fan spinning too fast + monitor no signal

March 16, 2013 at 06:41:02
Specs: Windows 8, I'm not sure/10 gigs
Hey, something fairly weird happened.

My first problem is that when I attempt to turn my monitor on for some reason it decides to give me a no signal. The computer is on when doing this and I tested my monitor on another computer to see if the same problem persisted, it did not. This makes me assume there's a problem with the computer I am using, but it could be something else I'm unaware of.

The second problem is that my computer's (the same in the above situation that the monitor wouldn't work with) fan seems to be spinning too fast. I looked it up to see why and a lot of what i found seems to attribute it to overheating, but my computer doesn't feel heated/overheated. Others have said it could also be dust, but the computer is spotless. Other than that, I couldn't seem to find any helpful information.

I am in no way a computer expert, I'm novice at best so I could really utilize some assistance with the situation I am currently in. If there is any more information you need to assist me with my problem, I will do what I can to provide it.

The "no signal" error should be fairly obvious. The monitor isn't receiving a video signal, that means the problem is with something within the computer. Could be the graphics card, motherboard, CPU, power supply, etc.

The high speed fan indicates the CPU is overheating. The system is trying to lower the CPU temp by increasing the fan speed. You can't tell if it's overheating by "feel", you need to run a temp monitoring program or check the BIOS. Unfortunately, if you can't get a display, you can't check the temp.

You didn't list any specs but since your system has 10GB RAM, is running Win8, & has a monitor, it's most likely a relatively new desktop. Is it a custom build or store bought? What's the make/model? Did you do anything inside the case that may have brought this problem on? Did you do any cleaning, install RAM, mess with the CPU heatsink, etc?

You also posted in the wrong forum, this should be in hardware.

It's store bought, not entirely sure what make/model (I believe it's hp envy h8-1534), I did not do anything inside the case that would bring this problem (or do anything with the case at all).

I also apologize, I wasn't too sure which forum this belonged in.

Is this it?

"I did not do anything inside the case that would bring this problem (or do anything with the case at all)"

Just to clarify, you said "the computer is spotless". How would you know without opening the case & looking inside? Have you determined which fan & running at high speed? Maybe it's the graphics card fan?

I opened the case, I just didn't do anything inside of it outside of check it (sorry for not making that clear in my previous post).

Also that is the computer!

EDIT: Alright, update here: I tried putting the computer back on and etc. and the fan is fine now. Back to normal speed. Ill assume it was caused by overheating previously (or perhaps something I'm unaware of), but the immediate problem is the no signal now. What's the best idea here?

Your system has a Gigabyte motherboard, these motherboards typically run the CPU fan at maximum RPM during boot up and shut down, and basically whenever the motherboard drivers are not loaded (as in Windows is not starting). Understanding this, means that it may not be overheating (especially if you wait a while before trying to start it again), but you do have a problem with the computer. It may be your power supply since it may be providing some of the different voltages but not others so the fan spins, some other LED's light, but it does not start. It may also be related to other hardware as well such as hard drive, memory, and possibly other components.
It sounds like your system is fairly new, if it is still under warranty, it is best to take it back or call HP tech support before doing too much, especially anything that might void your warranty.
If it is not under warranty, try to think of anything unusual the system was doing (even sounds) recently and post back that information because anything might be a clue to what is going on.

You have to be a little bit crazy to keep you from going insane.

Yep, it is still under warranty. I'll call HP tech support first and if all else fails, I'll take it back. Thanks for the advice!

EDIT: Unless there's a different solution, but I understand that it may take several different ideas in order to fix the problem so I rather not make the warranty void (like the above said) if one of the solutions do end up making it void.

Opening the case may have already voided the warranty. If there was no seal on the case then you may not wish to volunteer that information. There may be a way for tech support to know you looked in so don't lie about it. (Some cases have intrusion sensors)

video card is bad---a lot of mother boards have a built in video card--so if it goes bad--you will have to install the proper vga card into the mother board---most of the vga boards are PCI cards--but there are a lot of different ones to use--your mother board will have a slot for the video adapter or card-a lot of them look different than the rest of the slots-especially the newer boards-------Curtis F
