Problem with random powering-off and continuous beeping
I have a new PC, built by a computer shop. It has been working great, but recently, without any apparent reason or warning, it seems to power down. There is nothing on the screen, the power light is on, the hard-disk indicator light is on, and the computer tower makes a beeping sound. This sound is a long beep, every 4 seconds, which seems to keep going until the power button is held long enough to turn the PC off.
The PC specs are as follows;
Mother board - ECS C51GM-M S AM2 MATX DDR2 S/L/V
Processor - AMD ATHLON 64 3500+ 512K SKT-AM2
Memory - 2x 1Gb DDR2 533 CL3.0 16 CHIP
Hard disks - 1x Hitachi T7K250 200Gb ATA133 7200rpm 8MB Cache
1x Maxtor 6L160P0 Diamondmax 10 160Gb 7200rpm ATA/133 8MB Cache
Graphics - Asus X1600 PRO 512MB DDR2 / 128bit
CD drive - Samsung 52X32X52 OEM CD REWRITER
DVD drive - DVD±RW NEC ND-3540 16x Double Layer
3.5 Floppy Drive
MIDI Case ATX-900 300W
The computer shop have not encountered this before so cannot provide much help. There seems to be no loose wires or connectors. There also seems to be no pattern as to when or why it turns off, it happens randomly. Different things I have been doing when it has gone off include when Im editing videos, playing games or simply copying files to different folders.
Can anyone help with this problem?
