Why the hell can't my computer run disk defragmenter?

[Feedmenow]

I get this error:[attachment=1:14a7pr81]untitled.GIF[/attachment:14a7pr81]and when I try CHKDSK /f, I get this[attachment=0:14a7pr81]wut.GIF[/attachment:14a7pr81]

hitting Y, then hitting the enter key, and then restarting gets an error, and then it goes back to restarting the computer normally without anything getting fixed.

So, what do I do to get my computer defragmented? It's slowing way the hell down.

Try disabling your anti-virus software, some realtime scanners can fuck up disk utilities.

Still get the error in defragmenter, and shouldn't that have worked after restarting if anti-virus was the problem?

I believe you need a certain percentage of unused space to store files in while it performs the defrag? I could be wrong, but I remember reading this in a computer repair class. I'm not entirely sure what the error message you received means. I'd try deleting some files you don't need if your PC is close to full and then attempt a defrag again.

Check disk should run on your next boot. Its the equivalent of the old Scan Disk which checks your drives for errors. You'll probably want to boot the computer into safe mode, and on a reboot, let it do the scan disk/ check disk, if it doesn't come up since it's scheduled, I'd run a scan or two on your computer for viruses/spyware. However, I think you should be able to force a check disk during boot, not sure though.

Disk space is mostly free, but what's worrying me now is that safe mode crashes whenever I try to load it.

I'll be virus scanning for a bit. If it's not a virus then a reformat would be necessary, wouldn't it?

Not sure what's happening... but something isn't letting that CHKDSK run, obviously, so when you go to run defrag you get that message... do you get an exact error message before it boots up when it tries to run the chkdsk? Whats the wording if you can see it fast enough?

[Feedmenow]

And now the entire system's fucked.

Whenever I try to run safe mode, safe mode with networking, or safe mode with command prompt, (I think) it loads to some file called mup.sys before restarting.

Trying to run windows normally or in last way that worked causes it to load for a bit, then get a bluescreen error and reset within half a second. I tried to read what the error says but it closes down super fast.

Doesn't sound too good broseph. Seems like your're going to need a reformat. If you can get the error at all could possibly help, but it sounds like its getting worse and worse.

Boot to XP cd and choose to run the recovery console. Run chkdsk /p from there.
