In the reboot loop since Tuesday night. Automatic updates are turned off, but that doesn't not seem to stop them.
This is where get into "where did I put that system recovery disk I made five years ago?"
I can get to startup repair, which fails, and to the screen for choosing repair modes, where neither "repair system disk," "go back to an previous system image" nor "restore to OEM system image" will work.
I can boot and run an Ubuntu 10.4 from DVD image, where I can get to the Linux disk utilities and could once see the internal drive with undamaged file systems, mount the partitions and look at the files.
After a few more startup repair attempts, Linux no longer finds the drive on the SATA controller. This is a Dell XPS 8300, a model known to have a fault in the chipset, statistically small risk of intermittent failure of SATA interface to the bus. Early examples got a motherboard replacement, this example was supposed to have been manufactured with the corrected bridge chip.
This is the second time this year an update has failed, last time I got it repaired to bootable and backed off the updates.
I think my next "power" computer for photo editing and video production is going to be an iMac, as right now they are selling for a lot less than what someone else wants for a good IPS monitor and XPS-class box with equivalent processor, memory, storage and less capable graphics. A leap of faith, since I've not used a Mac since the Mac II in my Unix workstation test lab twenty-some years ago.
Decision partly driven by my collection of dead Dell computers (three Inspiron laptops, three desksides including two in "workstation" class). Three of the six taken out by disk controller failures.
Pretty much most of the "failures" you have experienced is more likely caused by the electrolytic caps on the system board and or power supply failing..
Can't escape this now days and pretty much any electronic equipment that has switching power supplies (which your system boards have a bunch of built on board switching regulators)will eventually fail (built in obsolescence) guaranteeing that you are going to get 4 to 5 yrs of use at the tops.
Even "Macs" can and will fail due to these caps if you keep it long enough and when that happens you can only get parts from Apple..
For desktop PCs why don't you simply build your own?
Granted it will not be as cheap as say a Dell, HP or other name brands but it will allow you to take control of the quality of the components..
Pretty much a straight forward process, research the board brands, gammers look for certain things they like, video intensive editing folks like other things they like, most will have recommendations of the boards they find reliable..
Match processor and memory, throw in a case with HD/DVD drive and load OS..
I haven't bought a new board for a couple of years and it was a Intel Atom mini ITX board with dual core Atom processor at 1.6 ghz built on the board for a low power project.. The board plus 2gig of ram, set me back a whopping $70 at the time, put it in a small Mini ITX case for $40 added a 250gb HD and DVD burner for a few bucks.. The Atom PC I built only sips 25W of power!
All told I had a whopping $200 not including the OS..
For the OS I bought a copy of Win7 OEM version for $135 (OEM version does not have MS tech support like the retail has)..
