PLEASE SUPPLY RELEVANT INFORMATION:
Operating System Version:
Problem Application Name & Version:
Problem Hardware Make & Model:
Error Messages:


I have just completed bui;ding a PC. After only a few hours use, the CPU fan started to whine loudly. Following shutdown, I reseated the fan. Power on resulted in an electrical fizz sound and a "pop" and the fan never started up.
The PC continued to boot up, but with an alarm sounding. Presumably BIOS related telling me the fan was not working. I switched off the PC so didn't notice if any error messages were displayed.
My motherboard is a Gigabyte 81915P Duo (Pro) with an Intel P4 530 LGA775 processor and Intel fan. Both items have today been returned to the supplier for replacement.
I am curious to know as to what "popped" when I powered up the PC after moving the fan, hence the question on fuses. And will things be OK when the replacement parts are fitted?
Thanks for anyone's input to this.

Was the Heatsink,Fan and CPU seated properly?
There are no fuses...the sound you heard could have been the Fan itself or the CPU.
Have you heard back from your supplier yet?

The only fuse I can think of would be in the PSU (Power Suuply Unit) but if that had blown then the computer would have gone off straight away. More than likely the problem would be with the heatsink or CPU. The alarm you heard probably would have been the overheating alarm, because the fan wasn't operating.

Thanks to Cactus and KaTaLyst for your feedback.

At least I now know that fuses aren't an issue.
I believe that the original fan was seated correctly, as the paste on the heatsink base and transferred across onto the CPU's surface. And the fan's 4 plugs (what useless plastic screws these are) were solidly attached. I can only assume that the wiring must have been faulty.
Fan and CPU returned Wednesday, now waiting for replacements to arrive.
Again, thanks for your comments. Hopefully the PC will be up and running soon.

Update, it's not good.

Fitted the new cpu and fan this morning. Switched on, the PC started to boot, the alarm started (it is a BIOS fan not working alarm, I checked the BIOS settings as the PC started up) but the fan didn't start working. Waited a few moments watching the CPU temperature but no fan, WIN XP loaded OK. Switched off.
Conclusion... it must be a fault in the motherboard. The original fan must have blown part of the circuit somewhere.
Any views?

I have now replaced the mobo and everything has been working OK for 2-3 weeks. Until another noise started up last week. In addition, the case surrounding the PSU, especially around the exhaust fan, is very warm, almost hot, to touch. Everything's OK when started up and idle, but after one hour so of game playing, a high pitch whine begins followed shortly afterwards by a noise similar to marbles rattling in a bag (could be fan blades catching on something). These noises seem to be coming from (I think) the PSU fans.
I have taken the lid of the computer case and this seems to keep things cooler and the "marbles noise" at bay. The high pitch whine remains. But this is not the answer.
I have checked the cpu temperature in BIOS (it reaches 53 degrees Centigrade max) and the CPU fan seems to be working OK.
Any ideas anyone?

Firstly I would download a BIOS update from the motherboard maunfacturers website then I would download a motherboard monitoring program from the "test software" thread in the forum. Use the program to find the temperature of the CPU as the BIOS isn't usually very acturate when it comes to temperatures. I would then download "Prime 95",this program is used to stress test your CPU, it will put your CPU up to full load(100%). Now check the temperature in the monitoring program.

I would try to listen for where the "marbles" sound is coming from, it's possible that the bearings are gone in one of your fans and this is what is responsible for that sound.

Check it out and let us know how you get on.

Update... Problems met downloading the BIOS update and test software, so nothing to report on this suggestion.

So decided to change the PSU and Intel CPU fan. Installed an Akasa fan and a 350W PSU from a new PC case (I was going to reinstall everything into this case but the front panel cables etc. didn't match the Gigabyte motherboard layout/pin settings and colour coding). Seemed easier to just swap the PSU's over in case the fan noise problem was PSU related.

Result, no whine or "rattling marbles" noise (so far) from a fan, but the PC case surrounding the PSU still gets quite warm. BIOS temperature and fan alarms are enabled, no alarms sounding as yet.

That's good anyway. The case shouldn't really get warm though. Is there a lot of stuff packed into a small case?

A good indicator as to whether the CPU is too hot is to touch the metal part of your heatsink that sits just above your CPU, if the metal is too hot to touch then the CPU is too hot.

What problems did you have downloading the BIOS update etc.?
