Computer can't boot - powers on, off, on again, hangs
Posted on 2009-04-29
Motherboard is a P5K SE
OS is Vista 64-bit
I opened up my pc case to remove 2 SATA 250GB hard drives (neither of them is the boot drive, which is a 1TB drive). Whilst doing so, I was wearing an anti-static wristband clipped to the pc case. When I closed up the case, I can no longer switch the computer on. What used to always happen is that the blue LED around the power switch would light up, I would get a system beep and then the computer would go into its normal boot sequence.
Immediately after closing up the case and switching the PC on, it lit up the blue power LED, did the normal system beep, went into the regular pre-boot sequence but hung at a black screen. After a few minutes of this, I pressed the power switch for 4 seconds (which powers off the PC) and then switched it back on again.
Ever since then, I get no blue LED, no system beep and the monitor won't even switch out of standby mode, with one exception. In order to see if the problem was with the switch on the front of the pc, I removed the front part of the PC case and pressed the power switch from there. The first time I did this, I got the blue LED, system beep and the beginning of the pre-boot sequence, but then went to black screen again. Since that one time, I continue to get no LED, no system beep, and monitor in standby mode - with the front part of the case on or off.
I've checked to see that power cables for the PC and monitor are correctly in. I've also checked that the front panel connectors to the motherboard are secured. The 2 remaining hard drives in the PC are connected to the SATA 1 chanel (boot drive) and SATA 2 channel (data drive).
I'm really not sure what's going on here. As far as I can see, the computer should boot up fine - but simply isn't.
