Author Topic: win7 classpnp startup loop  (Read 932 times)

so to preface my computer is ten years old---i'm not too worried about keeping it safe at this point, probably going to get another one some way or another after i deal with this. i really just care about the files on the computer because it'd be a pain in the ass to get them back
so my computer froze one night (as it does intermittently, it's just old) and i had to cold boot it. didn't turn it back on afterwards because it was late af and i really wanted some rest. the next morning i left for pennsylvania for five days
when i came back, my computer (windows 7) was getting stuck at "starting windows." so i tried system repair, and that froze after about 30 seconds. so naturally i tried safe mode, it lasted 10 seconds before it (multiple times) got stuck at classpnp.sys
i'm trying to fix it of course, should i get a system repair disk, restore to factory default settings, something like that? i'd prefer not to deal with ubuntu and linux bullstuff but is there anything i can do to save the files or should i just be throwing it off a building


when you get stuck at classpnp.sys, press ctrl+break on your keyboard
according to what i found, it should send you into safemode normally after that

didn't work---i should rephrase, it doesnt just get stuck the computer just flat out freezes

boot to bios, under advanced/system config or something similar find sata controller options and change it from achi to compatibility if possible

some people have had some success with this, if it works you should backup your files asap p sure your drive is failing

ur pc doesnt beat me and fire's pentium 4 dell dimension with 256 mb of ram and a gefore 2 mx400 with windows xp

such a bad boy pc

i know you said you dont want to use linux but its really the only option

put ubuntu on a flash drive from another pc(should be a large one so you can backup your stuff onto it)
ass soon as you see the bios flash screen press f12 or del (or maybe f2, it depends from system to system)
once your into the boot menu select usb boot
you should be booting into linux from the usb drive
once your in go to the file explorer and backup as much as you can onto the flash drive

if it gives you a blue screen on classpnp.sys then its a ram issue - fixed either by switching dimms or throwing out your mobo as the banks are forgeted - try both
