Alright so I have 2 problems. One is that my 1 TB hard drive (which holds my 50 GB of steam crap) has shown to be at risk in the windows partition manager. So I was like, "Alright whatever, I'll just run a check disk and if things don't patch up I'll backup my important stuff and reformat". Problem is is that chkdisk is best run in safemode to keep it from being held up because something tries to access it. True enough, chkdisk just hangs at a certain point in chkdisk when running in XP normally. So here comes the second problem, I try to go into ANY safe mode configuration (networking, normal, etc.) and it hangs on that list of files that boot. The last file it shows is mup.sys. Apparently quite a few people have this problem, and it's just so happens that there's a least 10 different causes. The ones I'm most likely to have are: Corruptions on C drive (had this computer since Christmas 2006, haven't reformatted C: once I was actually going to do that but then this problem occured) Too many things sucking power from the power supply (laser mouse, blue LED backlit gaming keyboard, 3 HDDs in a computer meant for 2 HDDs one of which is 1 TB, and a graphics card that requires extra power from the power supply). So yah. Virus, kind of unlikely though since I don't do many things that put me at risk for viruses and nothing else seems to be acting weird. I also have a virus scanner that has on access scanning, so it should catch a virus as soon as it tries anything funny. Corrupted spots in the registry (again, I haven't formatted C: for awhile) Also the possibility that I no longer have a floppy drive in my computer, and my BIOS was meant to detect this floppy drive. I replace my floppy drive with my 3rd HDD and covered the hole that it stuck out of. I even get a message everytime I boot up my BIOS prompting me that it couldn't find the floppy drive (even though it's out of my BIOS's god damn boot sequence). The final problem is that maybe the power supply or other recently installed hardware is failing. This is a shit load of stuff to test. I honestly have no idea where to begin, and this is obviously quite a big problem in case I get some sort of virus and need safe mode. Has anyone else had this problem before, or does anyone have any suggestions? I suppose running a chkdsk on C: would help, but I don't know how without safe mode. I think I have my original XP installation disk, but I don't see any option in my boot menu to boot instructions from the disk.
