Windows 7 service pack update failure

[BAD SANTA]

Can anybody please help me as I'm getting pretty fd off with this update.
I have tried three times to get it to install but keeps failing after reboot by about 10%, keeps saying windows failed to install service pack 1 and I can't seem to figure it out.
Any help would really be appreciated.

+rep for the effort but tried all that already.

I think it might be time for a reinstall although I really don't want to in the slightest one tiny little bit. :-(

Yeah,can't think of anything else myself,well there's safemode but you've probably tried that.
And you will have made a backup

 

[BAD SANTA]

Yep, yep and yep but I can't see why it won't install I mean my rig is the tidiest there is I always clean up after myself so something must be up with it do you think my hard drive could have a faulty block or something because I can't see a reinstall from backup is going to solve it, and I really don't wanna do a clean install.

One possibility: check that your system calendar and clock is showing right date and time. I had something similar happen in XP a couple of years ago, and couldn't work out why updates were being cancelled. After several days I discovered I'd inadvertently changed the date whilst checking my calendar. That was all it took!

Here's hoping...

Most common cause is a corrupt registry I think,.
I meant backup of your data,a system image would just give the same result I reckon.

Yer I agree, I think that I'm just going to do a complete clean install and Dban my main SSD as most of my stuff is on my caviar black.
