    I have the same problem as Steve. How do I check if the POST was completed. When I turn on the PC I the pc fan and Hard drive spinning, however what can I use as an indicator to check the completion of POST. My issue started after blowing off the thermal compound for from the intel chip. Is it possible that a short occurred? I followed the above steps, but no success! Please help, I need a computer.

    Hope to hear from you soon. Thanks in advance for your time.

The best advice I can give you is to remove the motherboard battery (UNPLUG THE PSU BEFORE YOU WORK ON THE MOTHERBOARD) and let the system sit for about an hour. If the CMOS settings are corrupted, removing the battery will erase the corrupted data in the CMOS, which will automatically reset the CMOS to the default settings... Then, plug the battery back into the motherboard, and try to boot the system...

If that doesn't work, you should disconnect EVERYTHING attached to the PSU, and remove ALL of the add-in cards (modem, NIC, soundcard, TV tuner, whatever you have), and install ONLY the CPU, the heatsink/fan (don't forget to PLUG THE CPU FAN IN), ONE stick of RAM... you get the idea. DISCONNECT the HDD, the FDD, the optical drive, and ANYTHING ELSE from the PSU. When you're ready to test the system, you should have ONLY the CPU, the HSF, and one DIMM plugged into the motherboard. Attach the PSU connectors (both the main ATX connector AND the auxiliary 4-pin 12-volt connector) to the motherboard, and try to boot the system. If it works, SHUT DOWN and UNPLUG THE PSU; then install ONE component (the floppy drive, for example), reattach the PSU, and reboot the system. If the system POSTs, shut down, unplug, and add another device. If the system does NOT complete the POST process, the last piece of hardware you installed is probably the culprit.

Take your time with this; be methodical, and make GOOD notes about the steps you've followed, so we can help you work through this problem...

Best of luck to you; keep us "posted" on your progress...

    Forgot to mention that you need to install the videocard, if the motherboard does not have an onboard videochip... Sorry about that; I was talking on the phone helping my nephew troubleshoot a computer problem while I was typing my original reply to you...

T6528, when trying to power up, no video, no beeps, cpu and case fan run at full speed. Tried removing memory, no beep at startup. PC was working fine before, and fans only came on when necessary. Some...

If there was a video error generally you would get beeps that are similar to removing the memory.
when this happens you are looking at a failed CPU or Motherboard. For the system to get to the POST it has to get past the CPU hence you have no beeps.

First thing would be to clear the bios and cmos. use the jumper and remove the battery.
If clearing does not work then you would remove the cpu, turn the system on, then off. then reseat the cpu and try it again (remember heatsink as well never turn a system on without the heatsink on it)

No post to bios on new pc build

FIRST....... Make sure you remove the stock thermal compund (pasty/sticky stuff) from the bottom of the heat sink as well as from the top of the cpu.........

Second APPLY some ARCTIC SILVER 5 compound-ust a thin coat of it over the top of the cpu......use an old credit card.....keep it ff the sides and bottom's important not to use too little tube will do anywhere from 3 to 5 CPUs...!!!
(stock thermal paste/thermal compunds......**** BADLY and can cause a cpu to burn up)

reseat (properly) the cpu and carefull

Now make sure you're 24 pin or 20+4Pin Power connectors are connected, as well as your fans..........disconnect all your SATA Devices, and remove everything but the video card , CPU, and fans.......Now it should post (if all your jumpers are set correctly...........

IF it still doesn't post, remove the video card and reboot.

If it doesn't beep at all......... You have one of 2 things.........A DEAD CPU, or a DEAD MOBO

Pc Seems to be dead wont load bios post moust doesnt work or keyboard or monitor

I have the same problem, the CPU fan spins, keyboard lights blink, no start up screen, or bios.
But, when I push a few times on the pc reset button, then the CPU fan is becoming still, the keyboard light are out and I can start the computer again in a normal way.
Can this one be a temporally solution for you too? Do you have any suggestion about?
I guess it can be an electricity dysfunction of a wrong fixed cable.

Tried to turn it on, no powr. Replaced the power supply, little led on the mother board, but no power, no fans.

I tried 3 different power supplies.
I stripped out the memory and hard drive and put it in the dumpster where it belonged.

Sounds like mb is not posting,
remove all cables to drives,
remove all cards except video , re-seat video.
remove all external devices keyboard,mouse , usb etc...
remove all but one stick of memory
re-seat the cpu
power up and if fans all turn and still no post then power down, clear bios jumper , swap memory
if fans turn and still no post pull memory ,power up does it beep,
if it does memory may be blown.
swap video card or cpu
at some point you wont be able to swap much without extra parts or help.

You should only hear 1 beep. That 1 beep is power on self test, known as P.O.S.T.
That loud flat line sound (And I'm pretty sure about this), was you're CPU. Just because you ran & passed the stressed test is nothing compared to running the system under load? That's why when you put in you other memory nothing changed. If you hadn’t mentioned you clocked up the FSB I would have come to the same conclusion hearing the loud flat line statement.
Can you test the CPU in another board? That is about the only way to be sure it's not the CPU. Memory does not make that kind of sound. Memory makes short & long beeps.
You can try clearing the cmos/bios by going to pg. 2-18 in you're user manual. This will reset the bios back to default settings & cross you're fingers!

If I can be of more service, just post back & let me know how thing go.

Good Luck!

No post, only motherboard light on, green.

Hey there aj1253, It seems you are getting power to the board. are the fans running?Are you using onboard video or video card. Onboard is suggested for test. I would also suggest you reseat your ram. That is removing it and ensuring it seats properly. Beyond that I would ask you provide more info ( ie is this a new build, or did it just stop working, configuration details, model #'s, et....)
