PC Slow to load OS, but runs fine after.

Specs: Ubuntu 10.10 64-bit, E5200/4GB
I've been having a nightmare with my PC for the last week or so. It all started with Windows Explorer crashing every time I tried to open a window, but most programs ran fine. My DVD drive refused to work too. It became increasingly worse over the next day or so. I ran through all the usual checks; first I virus scanned from Windows, then I scanned from my Ubuntu partition, and everything came up clean. I defragged, cleaned up, unplugged all drives, ran in safe mode, problems still there. Next, memtest, chkdsk, and fsck, and apparently everything was fine. I got increasing more annoyed, so I formatted and attempted to clean install everything from a Vista disk I had lying about. Unfortunately after the install, which worked fine, i realised it was the 32-bit version, and I only have a product key for 64-bit.

I formatted again, and just installed Ubuntu. From this, I downloaded the correct ISO, which I've had trouble installing (but this may be due to a corrupt torrent or bad burn), but my main concern is as follows:

Ubuntu 10.10 64-bit is very slow to load, something that I never experienced before the initial problem started. I am confounded as to the cause of this problem, but I am now convinced that it is a hardware issues. It takes approximately 3 minutes from powering on to Ubuntu loading, and for this duration, I am faced with a black screen with a blinking cursor in the top left, this appears to be some kind of command prompt, as I am able to type on it. Before all these problems started, the boot time to Ubuntu was approximately 25 seconds.

What faults could be causing this problem?

To start with, why are you getting Ubuntu from the torrents rather than the Ubuntu site?

http://www.ubuntu.com/desktop/get-u...

Have you checked for overheating...maybe your CPU is throttling?

A key is a key for either version.

You can press escape key and watch the normal boot processes. If you see on that hangs then study that.

Why did it take me over a year to phone in a problem to ATT?

You misunderstand, I have downloaded the Ubuntu iso directly from the vendor, it's the Vista iso that's giving me problems, and no, I have observed my CPU temperature at a stable ~30c.

At boot instead of watching the ubuntu screen press the escape key.

When the splash screen eventually shows, it only takes around 5 seconds longer to load Ubuntu. It is taking a significant amount of time on the aforementioned terminal screen with the flashing cursor. When i press escape here though, i am presented with a GRUB screen, with Ubuntu, Recovery Mode, and 2 x Memtests.
