When I turn on my PC the fans come on as normal but it wont even POST.
I can hear a short noise from the cd just after I turn on, then nothing.
It does this for anything between 5 and 50 tries, until it suddenly decides to work.
I have tried different ram, video card, and tried them in another machine, they work.
The only difference I can notice now, as opposed to when it worked ok, is that the power unit seems to run almost silently, [more quiet than before], but the fan turns and so does the fan on the CPU
I really don’t kow, does anyone have any thoughts.









Desperately need some advice / Kevin

When it does POST [eventually]
I manage to get to post by double pressing the reboot button on the case
When it works, it seems to work in batches, ie it will reboot using above method, 8 or 10 times, then stops rebooting.
[Sometimes the Bios opens with message "Failed to boot 2 times, enter Bios F2 or Defaults will be automatically loaded in x secods]
When it does reboot, the first time it has difficulty opening W2K and usually takes 2 or 3 attempts before it gets there.
I have run chkdsk /r
Scheduled for reboot
It gets as far as checking the free space
Completes
and hangs on that screen
Reboot
Sometimes it will go back into chkdsk, sometimes it will go to boot
Sometimes it makes it

I am going crazy here
It appears that everything WILL work, sometimes
In my mind, I keep thinking I have a BIOS problem
but it must be more than that, because most of the time I am not getting to POST
Then I think it might be a Power Problem, but both the Fans are working [and I can hear it accessing (almost sure, the CD Drive[this is when I double click the reboot button])
so I think there is power
Then I go to memory
I have swapped similar memory from a known working good machine
[same ram ddr 400]
and the ram also works in the other machine
so I think my memory is OK
I also tried memory in the other slot in case there was something wrong with the slot
I swapped the graphic card for one known to work
[When it boots up, the old graphics card showed no problems
so I think the Card is ok
I have removed all other PCI Cards

WHAT ELSE IS THEIR?

WHAT ELSE IS THEIR TO CHECK?

How can I proceed

All Help greatly received
