Have just finished new PC build. Have been running the PC for approx 6 hrs (just in BIOS) checking temperatures. Everthing was good, all working, temperatures ok. Have run it a few times on different days and good everytime. Today however I turn it on planning to install windows and the internal speaker gave it's usual single Bios beep. But this time it was quickly followed by a continuous high pitched beep that doesn't stop.
I have taken out RAM + tried different combinations with it.
Removed grahics card, still no change.
even with this speaker noise the PC boots with correct post screen and reached Bios.
Case = Antec 900
Motherboard = GA-P35-DS3R
CPU = Q6600 with Freezer Pro 7 cooler
RAM = 2GB Ram 667MHZ (Kingston)
PSU = 620W Corsair
GPU = 320MB Geforce 8800 GTS superclocked
Harddrive = two Wester Digital SATA2 250GB (WD250AAKS)
DVD = two Samsung SH-S203B DVDRW
Motherboard + CPU + RAM = 1 short beep then 2 short (closer together), then continuous
Motherboard + CPU + RAM + Video Card = 2 short (different tones) then continuous
Motherboard + CPU + RAM + Video Card + Hard Drive = Continuous interupted by 1 short then continuous again
Well that seems to work. The continuous tone is still there at startup but disapears after the first post beep. Its a little annoying though, as the fan now runs at maximum all the time. "Auto" is even the default and that causes the problem too. Strange that it was ok when I first changed the settings.
