My computer turns on with the fans at maximum speed and stays at max speed usually they go to normal speed after a few seconds when my computer turns on the hard drive turns on but nothing happens it just sits there running at max speed nothing appears on the screen except it says "no input signal" but its plugged into the computer, but the monitor i think is not the issue it just wont start up thanx

Re: computer goes on but does not boot
When you start up the PC, do you get any kind of beep sound? If not, I would reckon the RAM modules are faulty and would need to be replaced first. That is the usual cause for this kind of issue. Also when replacing the modules, make sure they are the type supported by your motherboard, ie DDR, DDR2, etc. You will have to consult your m/b manual for this..
If the problem is not with the RAM, ie you hear a beep, but nothing else, I would guess that the MBR of your operating system is dysfunctional, which would mean that you would have to reinstall the operating system.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

This is a diagram of a blower relay and a fan motor, the normally closed fan relay switch goes to the low speed which is the Heat speed, the low speed is controllled by a temperature delay depicted in the low speed circuit.
The normally open fan relay switch goes to the high speed, which is the AC modes speed , also if you run the fan continuously via the fan switch on the thermostat this is also to high speed.
I suspect the temperature delay's on setting is being reached thus cycling the low speed of the fan.
Sensors do not always throw codes if they are close to normal parameters, needs to be checked with a scan tool and thermometer.
There is usually a high and a low speed fan relay, as well as a separate A/C fan relay (also high) Your High speed fan relay could be bad, or the fuse for it.
Engine idle surging usually means the coolant is boiling and there is no longer liquid in the throttlebody causing it to go to a high idle because it thinks the engine is cold. Warm coolant closes a valve lowering the idle on most Japanese makes of that year.
Also, sometimes Thermostats stick half open and do not allow enough flow. AND sometimes in neglected cooling systems Water pump Vains are eroded by electralosis causing low coolant flow as well. And a Clogged radiator can also cause this, as by the time the fans run on high it's to late.
More likely it's your fan speed switch. If the resistor pack goes bad, usually fan only works on high speed, but is still turned on and off by the fan switch. If yours stays on all time with key on, and won't turn off by the fan switch, probably a bad fan switch.
The resistor will be on the heater case, mounted with two small screws, a small rectangle with a wire connector with 4 or 5 wires to it, and not far from the blower motor.
I do not know the maximum distance, but there should be a wear indicator on the tire. Usually the max speed on doughnut tires is around 50 mph but the owners manual will clarify. Usually the spare will have a max speed posted on it somewhere with a sticker.
Please let me know if I can further assist you.
Check the energy save settings and see if the monitor is set to shut off after a certain amount of time. Also if the laptop battery gets low it may start to turn off the monitor to save energy. Are you using the computer on a/c power or battery power when this happens? As far as fan controls the settings are usually in the bios but you can sometimes install software that will control the system fan. The BIOS system menu is usually available by pressing delete when the computer boots up(some computers are different button).
try reinstalling your windows your OS might be corrupted from a Virus infection. viruses or worms usually hog your Internet , that might result to a slow internet connection..
Also if you have a 256kbps connection, your download speed of 25KBper sec is normal
because 256,000 kbps / 8bits = 32 KB/s (thats your maximum dl speed)
but assuming there is a loss in transmission about 15- 20% lost your max dl speed is only 25.6 KB/s thats why your connection is normal.
I had this happen sometimes after a windows update/reboot. If the computer is on, hold down the power button until it cuts off. Unplug the power cord. Wait for a couple of minutes. Plug the cord back in, and turn on system.
