Hi,

My Dell Inspiron 530 desktop has started to boot differently.

When I press the button to start on the front the fan kicks in on full for a short burst then stops, it repeats this sequence then boots as normal.

Possibly unrelated, but before this started happening I had a problem with my monitor. It was blank after I booted. I needed to check the cable connecting to the monitor but wanted the power off first before I started messing with the connections. I performed a forced shutdown using the button on the front. After reattaching the cable I rebooted and the monitor was fine. However, now the computer boots as described above.

Again possibly unrelated, the system froze today and I had not force shut down with the button on the front.

I just performed the Extended Test Dell Diagnostics (F12) and everything passed OK.

I have run Windows system restore to an earlier point and have the newest BIOS.

thanks for you time,

J.

OK,

I think that the problem might be solved. I will see over the next few days.

The monitor went blank again so I tried using a VGA cable to connect instead of the DVI one. Everything now works fine. It boots normally and no problems with the monitor. My guess is that the either DVI cable is broken or the DVI port is. I don't understand how this would result in the change in behaviour of the fans on boot though.

If it continues to work with the VGA then I won't buy a replacement DVI cable. Will be keeping an eye on the system to see if its all OK now in the longterm.

:)
