Try to unplug unnecessary hardware.. just plug in the monitor to video card, power, and the memory.. unplug the IDE cable or SATA and also the USB devices... Observe if your system will boot. sometimes hardware damages prevent your system to boot..

HP P4SD, its running good with 4 gb RAM, P4 3.0ghz, and a couple sata hd. The problem is the fan output voltage, i havent been able to read the output chassis and cpu cooler pins voltage cause i can find...


"i can find my dmm?" did you mean CAN'T?
"its clearly off", what is off?
the fans are 3 pins,2 are power, one is RPM tachometer.
"it all works fine", so you can boot and run any OS, ?

"the voltage reads +12vdc", where, at fan or PSU?
the fans run off 12vdc, they are DC motors (from outside fan)
if the fan runs slow at 12vdc the the fan is bad or is a low RPM
fan, as some are, bigger fans run slow, for less noise.!

first is the CPU fan it must run full speed, if not the CPU will overheat in seconds and ALL CPU shut them selves (by there selves) this way. so CPU fan is first. what does it do... there....?

then BIOS screens. GOT BIOS UP? and running? with, ESC key pressed>.
let me guess your symptoms
1: PC dead. will not boot.
2: BIOS dead.
3: all fans DEAD,.
4: power switch works and all PSU voltages read right, (seems not)/?
5: if the PSU power wire reads right(DMM), matching the side sticker voltages, and the CPU is dead, the MOBO is dead, or CPU is toasted.


here is a modern PSU, sticker.
see 5 to 10 power lines, see them. all must read correctly
if a fan is dead, then its dead if 12vdc is present on the fan power pins.

After power on Fans are running but no Videosignal, no bios startup.


Could be 3 things Memory or CPU or Powersupply. are you getting any beeps if so how many, how long. try taking all the memory out and powering up see if it beeps if so try to put one stick of memory in at a time and see if it will boot. if you get no beeps with memory out check powersupply some PS's have a red switch on back for current input. switch back and fourth about 20 times uning a pen and set it to the right current for you location. put ram back in see if it will boot if not its trial and error of the PS and the CPU replacement and it still could be the RAM giving false readings. yea i know sounds like a ball of fun.

Fails to boot, fans and lights on, no bios or anything


My recommendations would be to remove all connections to the board.
Remove the CMOS battery.
Remove the CPU fan and CPU.
Look at the top of the CPU, if you have a crust over the top of the CPU, you will need to remove it to a clean surface.
Next, your CPU fan should be a 3 wire connection on the motherboard, within two inchs of the CPU holder.
After cleaning the CPU, re-inseart and apply a heat sink lub for good heat transfer.
Re-install CPU fan and plug in to board connection.
Re-install your CMOS battery and power up unit.

With the CMOS battery removed, the time and date will need to be reset.
Also, in the BIOS for that board, you should be able to see temps. and rpm readings. ??
Hope the CPU has not taken a dump on you.!
Before you plug in the drives and other devices, check temps. rpm and voltages.
Have fun, hope this has helped you.

Bios unknow flash type doesn't find A drive or hdd


hi...!!!

If you have a PM-599LMR (M599LMR) motherboard or PG-5517A PreSystem you may not be able to update your BIOS. A batch of BIOS chips used on these motherboards was accidentally WRITE-PROTECTED when it was originally programmed. Any attempts to update the BIOS on one of these write-protected BIOS chips will cause the system to become unusable. The only way to restore your computer is with the original BIOS and the BIOS recovery procedure above.

Your CPU may have a problem


Have you removed all memory, other cards and unhooked all other drives to see if a short exists there? With a 300W PS some other component may be pulling too much that the CPU can't start so it tells you the problem is with the CPU or The CPU its refering to is on the video card? Good Luck, Tim

Monitor not Running(shows only orange light)


Unplug everything from the motherboard leaving only processor, fan and memory and try to boot up. It will take you to bios screen halt after looking for boot device. If it uses a video card, make sure video card is properly inserted. Then start plugging in hard drive and other devices if system comes up.

Your computer has memory problems. First check the video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM's. Reseat them and reboot. If this doesn't do it, the memory chips may be bad or they are mismatched .The CAS latency has to be the same and compatible with your M/B. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard.
