My HTPC won't post. It wont even show the video card screen


It almost immediately makes a high pitched warbling sound reminiscent of an english police car that stops temporarily when it seems to poll the DVD player


Configuration


Asus p4b533

H3D

radeon 9700

Delta 410

etc


I removed all cards except the video and it still won't post.


All the fans work.



??????????????????????


Has anyone ever heard this sound from a PC before? I sure haven't!!!

Did you try unseating the video card and reseating it?

The newer ASUS MBs have a " built in extended diagnostics" program

that can be used to determine if the MB or CPU or memory is faulty.

Part of that test can result in a "british police car siren" type

wailing sound if the CPU is bad. The sound you describe may be that

sound. Fortunately, it is easy to check and make sure, if you

wish.


If you want to use the built in ASUS extended diagnostics routine on

a newer MB / CPU follow this procedure:


Pull ALL of the PCI / ISA cards, remove all memory and disconnect

any USB cables.


The only items you should leave connected to the MB are:


a. small internal speaker (case speaker)

b. power supply cable from the power supply to the MB

c. case switch wire from on/off switch to MB


Now power up the MB.


a. CONSTANT BEEP = CPU and MB are both OK. Replace the memory and a

different beep will sound. That means you have a memory problem.

Swap to solve.


b. NO SOUND. = Bad CPU or Bad MB. To find which:

1. Remove the CPU and Power up.


a. British Police Car Siren (high / low) = BAD CPU

It can take a moment or two for this sound to start.


b. Silence = MB is bad, CPU is OK.


Good Luck

fan/heatsink problem? Some boards have an over heat indicator so you dont burn up the CPU. On ABITs its really loud. touch the cpu/heatsink to see. These newer processors take just a few seconds to overheat.

TiminMem,


I had some trouble with my MSI board (still do) shortly after I got it and it wouldn't post, can't remember if it beeped or not but I had previously cleared the CMOS with the jumper and when I replaced the jumper I missed on of the pins so it wasn't shorting anything (should have been shorting the upper two was only on the topmost pin) so the board acted like it was dead. That was my brain-donor move of the week.


Hope that helps (not that I hope you did something stupid but it would really suck if one of your components was dead).

I have seen this problem before last year! I posted here about it looking for help. Basically I think it has something to do witht he cold though I could be wrong cause it only seems to happen in the winter. Just happened again a few days ago.


What I wind up doing when it exhibits these symtems is I leave it on like that for 10 seconds or so till the noise starts to die down and then turn it off and back on again. Sometimes I have ot do it a few times, but it eventaully turns on.
