Hi,

When I turn on the PC all the fans come on and it boots into windows without a problem. Then a few seconds after getting into windows the Power Supply Unit and rear fans stop working at the same time. As do the blue neons that are on them. The rear fan is connected to the PSU for power and has no fan speed control.

I would have thought its the Power Supply Unit at fault as all the other fans are connected to the motherboard and not directly to the PSU. Although I would have thought if the PSU was at fault they wouldn't come on in the first place.

PC specs are as follows.

CASE: Thermaltake Soprano
Power Supply Unit: Jeantech Storm 700W
Motherboard: ASUS PK5
CPU: Intel dual core 1.8ghz
GRAPHICS: MSI 7900 GTO
Hard drive: Samsung spin point 500gb

Thanks for any help,

Kyle.

Update.

Now the front fan has decided not to work. This is connected directly to the motherboard. Could it be something to do with the BIOS. I'm now very confused.
