PC(desktop) won't power on!

[Kakashii]

computer spec:

• alien ware case, power supply came with it, has fan with blue.lights
• asus navidia dulex mother board
• amd athlon 64 processor 3200+
• nivdia 3600 GS video card
• 1x4 ddr dam!
• ata HD's

-----------------computer won't power on!


my friend had this system for about two years, or less before i bought it from him: he did replace some of the fans & the video card!

issue: today i tried to power on the computer and one i say some fan light came on then it just turned off! and comp won't power on again.

i shut the computer manually by holding the power botten all this week, so i did it about 6times. since my vista would get stuck at shut down i had no other option, some time how ever i pressed the reset button and as soon as it got to boot screen i powered it off, and that is what i did last!

old things that can be useful info:

• i just thought it was wired that some time when i un-intentionally move the PC, the fan (blue)light was acting wired(it dims adn comes back on, just two of them)! teh computer also made a notice like a paper cut after the OS got stuck at shutdown, and it also made it while in the OS while browsing and doing things on the computer!
• also i again had vista ULTIMATE installed after i got this pc from him a month ago, and it got corrupted like week later after i installed it! allot of program stopped working and now the wireless internet was not working on it, so i had to do manual shutdown allot! i was about to erase vista and put windows xp pro on it!

things i tested:

• unplugged teh hd's all of them including teh vista one!
• Unplug the computer for at least 1 minute. Then hold the power button in while you plug in the computer.

1. cpu fan, well there is one installed on top of it and it's connected same way as other fans! but i think it was not working, gonna try it in a MIN and reply agAIN!

2. motherboard has a yellow power light, and it's on, so the motherboard is not fry, nor is the power supply! as i think.

3. i don't know how to "reset cmos jumper," but i will Google it up! thanks

Hi Kakashii

First please don't touch the CMOS just yet, when you press the power button on your PC do you see LEDs light up on the front ?, can you remove the side panel so you can see the Motherboard ? do any of the fans spin, CPU fan ?, can you hear the hard drive spin up ? do you hear any Post beeps ? Asus navidia deluxe motherboard can you give me the number of this board as there are a few Asus deluxe boards

1. i see no lights open or no fans spinning what so ever, i have the computer side open and double checked that part!

2. no beeps at all! the only thing that is on is the motherboard power light, and my power supply does have a power button, which is obviously on the back!

3. mother board: A8N-SLI Deluxe socket 939

could power botton fry by chance too, how can i test that, sicne it's power source coming from teh motherboard, i think!

important: there is no pin in CLRTC, to clear cmos, i mean there is not even pin in defuilt postation, can that be a problem, and wherer can i buy the pin. also i do have some ATA hd black pins that are used to set it to master and slave can be used , not sure if it will fit!

thank you

Hi Kakashii

Just been looking at your Motherboard and the CMOS battery and CMOS reset jumper are located just to the right of the lower 2 USB 2.0 headers, and i would only use the proper jumper, you may be able to get one from stores like Maplin, as for you Power supply (PSU) disconnect the Motherboard cable and see if an optical drive tray will open ?

[Kakashii]

first is it really bad for not having CLRTC jumper pin! there, i am gonna try to remove the battery to reset teh jumber will remove it for a hour, but i guess you only need to switch the CLRTC pin if you only want to clear the CMOS!

"as for you Power supply (PSU) disconnect the Motherboard cable and see if an optical drive tray will open ?"

secondly and last thing: waht you mean by above, you mean diconnect teh power to teh motherboard and try to see if my cd/dvd rom will get power or not! right!

thanks for your reply! lol

unplug the power to the motherboard, the cd/dvd drives should still get power from the psu to open and close if not then the psu is the problem.
i usually go through each item until i find the faulty part
psu,mem,graphics card etc

[Kakashii]

well i did what you told me to do and i got no power on cd/dvd rom drive, but still got power on motherboard, since one light on the motherboard is on when i plug in the power, and idea why! the current PSU is 600Waats!

questions:

• so what brand would you recommend! and why you think my PSU died, is there could be a cause, it's only an year and a half old. gonna try to see if it's still under waranity!

• but still confuse about the light on the MBoard!

• why did my fan light go a little dim, when i accidentally shock or touched the desktop case! because if the case(tower) has a problem too, i will try to get a new one that comes with new power supply!

• my friend only used half of the screws to attach the Mboard to case! does that matter! could that be something too!

can you try to please answer all my question on this post, since some of these question were never answered before, i reposted them twice,thanks allot for your help.

flickering lights could be down to the psu being faulty.
good psu makers Antec, Tagen, Enermax, OCZ etc
before you buy 1 though see if you can borrow 1 just to make sure thats the problem.
just because a psu has a high watt rating doesn't mean it can handle well under load so the better the quality the less likely to fail better voltage rails etc.
i alway try to buy the best i can, you get what you pay for usually become true at some point
don't just buy 1 take time to read up on the good ones and find out the pros and cons.
a good psu can last for years the low quality ones usually a lot less

the light on the mb could still be powered by the psu even if it is faulty it won't need much to power it , even after disconnecting power some leds stay on for some time

thanks for all teh info, i was gonna buy a new tower, and most have power supply that comes with it! i have another pc that has a 200w power, i will test it later today or tomorrow with that to make sure everything, i will post the results, thanks


also you forgot few question i had:

• my friend only used half of the screws to attach the Mboard to case! does that matter! could that be something too!
• also i only installed vista ultimate and vmware on top of that with xp pro on this PC after i purchased it, and it was courted like one week after i installed that, i haven't put another Os on it! but wanted to know why that happened! could power supply caused that installation of OS to go bad, plus it wouldn't pick up some of my PCI slot! like my extended ATA adapter and tv tuner! and sometime it did pick it up put had problem installing the drivers! so i was just wounding about that! i thought it was only because of vista!

thanks for all the reply today lol!

a 200 watt psu probably won't be enough for that system i'd try something higher, you don't want to kill the rest of the stuff also the 200watt might not even have the right power connections for the board.
a faulty psu can cause lock ups with windows etc before they eventually fail
i wouldn't use vista myself yet due to lack of driver support
that and i've only just recently installed xp after years of win2k
as for the screws on the mb well i never use em all just enough to make sure the board is secure
