computer over heating?

Posted on 2009-04-10
Last Modified: 2012-06-27
Computer will run for a while then all of the sudden the screen will go black and will have a small white box with multiple colored lines going vertically through the box. I ran a full systems hardware check and all hardware passed the test. I went to even viewer and the only error it showed was error 7022. "The HP CUE DeviceDiscovery Service service hung on starting." that is what the error says. It seems to me it only does this when the fan is not getting all the air it needs. It is running windows vista. Any ideas on what exactly causes this and how to fix it?

The 7022 error does not mean it is over heating, it means that the HP CUE DeviceDiscovery is stuck
but then again the process could get stuck due to a part over heating

i found a link that looks like a similar error to yours

The specified service is stuck in the start pending state. The service failed to indicate that it is making progress within the time period indicated in its last status message.

User Action
If the service does not restart, use Services in Control Panel\Administrative Tools to start the service manually. If the problem persists, contact the service vendor.

The 7022 error probably isn't related to the video problem you've described.

It is truly amazing, I have discovered in my years, just how much the video card can affect everything else in a machine.  Untold numbers of seemingly unrelated-to-video errors may be resolved by simply ensuring that one's video card is using the absolutely latest drivers; and that one's set of video drivers which are the most current are also the *ONLY* video drivers on the machine (e.g., that no old driver files are still lingering around on the machine).

I'm not sure I'd assume overheating until I first made absolutely certain that Windows itself is as up-to-date as it can be; that there are no hardware IRQ conflicts; that there are no viruses or other malware; that one's BIOS is flashed to the most recent update; and that all drivers for all devices are the most current possible.  Do all those things first, then see if the problem still rears its ugly head.

If you're right about it being overheating, then there's no substitute for better cooling.  That's just logical.  However, before investing in better cooling, first make sure that the cooling you having isn't being sabotaged by two things that I see more than anything else when it comes to cooling problems, and that's dust inside the machine, and caked on the blades of the cooling fans.  Dust is like a blanket sitting atop chips and other parts of the circuitry.  You would be amazed... stunned, even... by just how much dust can accumulate, and how thick it can get.  Every last bit of dust must be blown or vacuumed out of the machine, and all of its various vent holes.  But that's not enough...

...the blades of the cooling fans probably have dust caked-up on them, too... and that makes an AMAZING difference in their effectiveness.  One can even see that with ceiling fans in one's home.  If one simply takes a damp cloth and wipes all caked-up dust off the ceiling fan blade, and then turns it back on again, it suddenly feels like it's moving two or three times more air.  It can be amazing.  Same with window fans, bathroom fans, range exhause fans.  Restaurants routinely clean exhaust fans weekly for this very reason.

Computer cooling fans are no different.  And usually just blowing dust off of the blades of the computer's various cooling fans won't do it.  They have to be physically wiped off.  A fan -- any kind of fan -- with anything less than completely clean blades is extraordinarily inefficient.  And keeping cooling fan blades clean is perhaps the most overlooked cooling issue I've seen in my years of experience.

Another problem with cooling fans is bearings going (or gone) bad.  When that happens, of course, the fan must be replaced.  One can usually see the blade wobbling just as the fan is coming on, or shutting off; or perhaps there's even a bearing-sounding noise.  In either case, if the fan blade seems to be turning anything less than very freely and "lightly" (if one can imagine what that means), then it may very well have a bearing going bad... which, of course, slows-down the fan's RPMs.

After first making sure that Windows and its many drivers are in all ways as up-to-date as they can be; and that there are no hardware conflicts; then if you still suspect cooling,first make sure that the very basics of existing cooling are covered.  If you still need better cooling after that, then don't hesitate to install it.  More fans, or bigger better vents, or reconfiguring (partially covering) some vents so that air is forced across circuitry that's perhaps in a "hot pocket" area inside the machine... those are all included in the "basics."

If you need better cooling even after that, then perhaps the "basics" of your cooling was never sufficient in the first place.  If you built the machine yourself, that's a good possibility.  Much can be learned about cooling (even by people who aren't gamers and/or overclockers) from gaming and over-clocking web sites.  Those guys tend to be cooling experts.  I've resolved many a non-gaming-related, and/or non-overclocking-related cooling problem in an entirely non-gaming business office environment by implementing a few tricks learned over the years from gamer/overclocker web sites.

Finally, cooling problems on computers, just generally, are about common sense.  The general rule of thumb is that computers need to be "comfortable" just like people.  The old days of most computers needing air conditioning in a "coolroom" are probably past.  Most computers are designed to operate quite nicely in the same ambient room temperatures as humans find comfortable.  If the ambient temperature in any given room is warm enough that the humans in it are anything less than completely comfortable in their shirtsleeves, then the room's probably also too warm for the computers in it as well.  It's not rocket science.  Computers need coolish air drawn through them, just as humans need something less than warmish air surrounding them.  Again, inordinate refrigeration of the air is no longer necessary, but the air likely to be in an un-air-conditioned office in the middle of summer would likely be too warm.  Same with air typically found in offices at night and on weekends when the building's air conditioning may be turned off.  Such places are often too warm for computers.

There must be clearance around and above the computer, too.  If the computer is tucked into some kind of tiny under-desk or next-to-desk, on-the-floor little compartment, there may be inadequate ventilation around and above the machine.  Notebook users should also ensure that there's a little space beneath the machine so that a bit more air can flow.  Just sticking four little half-inch-round and quarter-inch-thick rubber feet (such as can be purchased from Radio Shack) onto the bottom of a notebook can make a huge difference in the airflow.  I have a high-end HP docking station for my notebook, and by simply mounting (with double-stick-tape) four half-inch-thick black rubber feet to the face of the docking station which comes into contact with the bottom of the notebook when it's in said station, I made the notebook's cooling fan stop kicking on so often, or so long.  It made a huge difference in the airflow beneath the machine... and so, now, the cooling fan in the notebook runs perhaps two-thirds less often as, and at about half the speed that, it used to before I installed the little rubber feet.  

Do not underestimate the importance of good air clearance around *ANY* computer; nor of the air which the computer's fans suck into being at least 74 degrees or below; and of the inside of the computer, and its various cooling fans, being dust free.  Never underestimate the importance of those things.  Beyond that, if the machine is still too warm inside, then begin using the kinds of cooling techniques which one may find on any good gamer/overclocker web site.  There's a wealth of good cooling information in such places.

try and disable the service HP CUE service and see if this fixes the problem.

because if it does not then it has something to do with the colling issue

Oh, yeah... and... I should have added...

If everything's so up-to-date that it's almost ridiculous; and if there's no malware; and there are no hardware conflicts; and cooling, in the end, doesn't really ameliorate the situation, then perhaps your earlier hardware testing wasn't sufficiently complete or accurate.  Perhaps the video card is bad after all; or just plain defective... a bad model... a lemon... or one which is perfectly fine when used with every other motherboard in the universe except maybe the particular one that you're using.  Who knows.  But I'd certainly first do everything I've earlier described and see what happens.

Something else to think about:  Computer self-testing has one flaw which, if one thinks about it, can easily be intuited, and that's that if the computer is somehow bad, then so may be the test results since, after all, the software being used to test is running on a bad computer.  It's a catch-22 of sorts.  Good hardware test results don't always mean anything... especially if they're not particularly comprehensive, or they don't truly exert the machine.

Couple things to check:
1) Is the problem with your videocard, or LCD?
Can you swap out either to see if the problem goes away?
If you had the case apart, did the videocard power supply connector get disconnected( if it had one of these connectors).

2) Check in the BIOS for the systemboard fan settings and set the fan speed to always on, and see what happens then. It might be that the temperature autosensing is not working correctly...maybe because the fan? is bad.

I also Googled part of the error, and ninja'd this solution from this link:
Well I wanted to let everyone know how this issue is being resolved. I have managed to resolve two of the errors and I am still working on one.

In order to get rid of the Service HP CUE DeviceDiscovery Service hung on starting for the HP Photosmart All in One 7280 series I did the following:

1) Click on the "Start Menu" icon on the bottom left corner of the screen , type "services.msc" in the "Start Search" edit box, and hit enter. This will trigger Vista to pop-up a "User Account Control" dialog to prompt for permission to continue. Click "Continue" to allow Vista to open the Services management console application.

2) The Services management console application is made up of 2 panels. The right panel contains a list of all services available on the system. Scroll thru this list and look for a service called "HP CUE DeviceDiscovery Service".

3) Right-click on "HP CUE DeviceDiscovery Service" and select "Properties" to open the "HP CUE DeviceDiscovery Service Properties" dialog.

4) From the "HP CUE DeviceDiscovery Service Properties" dialog, click on the "General" tab. If the "Service status" shows that the service has started, click on the "Stop" button to force the service to stop.

5) Change the "Start type" to "Disabled" and click on the "OK" button on the bottom of the dialog to apply the changes.

and the following:

1.Go to Computer,
2.Right click & select Properties.
3.Choose the Advanced panel. Click the first Settings button, in the Performance Section.
4.Choose the Data Execution Prevention panel.
5.Choose the first radio button, "Turn on DEP for essential Windows programs and services only

Now I just need to find the solution for the continuing application crashes and my printer software issue will be resolved. Wooo Hooo

I could not get this to do it more than once. i figured if i could not get it to keep reproducing i would just let it be until it happens more often. Thanks for all of the suggestions and advice.
