    AVG Scan Results

    I'm trying to figure out why my PC has been showing 100% CPU utilization for the last few days, and booted into Safe Mode to run some adware, spyware, and virus checks. AVG Anti-virus Free Edition just finished a scan. It didn't find any viruses, but did report "reading error" on both the Partition table (MBR) and the Boot sector of disk C:

    Do these errors mean anything?

    John,
    That just may be the cause of your problems.
    I would first run a chkdsk /f on your C: drive. Start>run>CMD>type chkdsk /f. It will take some amount of time to do it, so go have dinner and come back.

    ANDOR

    Boot to your XP CD and run Recovery Console. From RC, Run "fixboot and fixmbr" separately.
    A link to MSKB article on fixmbr is at FIXMBR

    A similar one fixboot is at FIXBOOT

    CHKDSK finally ran to completion yesterday, several meals after I started it <grin>. No improvement in the PC's operation after that, so it's going to the repair shop this morning.

    John,
    You didn't try the "fixmbr and the fixboot" repairs?

    Not after CHKDSK took almost 24 hours to run [img]/forums/images/smilies/sad.gif[/img] When I took the PC in this morning, the tech pointed out that the offending item in Task Manager is just identified as System--not as System.exe. So he thinks we're looking at some kind of malware/spyware infection, not a hardware problem. I might have been willing to try a "boot disk with AV" approach, but this is the only "working" PC I have with a CD/DVD burner, and who knows how long burning a disk would have taken. I plan on cooking up a second PC with a burner real soon <grin>.

    Well. let us know what the tech comes up with anyway.

    Just for your future info, fixmbr and fixboot are really "quickies" and don't take long at all. Not like chkdsk with the "f" option. <img src=/S/whisper.gif border=0 alt=whisper width=29 height=17> <img src=/S/snore.gif border=0 alt=snore width=32 height=15>

    Bob,

    Shop struck out, so I have the PC back with the same problem. Their next step would be to wipe the hard drive and reinstall XP. On top of the $85 they would charge for that, I'd have to pay another $100 or so for data backup prior to the wipe. I'll first try fixmbr and fixboot, and then look at the other suggestions I received. I can put my old 40 GB IDE drive back in as a second HDD, and backup my data files to it, if I decide to go with the reinstall.

    John,
    So the "shop" struck out on the fix? Did they charge for the strike out too?

    Your last ideas sound like a plan to me. A lot cheaper also. Keep us posted.

    Be very skeptical about shop backups and try to make your own. My sister took her computer into Best Buy and they said they would "try" to make a backup. Because the computer wouldn't boot, they didn't make one, and they charged for it anyway. As you point out, it is not difficult to stick the drive in another computer to access it, but apparently this would go above and beyond the normal procedures. Uggh. So long digital photos.

    Re: AVG Scan Results

    I know we need to be careful of Lounge rules here, but this whole scenario echoes my local experience with more than one "service department" especially in the so-called superstores. John, I think you're making a wise move to try to rectify this on your own. If you can copy stuff from the drive and get on with it, I hope you'll be better off in the long run. Good luck...

    Yes to both questions.

    >> Your last ideas sound like a plan to me. A lot cheaper also. Keep us posted. <<

    Fixmbr and fixboot didn't help, so I guess I'm down to to wipe and reinstall XP. I actually have a full backup from 4/1, done with Retrospect, on an external hard drive. I think I just have to backup MS Outlook's e-mail file (for mail since 4/1), and make a copy of the Retrospect installation file (I downloaded it from EMC originally). Once XP and Retrospect are up and running, I should be able to access the 4/1 backup (I can't now because the CPU problem is keeping all my USB devices from working).
