Page 1 of Help PC won`t reach POST

My brother`s PC gives error (on bootup) "CPU fan not working" and instead of the POST bleep, I get continious clips...

Fan is working and have tried a new one (just on case the old one was running slow).

Any ideas?

Don`t talk to me about PCs failing to POST - exactly what I`ve got on my Staples Xmas bargain - mind you, twas me own fault for inserting the CPU upside down and pressing ON I s`pose, when I changed the heatsink and fan :0

I wonder whether your motherboard is an Asus KV8 model ? This is a common problem with a run of Asus boards (some sold by eBuyer), which ends up being a catch 22 : you need to update the BIOS chip on the PC, but you can`t do that as the PC won`t progress beyond POST - the only way to rectify this is either to RMA the faulty board, or send the BIOS chip off to Asus and get them to send a new one.

Actually, your PC is reaching POST (power on self-test), what it isn`t doing is loading the BIOS, as the POST identifies there is a problem.

The most common cause for errors of this type (believe me, I know this as I have researched it thoroughly - stuck the replacement CPU in and still can`t post) are :

- check the memory is installed correctly - it could have wiggled loose (try removing one strip if you have two)
- problem with the video card - check this is installed properly
- the CPU may not have full contact with the heatsink and is thus overheating : luckily for you, the BIOS has a built in temperature sensor, protecting the CPU from overheating any further, and thus results in obscure error messages
- the PSU is on its way out
- the motherboard is FUBAR

Do you get any beeping noises from the PC ? Quite often these beeps mean something and can assist troubleshooting - need to know what BIOS you use - eg Phoenix, Award, etc

Something must have happened for this error message to appear- was there any hardware changes made ?

Hi Clayts, glad to hear your an expert in POST ;)

blips at maybe 3 to 5 per sec

the fan/heatsink are seated flush to cpu

I suspect that this is f**ked




As for the pc, the memory/cpu/graphic cards have all been removed cleaned and reseated.

Hi

I would find out the motherboard maker and have a look at the site for any problems and fixes for the model you / or brother have.


bye

R.B

See if you can work out here which beep code relates to your situation

Or there is a very nice man in Holland www.flashbios.org/ that will flash your Bios chip with your chosen bios file for the grand total of €10.

I can confirm its the mother board (by substitution)....

Thanks for the advice all.
