CONSTANT blue screens of death

Ok, just had three BSODs at the inconveniently timed sort of stage. Was in Windows, Chrome crashed so I clicked re-launch, then BSOD. It starts rebooting, I go away to wash something, return a minute later and it's on the beginning of the BIOS info screens, having clearly BSOD'd while I was out of the room. It starts rebooting again, and this time shows the startup repair or normal boot option, I couldn't choose normal as no keyboard was connected and startup repair was the default, so I let it continue. It showed the black screen with the white windows loading files bar, then BSOD. I get annoyed, so just press the power button when it's about to start booting again so that it stays off. When everything was spinning down, I think I heard some horrible clunking. I think on one of the BSODs I spotted the ntfs.sys bit, but I can't remember fully and clearly I haven't been able to get the files off the computer as it seems rather screwed at the moment, but I will try to get them uploaded as soon as I can.

ok, attached is a zip containing all the latest DMPs, I think all the ones since between the latest lot you've had and the present time. Hopefully they will shed some light on the issue

So, the computer is back. After a few months of communication with HP support, they collected the computer for repair. It came back worse than it had been. It went back again. The second time, they not only replaced the motherboard again, they also replaced the graphics card. And now it works (touchwood). To be on the safe side, I've swapped the 300W HP PSU for a 500W one, as my theory is as follows:
The computer needed more than 300W of power. I mean, really, just look at the other specs. 300W seems like cutting it a bit close to the line. So I'm guessing the graphics card needed more power, some bad stuff happened, which also affected the motherboard (as when I removed the graphics card and put in a less powerful one it still wouldn't work) and it all went wrong. I do think it a bit odd that HP didn't put in a PSU more suited to the machine, but they do seem to be determined on keeping all components the exact same makes as their previous, deceased, counterparts.

Should I mark the thread as solved? As I guess the issue is solved, but in case anyone else happens to have the exact same issue, "pray your PC is still in warranty and get the manufacturer to fix it" doesn't look like the best conclusion.
