I've got a 9 year old off-the-shelf pc running XP with (I think) SP3. I don't really remember the hdd/ram specs because it's really not used much. I do try to turn it on every few weeks to let auto updates happen.
Anyway, I did start it and update the software in the last week and then bought a new printer and when I tried to load its software from a disc, it wouldn't recognise the printer. It turns out that the printer cable doovy that plugs into the printer wasn't long enough and I've got another one now that fits. So I can't be sure how much, if any, of the printer cd software actually loaded during the failed installation. (I just mention this because it's the last time I did anything with the computer -- I put the new printer cable in today et voila! : bsod cycling)
Today when the pc on, it goes into a continuous cycle of never quite loading windows and into a blue screen of death (BSOD) with error text about the file nv4_disp
(which is, apparently, a driver for the nVidia graphics card).
I guess the real BIG problem is this: I can't boot in safe mode - I can't change the boot mode.
Either in the middle of the cylcle when I'm taken to the boot mode page or when I conjure the page from F8, I can't actually make any choices out of the 3 booting methods such as to choose safe mode. I swapped out the keyboard batteries and nothing changed. None of the usual 3 choices is highlighted so the machine just keeps looping back into this approximation of the loop...
half-booting--->memory dump--->bsod--->unchangeable boot choice screen--->timeout---->half-booting--->memorydump-------->etc etc etc
(I've tried turning the power off a few times too)
I'm pretty lowly on the totem pole of tech knowledge so be gentle.
