So, the 403 error is gone;
Yes or No?? Post back if No, and I'll make further recommendations. Basically, if SFC fails to complete, you most likely have badly corrupted Windows system files.
SEATOOLS passing indicates your hdd is most likely ok. After your Personal Data backup (you didn't mention whether you had done this or not); you should attempt to reinstall Win7 Pro onto the Seagate 1TB hard drive from Lenovo Factory Recovery Discs. If you don't have them, you should also be able to use the
Lenovo BACKUP AND RECOVERY utility to restore you PC to Factory out-of-the-box condition from the hidden recovery partition. Download the
THINK CENTER USER GUIDE from Lenovo website here:
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/thinkcentre_pdf/53y9906.pdf The Guide tells you how to create
RECOVERY DISCS and how to access the
RECOVERY PARTITION (
<f11> key on bootup).
Upon researching specs on your PC, it appears that it shipped with either Windows XP or Windows Vista. The Recovery discs or Recovery partition of course wil
ONLY restore it to XP or VISTA, whatever came on the computer when you first purchased it---
NOT WINDOWS7 PRO!!! This means that if you did the upgrade to Win7 Pro, you'll have to locate the Win7 Pro disc you used along with the License COA key. The Microsoft Windows label on the outside case of the PC will not activate your Win7 Pro. If you didn't do this upgrade yourself, but rather paid someone like a Tech to do it; you'll have to contact them for the Disc and Key if they are still around. If not, you'll have to purchase a Win7 Pro disc and key online (no longer sold in retail stores since 2011). This will cost you around
$120-$140 US. If you bought the upgrade from a reputable store such as Best Buy-Geek Squad, they may reinstall the upgrade for you for a fee; maybe under $100.
Bear in mind that when you upgrade the Windows to Win7, it may come with IE9 or IE10 depending on the media you or your Tech may have used. When you upgrade to IE11, ensure that you have either 32bit or 64bit version of IE11 when you perform the download--otherwise IE11 won't install on your PC at all!
Once this is all done, your 403 error should disappear!
Best of luck,
