PC stops during startup - power fan on - CPU fan stops.

[teebird]

Hi All My PC was working fine and then just starting doing this.

I will turn it on and it does through the startup sequence and show the windows splash screen and then it just stops. Stops as in the fan on the power pack is still going but the fan on the CPU stops. The disk light goes off but the power light remains on.

I have cleaned both fans and I have not installed any new software either. I am running Win XP Home.

Have you tried a new cpu fan? You don't say what the speed of your cpu is but I'd be very careful starting your PC up knowing the fan stops running as it can ruin your CPU and maybe already has.

It this isn't the issue, will your computer startup in safe mode?

Might also be CPU overheating, a bad connection between the HSF and CPU, the CPU has a thermal override. That said, the first place I look for issues like this is the power supply.

Can you check the cpu fan elsewhere/try another cpu fan (to eliminate or incriminate it).

If not as simple as that, I'd suspect PSU or motherboard (or possibly both now) - though the overheating possibility has to be there as well (like the first time it happened, cpu may just have got fried).

well ..there could be 2 reason...
1-your power supply
2-RAM

first remove the Ram and then insert into another slot and boot the system...
if its not work then borrow Power supply from your friend and change the power supply and check...i hope so it will work...

My bet is on the CPU HS FAN... if it stops, the CPU heats up and the protection circuitry cuts in and stops the Processor from overheating, if it is an older CPU without the protection then it may be fried...

so I would go with what Wulluf suggested and replace the HS FAN first, apply HS Compound (Artic Silver comes to mind, about pea size and spread evenly across the DIE or the metal cap that modern CPU's have now a days)...
