Hi, I bought an optiplex 3040 Small form factor machine running win7 initially but I restored windows 10 on it. i've had it only 2 days now, but I have detected two problems alarming - I'm trying to find information on whether they are common problems with this model or I have a faulty unit:
1) I have a USB2.0 3.5" HDD dock (with its own power supply) that when connected on any USB port and whaving any HD docked, after a couple minutes will start disconnecting and reconnecting in rapid succession. On other computers the dock is running rock solid stable. I'd worry that it might be my particular 3040, but I've read that Windows 8.1/10 has this issue. The event viewer doesn't show anything abnormal, other than a warning with ID 51: An error was detected on device \Device\Harddisk1\DRx during a paging operation.
Anybody who could comment on that?
2) I realized that if I try re-connecting the HDMI plug while the machine is on (eg disconnect it and then reconnect it), it will cause the system to instantly reboot - this is reproducible inside windows, inside the bios or while memtest86 is running (booting from a USB thumb). I'm driving a VGA monitor with a small belkin VGA-to-HDMI adapter, and the problem will appear even if the VGA cable is not connected at the other end of the adapter.
My guess is that the HDMI plug when inserted short-circuits the machine. While this is not a huge problem (I could make sure to shutdown the computer before unplugin/plugging in a monitor) it makes me wonder if my machine is faulty and I should have it replaced/fixed, or if this is a fault with all optiplex 3040 SFF units.
Your personal experience and feedback regarding these issues would be greatly appreciated!
Thank you
