OK I'm going to give you several steps to try. Let me know after each step is completed if it resolved the issue or if you are moving on to the next set of instructions.
Go to
Start and then to
RunType in
Chkdsk /r Note the space between k and /
Click
Enter ...It will probably ask if you want to do this on the next reboot...click
YIf the window doesn't shutdown on its own then reboot the system manually. On reboot the system will start the chkdsk operation
This one will take longer then chkdsk /fNote...
there are 5 stages...
It may appear to hang at a certain percent for a hour or more or even back up and go over the same area...this is normal...
DO NOT SHUT YOUR COMPUTER DOWN WHILE CHKDSK IS RUNNING OR YOU CAN HAVE SEVERE PROBLEMS This can take several hours to complete.
When completed it will boot the system back into windows.
Let me know if this fixes the problem
Go
Start and then to
Run ("Start Search" in Vista),
Type in:
sfc /scannowClick
OK (Enter in Vista).
Have Windows CD/DVD handy.
If
System File Checker (sfc) finds any errors, it may ask you for the CD/DVD.
If
sfc does not find any errors in
Windows XP, it will simply quit, without any message.
In
Vista you will receive the following message:
"Windows resource protection did not find any integrity violations".For Vista users ONLY: Navigate to
C:\Windows\Logs\CBS folder. You'll see CBS.log file.
Usually, it's pretty big file, so upload it to
Flyupload, and post download link.
If you don't have Windows CD....This applies mostly to
Windows XP, since
Vista rarely requires use of its DVD while running
"sfc"Note This method will not necessarily work as well, as when using Windows CD, because not always ALL system files are backed up on your hard drive. Also, backed up files may be corrupted as well.
Go
Start and then
Runtype in
regedit and click
OKNavigate to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SetupYou will see various entries
Values on the right hand side.
The one we want is called:
SourcePathIt probably has an entry pointing to your
CD-ROM drive,
usually D and that is why it is asking for the
XP CD.
All we need to do is change it to:
C:Now, double click the
SourcePatch setting and a new box will pop up.
Change the drive letter from your
CD drive to your root drive, usually
C:Close
Registry Editor.Now restart your computer and try
sfc /scannow again!
Thanks to Broni for the instructionsRun hard drive diagnostics:
http://www.tacktech....ay.cfm?ttid=287Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of
.iso type, use
ImgBurn:
http://www.imgburn.com/ to burn
.iso file to a CD (select "Write image file to disc" option), and make the CD bootable.
NOTE. If your hard drive is made by Toshiba, unfortunately, you're out of luck, because Toshiba doesn't provide any diagnostic tool.
Thanks to Broni for the instructionsIf you have more than one RAM module installed, try starting computer with one RAM stick at a time.
NOTE Keep in mind, the manual check listed above is always superior to the software check, listed below. DO NOT proceed with memtest, if you can go with option AB. If you have only one RAM stick installed...
...run
memtest...
1.
Download - Pre-Compiled Bootable ISO (.zip)2. Unzip downloaded

You may have to change the boot sequence in your BIOS to make it work right. To change
Boot Sequence in your
BIOSReboot the system and at the first post screen
(where it is counting up memory) start tapping the
DEL button
This will enter you into the
Bios\Cmos area.
Find the
Advanced area and click

The running program will look something like this depending on the size and number of ram modules installed:
It's recommended to run 5-6
passes. Each pass contains very same 8
tests.
This will show the progress of the test. It can take a while. Be patient, or leave it running overnight.
The following image is the test results area:
The most important item here is the “errors” line. If you see ANY errors, even one, most likely, you have bad RAM.
