AsRock K7S41 mobo and Athlon XP 3200+

[doncaosdelanada]

Hi
I am having a lot of trouble upgrading the CPU on my PC.
I have a AsRock K7S41 mobo and an Athlon XP 3200+.
Memory is 2 x Kingston 1GB PC3200 DDR RAM KVR400X64C3A/1G (just purchased as my other memory was wrong speed).
I have updated the BIOS to P2.60
I have set the FSB jumpers correctly.

When I boot up The CPU fan whirls for about 5 seconds and then that’s it.

Any ideas why?

All I wanted was a processor which supports Silverlight 3 and SSE (unlike my old Athlon processor)

TIA

1. If the power is on for a full 5 s, then shuts off, maybe overheating. Make sure that you have installed the heatsink / fan unit properly, so that it is level, oriented the right way, and in contact with the processor die. Follow the install instructions.

2. Try resetting the system BIOS.

3. Make sure the power supply is adequate to handle the increased power draw from the faster processor.

Is the heatsink compound properly applied?

[CPUShack]

no beeps?

I had a computer do that and turned out to be the power switch actually getting STUCK.

so would turn on, then turn off 4 seconds later

Dead cpu is the worst case scenario.

Not uncommon behaviour for a dead chip.

Thanks for your advice so far.
Can it really be overheating in less than 5 seconds? I will try to apply some new heatsink compound as soon as it comes in the post! (Damn post strike!)
I have switched it on and off many times.
I have reset the BIOS after upgrading to the latest version.
I'm wondering if the power supply could be the problem. This is the second time I've updated my computer but never changed the PSU. What watt power supply do I need and how can I find what I've got at the moment?
Many thanks

There should be a sticker on a side of the PSU with wattage.

If you have the board flat on a table, and keep the heatsink in place with your hand (so not attached as it should be), it should at least go through POST (where you see Ram counted), like 5-10 seconds.
Just a basic test. Working even without thermal compound (matter of seconds, not for a normal use).

If the heatsink is not totally touching the surface of the cpu, overheating occurs quite immediately as other users suggested.

Did this system have stability problems before you started the hardware upgrade?

If you install the old Athlon, does the system POST?

[doncaosdelanada]

I'll try holding the heatsink in place later. As of yesterday evening with the new CPU in, it wasn't POSTing.
The system was stable with the old CPU, memory, heatsink and CPU fan.
If I put the old CPU back in again (and set the FSB jumpers appropriately) but keep in the new memory, heatsink and fan, it seems to work ok for 45-60 mins then shuts down. I haven't yet tried putting the old heatsink and CPU fan back in with the old CPU.
Thanks again

With ols cpu in, go to bios and disable hybrid booster oveclocking utility "if" checked to work.

Maybe there is a failed overclock attempt. Just a guess.

PSU should be at least 300 W. 400W would be safe enough.

[doncaosdelanada]

Success! Of sorts,
I got the heatsink compound today and applying that has made a big difference.
PC now boots up and I get as far as logging into Windows and the PC either reboots or hangs.
Do I need to reinstall the OS (Win XP) or just some drivers - where should I start?
I can go into safe mode no problem. If I go into safe mode with networking the system does much the same. Guess it could be the network card drivers I need to reinstall.

BTW CPU is 300W
