When i press the start button the blue light doesnt come up, but I can hear the fan start (but its really faint and not as strong) all the other smaller lights come on like normal. i put the moniter on but doesnt show the computer actually starting up. by this time what i usually do is unplug the psu cord or shut off the power where the psu is connected to. if i turn it on right away, the fan now starts up the right way (really strong and loud) but stays at that same speed and doesnt fade like it normally would and the moniter doesnt show the computer starting u turn it on and it goes black and goes into like standby. if i wait maybe 5 mins and turn it on again sometimes the blue light comes back on and the computer starts up normally. at times i have to turn the computer tower around and unplug the psu cord there and put it back in really hard to turn it on. but the whole turning on and off switch is usually the way i do it every morning. a lot of the times im trying to start up my computer and it takes close to 20 mins. the psu cord is brand new (bought it for about 25 dollars maybe 2-3 months ago) and i did the whole canned air thing (removed all the dust). my computer cant be more than a year and a half old if i remember correctly. now for about three days i cant turn on my computer at all, (im my brothers lap top in order to type this btw) i would love any help! also, i have been thinking about taking my computer to circuit city or best buy for a diagnostic test but its so expensive and i have heard many horror stories. but the price alone worries me.
Same computer, same problem. Staples tech said motherboard but I dont believe they did a thorough diagnostic. I think this is a lemon law computer from Gateway and there should be some class action followup since this is a common problem with this model.
I was useing my pc yesterday night and i woke up 2day to use and i had the same problem fan running without stopping and no blue light and nothing displyd on monitor. i opned it and i cleaned it with air pump and its working now. so try to cleane it with a good air pump. i hope mine stay working. good luck all

Tip: The max point reward for answering a question is 15.
1. When you press the power button to turn it on, do you see any thing on screen, like the toshiba boot up screen or something like that. Or is it completely blank (black color) always.
2. Can you see a faint image of your desktop (try to see it in dark place with flash light). This is important to confirm.
3. Also, when you press power button, do you see the LED lights on laptop blinking or solid green (which ones are in blinking/solid) and do hear any sound ? Or do you feel that your laptop doesnt even try to boot.
4. Can you hear any Beeps when you try to turn on the computer. If yes, what is the sequence of those beeps.
If you answers are -
2. no image
3. only the satellite light is blue, the powercord is blue and the battery is blue
4. no noise
Please do the following carefully and let me know result : 1. Shutdown and Unplug your laptop. 2. Remove the battery from the laptop. 3. Wait 2-3 minutes 4. Now press ON (power button on laptop) for 1 minute 5. Then release the finger and wait one more minute. 6. Now plug in the power cable (dont insert battery yet) and press ON button. 7. Did your screen start working now ? (do you see windows loading)
You need to have the case's power switch plugged into the jumper pin header of the motherboard. Plug in the PSU into the 120 volt mains, enable the PSU via the switch (the one you turned on in the video) and then press the power switch on the computer CASE. That should do it!
plug it in, press power button (blue button on left) turn dial to desired cycle then press and hold the blue button on the right until u hear a click then relese. if it doesnt light up the display when u press power the washer is broken.
make sure you've got everything plugged in to the mother board, especially the cpu fan attached to the heat sink. it's possible it could also be a memory issue, pop out your memory modules and reseat them.
First remove the power plug from the smps and press the power switch few time and wait for few minutes the re plug the power connector to the smps and switch on the computer if you still dont have power then you will have to check whether the smps work to test that its not enough to test the voltage in the 21/24 pin you will have to short the green wire and the black wire and see whether the smps fan is working if the fan is not working then the problem is with smps
hello, I have a solution for u i think it may help for u. your problem is:
When u press the start button... the power LED comes on but there is
no POST beep or BIOS screen or boot up. The SMPS fan and Processor fans
also dont come on at all. there is a small LED next to the SMPS plug on
the motherboard that does light up when the system is connected to a
Part of the system configuration is the kind of PSU you have in your
SOLUTION IS So, what kind of PSU?
Try to borrow a known good PSU. Or better yet, see if you can test
your PSU in another working system. If you cannot do that, try to borrow
a DMM to measure the voltages. Yellow wires should be 12 volts. Red
wires: +5 volts, orange wires: +3.3 volts, blue wire : -12 volts,
violet wire: 5 volts always on. The gray wire is really important. It
should go from 0 to +5 volts when you turn the PSU on with the case
switch. CPU needs this signal to boot.
You can turn on the PSU by completely disconnecting the PSU and
using a paperclip or jumper wire to short the green wire to one of the
neighboring black wires.
This checks the PSU under no load conditions, so it is not
completely reliable. But if it can not pass this, it is dead.
Your unit has some sort
of PSU fault, or a problem that is shutting down the Power Supply
Unit, PSU. This happens so that no further damage, and possible fire will
occur. The sound is it starting up, shutting down, over and over. You need to take the unit to a reputable service
centre/man and ask for a firm "Quote" for the work to be done.
Just to check the voltages coming from the psu. However if your old psu is doing the same it must be something else. Did you try it without the graphics card? and is it the fan in teh psu which is spinning up?
My next port of call would be any other expansion cards, followed by the memory modules. Take them all out apart from one memory module and try to boot.
Also check that the pins from the power button are connected correctly. you can also try starting the pc by touching the two pins together with a metal tipped screw driver.
