technically inclined the first thing to do is to bare out the system, Power Supply attached to the Mother Board w/ Cpu Monitor and Keyboard no Hard Drive and no Non esential boards installed, very carefully remove the memory and start it up all should be fine except it should give you a long beep from the PC Speaker indicating the Mother Board is aware there is no memory installed if it will not do this most basic of tests this is not good. If it does give you a health beep continue to install one item at a time, first the memory, the display should, if working, tell you there is a boot failure, of course, the hard drive is not connected, do so and keep on testing. Without knowing what type of mother board you have, most likely an AT with integrated peripherials the process to determine exactly what the problem is would take hands on trouble shooting. If you dont get the beep indicating the mother board cant determine if memory is installed and truley nothing else is on it is more likely the mother board. There are several good ones online that will fit your case if you want to go this route. Or is it time to upgrade ?

THE SCREEN SMEARS NAD SHUTS DOWN


Hi eakesj:
A number of things here should be checked.
First shut down and remove all cards, and power connections to all the drives such as cdroms, hard drives.
The power supply should also be looked at and tested for correct voltages on each wire. This can be done with a voltage meter.
Turn on the power and see if you can get the machine to start to the bios screen. (this will work if you have a video processor on board, if you have a video card, you will need it to use the monitor).
If that will not work, then you have more problems than you thought at the beginning.
If the mother board will not work at this point, then you have problems with either the mother board or the cpu processor. There is a possibility that there are problems with the memory modules.
So, if you have only one memory module, then I would remove the memory, carefully clean the contacts, (a clean pencil eraser can work, if you are careful, and do not press very hard) and then plug the memory back in and try again. Also if you have extra modules of the same type, try one for testing.
If you are still having the same problems, then the mother board or the cpu is the problem. At this point you should consider if you want to continue and repair or buy another mother board of the same size. If you buy another kind of mother board, remember you will have to re-install your operating system over the original one to get the complete setup and the bios to work correctly with it. Many times this can be done, but you risk losing data (you will lose all data in MY DOCUMENTS), and may have to completely re-install the OS. You may want to install the drive in another computer as a slave and back up any data you want to save before you proceed.
If you decide to continue with your original mother board, and still have problems, then the cpu or the mother board is suspect. To test the cpu, either test your board with another cpu which is compatible, or check the mother board with another mother board of the same exact model.
Hope you find the problem.

Sounds like you tried everything except reseating any other hardware that may or may not be placed in another socket such as PCI, AGP, etc... Like a Modem, Network adapter, Sound/Graphics card, Wireless card, etc... This is probably a wasted post as if you knew to check each stick of memory seperatly then you've probably already reseated all socketed hardware. Though, you could remove all non essential hardware such as I mentioned above and try installing Windows again?
Good luck and keep us posted.

Pc starts and runs but wont boot up monitor shows no signal


1) When you turn on the computer, watch and listen for:

a) power supply fan, (power is on)
b) chassis lights (power is on)
c) ticking sound during memory test
(the BIOS POST is running)

d) beeps or rhythmical error codes
(POST failed, bad CPU, CHIP set, memory or video)

e) Monitor either comes on, displays garbled video,
displays a No Sync or No Signal message...

No depending on how far it gets:

Check power supply, cables etc.
Check video cable.
Check monitor with a different PC

Now unplug the power cord, with the computer still
on, this will help drain any internal capacitors.
Wait 5 minutes, then shut off the switches,
and open up the box. try the following,
one at a time:

2) Remove all I/O cards except the video card,
and don't plug them back in until the problem
is fixed. Unplug all the ribbon cables from
the mother board as well:

Hard drives, CD drive, floppies etc.

Make sure you make notes about how to plug it
back in, and cable orientation !!!

0) Re-seat all power cables: Red, Black Yellow harnesses.

1) Unplug and re-seat the video card

2) Similarly, re-seat all memory SIM/DIM modules,

3) Re-seat the CPU

4) Replace the video card

5) Replace memory, CPU or whole mother board,

Plug the good parts back in one at a time,
and test the machine.

Save for the power supply, there really is NO way to test
and isolate a bad module except by swapping/ trial and error
because of inter-dependencies.

For example a bad I/O card, any I/O card, can short circuit
the I/O bus, causing all other plug-in cards to stop working,
or even the main mother-board to freeze during the POST.

A bad power supply ditto.

A bad memory chip ... ditto.

The type of electronic instruments required to actually
test modern computers running at Gigahertz speed cost
hundreds of thousands of dollars, some cost millions, and
are only available to hi end manufacturers

Even the power supply will not power up for a voltage check
if the mother board is bad, although you can use a jumper
on the green wire to ground to force it on, when you unplug
the power connector from the mother-board, if you are brave.

Computer shops carry a lot of spare parts, and their service
department has gutted computers rigged up as test jigs.

They trouble shoot your system by either plugging your
stuff into their jigs, one at a time, or by plugging known
good components into your computer until the problem
is fixed.

This if of course possibly dangerous, since one bad part
can also fry other good parts that plug into it, or that it
plugs into. The compute shops, of course charge you
enough to make up for this.

If a computer is partially operable, it is also possible to
run software diagnostics.

If not, swap and pray is the only way.

Hope this helps

Please rate my answers, martin.

My computer keeps freezing and crashing can you help


Try the following for a freezing or crashing computer:
1) General maintenance - open the computer case and blow out the dust with a can of compressed air (do not shake can).  Aim air at CPU fan, power supply fan.
2) Turn on computer, does the CPU fan spin?  It should
3) Turn off computer, remove memory modules and reinsert memory modules.  Take care to make sure they are lined up correctly, they can only go in one way.  Use the tabs to remove them.
4) Make a Memtest CD from www.memtest.org.  Follow the instructions there to test the RAM for bad memory chips.
5) Make a knoppix live cd from www.knoppix.org.  Follow the instructions there to boot into knoppix.  Does it crash when running knoppix?  If not it could be Windows that is the culprit.

I am sorry if I don't understand, "the disk to crash my p.c."? Do you mean that you don't have the disk to get p.c. fixed that crashed? Your p.c. crash and you can't get going? 1) What kind of p.c. do you have?[Dell,IBM,Compaq, etc.] 2)How much memory?[RAM that turns on the p.c.] When the memory chip goes bad,or in moving the pc, the chip can be phycically disconnected from mother board.Will provent pc from turn on.
