"Do PSU's "gradually" fail then?"

In most cases yes.  Most common cause? Build up of dust and grime in the
venting fan causing over-heating.

Although with your PC slowly going down it's just as likely you've got a
hard drive beginning to fail. As you use it, the machine is getting warmer
and more suseptable to tolerance failure from any mechanical movement, the
read heads don't track the disk as well and so don't pick up the data or the
drives motor simply doesn't spin up properly to achieve enough rpm to read
without error.

Actually, thinking about it, if your power supply is going down, it may
induce hard drive failure, low power so hd motor can't spin up properly.

Also check, as Gerry has just discovered and I hadn't considered, physical
seating of components.  This need not be because you've dislodged anything,
it can happen simply through vibration.
