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.

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

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

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
