1. Unfortunately some people call the computer the modem. This is not the modem overheating but most likely the cpu. If you open your computer and look straight in at it, there is a fan. It should be running at all times. Also make sure that it is free of dust. Dust build up on and under the fan in the heatsink will cause tremendous heat issues causing your computer to just shut down. Get some canned air (available in all retail electronic store departments) and blow out the dust from the inside of your computer, especially the fan and heatsink.
2. Another cause could be a bad power supply, where some of the voltages drop so the computer just either locks up or shuts off. I place my bet on a dirty cpu, though.

My fan is running but it won't load windows. The monitor says power saving mode


Check the NUM LOCK led status when power on the computer if it is on and off when you press num lock key that means your cpu is working fine only issue with screen resolution for that when you power up th computer press F8 key 5 to 6 times then you can see safe mode and other menu.Enter in "enable vga mode " then go to display settings change scree resolution to 1024*768 then check. but if num lock led stay constant then open cpu cabinet cover reconnect RAM memory.Pull cmos cell from motherboard for 10 minutes then put it back. Reconnect pci or vga card if any. Reconnect processor and it's fan. Make sure motherboard is not ground with cabinet.Also make sure harddrive is recognized in bios if you are able to see bios. For that when you power up the computer press F1 or F2 or del or ALT+F2 key to enter in bios then check. Let me know if you need further assistance. Thanks for using Fixya.

Urgent problem with my relisys monitor, please help!


sounds like an overheating problem. you can try blowing out the back of the monitor, or putting a fan close to it. If it is really dirty it will shut itself off so as to not get damaged. is it crt, or lcd?

Screen does not turn on but green light is on.


Green light indicates the monitor is getting power. Nothing coming up on the screen indicates, No Signal.

No signal from the computer. This means the computer itself isn't working.

A bad power supply in the computer can cause this. A bad power supply is the leading cause of desktop computer failure. It is replaceable, and can be done by the owner relatively easy.

You may have a computer tower that the Power light comes on, you hear fan/s spinning, (Including the Power Supply fan), and it sounds like the harddrive is running.

ALL the lights in your computer use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
A harddrive sitting there spinning in an endless loop, consumes about 2 to 3 Watts.

A Processor uses 51 to 125 Watts. Depends on what Processor it is.

A weak Power Supply will have enough power for lights, fans, and that harddrive sitting there spinning.
It won't have enough power to turn on the Processor.

[No processor operating, then the harddrive sits there spinning in an endless loop, because there is no processor to find the boot sector]

For a test, connect your monitor to a know good computer. See if it works.
Now connect that other monitor to your computer.

No signal when power button turn on


Sounds like either the power supply unit's fan isnt functioning and the the uniy over heats and the computer then wouldnt boot up (to protect itself) or the processor is overheating. But rather seems like a power supply problem

My computer keeps beeping when I turn it on!!!


OK.

Thy to identify RAM, remove it and clean the contacts with a rubber (the same you use to erase the pencil marks).

Put the RAM again and try to boot.

-------------------------------------------

Another problem can be the temperature...
Remove the fan (and clean it)
Remove the heatsink (and clean it)
Put new thermal compound

put back the heatsink and the fan (connect the wires)

check your temperature in your BIOS

CPU Fan Speed Too Low or Fails***


There are three things you need to have a good gaming computer, fast graphics card, fast CPU, and lots of RAM. You didn't list your RAM so I can't help you, but 4GB is the most you can put in a computer. If you want to know everything about your computer then click on Start>Accesssories>system tools>system.

Ok you asked four or five questions so lets start with the CPU since if that breaks nothing else matters. First, the measurement for CPU is GigaHertz (GHz) not rpm. So it looks like you have a 1.98GHz CPU. That is not extremely fast (my Dell laptop for instance has a 2.4GHz) so you don't have to worry about your CPU overheating. Yes, all CPUs should have a heatsink and a fan. It helps with the cooling. A CPU also does a thing called "throttling" if it is getting too hot it slows itself down to cool off. So you are good with the CPU.

The other fan is the large fan you hear going on and off. That is connected to your power supply. The measurement for that is in wattage, it is custom made depending on the motherboard so that is a given that there is no problems with the power supply.
Both fans on the CPU and the Power Supply will turn off and on as they get hotter then stop when they are cool again.

Your graphics card is the most important for gaming. It should come with its on RAM and it's on fan. GE FORCE makes some good ones. Just google "gaming graphic cards" and you'll get an idea of what you need.

So that's it. Hope this helps you understand more. If you have any questions let me know. Don't forget to rate this solution with four stars before logging out.

Monitor works for about 30 mins then goes blank with a messahe reading 'Not Optimum'


Hi Rick I have the same problem. Have you found a solution yet? I had the power supply tested, that is not the problem. It seems to go off when it gets hot. If I point a fan at it, it seems to last longer before blacking out. Pete
