Hi Everyone

I can run and finish a quick scan in Microsoft Essential

But when i went to run a full scan it ran for four hours and got hung up at the 80 to 90 % of being done
and then i got a box that popped up:

SVCHOST.EXE
tHE INSTRUCTION AT 0XOOOOOO
the memory could not be read.
Click to terminate/Cancel to Debug

Thank You

Joe
Hi Joe.

The first thing I would do is run an overnight memory diagnostic.

There are two programs that are normally used to test computer memory, Memtest86+ and Microsoft Memory Diagnostic. They are available from the following locations:

Memtest86+ (Downloads are about half way down the page)
Microsoft Memory Diagnostic

They are bootable CD ISO images. You don't burn the iso file itself to CD., you create a CD from the iso file using your CD burning software. There is a good freeware burner called ImgBurn which will do this easily.

With either, crank it up when you go to bed and let it run overnight, or if you want to check on it as it runs, do so during the day, but let it complete a minimum of 3 complete passes.

Another possibility is over heating. Power the computer down and remove the power cord. Open the case and see what kind of dust has accumulated. A can of compressed air is good for cleaning out fans and heat sinks, vents, etc.
One other possibility pointed out to me by one of the other techs here is that you may be infected.

If the memory diags don't show anything and the computer is clean, then go to the Spyware / Malware / Virus Removal forum, read the info there and follow the posted directions. Once you receive a clean bill of health, come back here if you have any additional questions or concerns or it turns out not to be a malware problem.

Please be patient as that is a very busy area. If you do not receive a response in 3 days, post a message here: http://forums.whatthetech.com/What_Do_If_Y…ays_t78698.html
Hi Ztrucker Today i tried running a full scan of Microsoft essentials and it failed and shutdown the PC Then i tried Windows Live One Care safety scanner and it failed and shutdown the PC I Came from the virus forum already and the PC Appears to be infection free. I will run the memory tests tomorrow. Thank You Joe PS. The only time the PC shuts down is when i run a Anti virus Scanner on Full Scan Ive seen the pc run for 48 hours straight over the July 4th weekend so i don't believe it to be the fan.
Sorry, forgot you had already been to the malware area.

If the memory diags don't show anything, I would then try a hard drive diagnostic. If you don't know the manufacture or your hard dive you can usually get that info from the Disk Drives area of Device Manager (Start then Run, type devmgmt.msc and press Enter). If not you'll have to remove the drive to look at it. Once you have that information go to their web site and download the drive utility and see what it says about the hard drive. It will be an .iso file you create a bootable CD from.

One last suggestion for now. Run chkdsk /r to see if there is a file system problem. Click on Start then Run, type chkdsk c: /r and press Enter. You will see this:

The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N)


reply Y then reboot.

If that doesn't run or complete for some reason, try from the Recovery Console. You are going to have to get into BIOS Setup on your computer to set the CD/DVD drive as the first bootable device, so you can then boot your XP CD.

How you do this varies with each manufacturer. Normally you press F1, F2, F10 or Del when you see the manufacturers logo. Often there is a clue somewhere on the screen when you boot normally telling you what key to press. Some computers (most newer ones) have a key you can press (often F12) to bring up the Boot Menu from where you can select the CD/DVD drive to boot from.

If you don't have an XP CD, download and create a bootable CD from the .iso file XP Recovery Console

You don't burn the iso file itself to CD., you create a CD from the iso file using your CD burning software. There is a good freeware burner called ImgBurn which will
do this.

Boot the CD and at the first opportunity, enter R to start the Recovery Console.
Next, choose which XP installation you want to login to. Normally this will be 1.
Lastly you will be asked for the Administrator password. Just press the Enter key as the Administrator does not have a password (unless you gave it one, then you would enter it).
From the command prompt, enter: chkdsk c: /r
Allow it to complete undisturbed. It can take an hour or more depending on the size of the hard drive.

Remove the CD, type exit and the computer will reboot.
Hi Ztruker I did all the things you said and everything came out ok I then downloaded and was able to finish a full scan of Kapersky. So i then tried again a full scan of Microsoft essentials and the PC shut down after 90 minutes. So i tried a new program i haven't tried before called A-squared… which found 1 high priority and 1 medium Malware So i then tried again a full scan of Microsoft essentials…and it was finally able to finish a full scan and the PC has been running since Late Sunday with no shutdown :) Joe
Yikes! So there was some kind of malware and apparently it was causing the problem or at least that's how it looks. Glad you got it fixed though. Sounds like all is well (for the moment).
