Ever since I replaced the graphics card in my Shuttle, the computer has been acting a little "odd".
Sometimes the hard drive will just power down. Windows will still continue to function, but doing anything that would require a program to access the hard-drive causes the spinning circle to be displayed. Most of the time it'll recover, but that could be anywhere from a couple of seconds to a couple of minutes. Once it blue-screened, but I didn't have mini-dumps enabled so I couldn't find out what the problem was.
In addition, sometimes the computer fails to boot up. It either gets stuck at the end of the animation (where the four colours come together), or it'll get past that to the login screen and when you've entered your password it'll then hang on the "Please wait" screen.
- Checked I'm running all the latest drivers for all components.
- Checked I'm up to date with Windows Updates.
- Checked for dislodged SATA cables.
- Swapped SATA cables with the DVD re-writer.
- Installed Acronis Drive Monitor and checked for S.M.A.R.T. errors - everything is within tolerance.
I've looked in the Event Viewer and there are a large number of ATAPI errors around the time these problems happen. They are all event code 11 ("The driver detected a controller error on \Device\Ide\IdePort1") which, although I've not found a foolproof way to double-check, I'm pretty sure it's my internal hard drive.
I have a horrible feeling that all of these problems are caused because my PSU is too underpowered for the computer. This would be annoying for the reason that Shuttle don't do more powerful PSUs, so it would be an expensive replacement.
Could it be a PSU power problem - or is there something else I could try?
