that usually means wrong or bad ram, bad cpu or bad psu

with an unstable computer the fans will still run but if thats it I would check the ram

oh yea a dying mobo can act just like that

ok I hope this helps some but Im goin to bed know

later

hey joytech this issue is keeping me up

this didnt click till now, in an earlier post you were able to get the computer on with the hard drive disconected, so maybe you do have a good mobo.

ok start from the begining and document everything you do so you know what you have tried and not tried.

1. disconect everything
2.install your fans, ram, and if you have video on the mobo use that, if not install the video card.
3. connect the monitor
4. turn the computer on
does it work, turn it off and on serveral times make sure,
5. assuming the computer works go into BIOS and set the defaults and save the changes
6. now connect the hard drive if you are using a 40pin IDE cable make sure that the red strip is facing pin 1 on the drive and the mobo, make sure the jumpers are set correctly on the drive make sure you have the correct end of the cable connected to the mobo and to the drive.
there are several pictures all over the internet if you need help with that.

7. if you are sure that everything is correct at this point and the computer does not boot then there are several options to take from this point.
a. the drive is bad, replace it
b. the MBR is corrupt, fix it
c. one of the files needed to boot windows is corrupt, copy new files from cd.
8.if you can boot from a cd then it might be possible to fix

you could repair the MBR by running the FIXMBR command from the recovery console

or you could try to copy some of the start up files from the cd to the drive such as NTLDR

to verify that the mobo is good swap the drive with a known good drive with an operating system on it if you have one if the computer boots then you know for sure the mobo is good, if it does not boot then the disk controller might be bad and you will need a new mobo

this all I can think of for now, follow that step by step let me know what happens.

off to bed for sure

please help me. i have had my computer for just over a year now and when i went to turn on my computer after school, its fans went to max rpm and only no input signal appeared. then after a few attempts to reboot, it was working again. but it's doing this every time i try to restart or turn on after shutting down.

i know its not a PSU problem because i replaced it with a 300W one that came with my pc. (took out the 8800 first of course)

also these problems started when my pc would not allow me to use a PCI-E card like my 8800 anymore it just started using onboard

here are my specs, (what i know)

Mobo: some sort of ASUS AM2 CPU: AMD Athlon X2 +5200 Dual-Core (2.7GHz each core) Graphics: Nvidia GeForce 800GTS BFG OC PSU: Codegen 530W HDD: 2 IDE hard drives (80GB) (40GB) RAM: 1.7GB 600MHz OS: Windows XP Home edition x32 Fans: 2

I personally think this might be either a POST, CMOS or motherboard error but no error beeps are excreted by the internal speaker.

if you like, i will be on MSN most of the time and will be listening to any suggestions

thank you for the help, i shall try the RAM swapping. but theres a problem, i forgot to list i have 3 512MB sticks and a single 256MB stick.

and that i have had these RAM stick's at minimum for 8 months

AND its hard to start the pc at all because 70% of the time it doesn't POST. just displays no input signal as soon as i go to turn it on, the above post tells of the fans at max RPM until i restart it enough times in order for it to POST and boot up, one mistake i made was with my AMD Athlon X2 +5200 (2.7GHz each core) i forgot to plug in the fan. but it works out well because im using the same CPU to post this message.

by the way... Safemode shall not prevail in a hardware error ='-S

wow didnt realize you posted again until i checked my mail a few hours later. i tried all of the above, the same happens even when no hardware is connected, just the basics to ensure proper functionality to enter the bios. i even replaced one ram stick at a time, paired them, had one in at a time ect... im starting to asume a dead mobo. bad news for me as it might take a few weeks to get.

base on the issue i have highlighted in red, those are the items you need to pay close attention to.
first are all the ram stick the same clock speed and compatible with each other.
next are you using 300W PSu or 530W. what PCI-e card do you have attached to the pc.

remove the ram stick, clean each and user Only the 256 to boot the pc. then shut down and do the same for ONE of the 512. (Remove the 256 first) next verify you PCI-3 is getting enough power. if you remove all item and start up bare bone then the problem points to you MObo. let us know what happened

ok joytech

now we have established that your computer will not work with just the essentials

your next step should be to take all the ram out and install them back one at a time. so install just one stick and turn the computer on.

does it work?

if not that stick could be bad try another one.

if it did work leave it in and install one more and then turn the computer on.

repeate this process to identify if you have bad ram

if the computer still does not work after that the only thing left is the mobo it will need to be replaced

yeah dust will kill a mobo. well if you are positive that the ram is good then it has to be the mobo. best of luck

dust can conduct electricity, and it could be possible that is why your mobo is acting like that, but at the same time it doesnt take much to damage a mobo so even if you clean it you still might have the same problems if the mobo has been damaged
