Windows 7 just randomly decided to mess about with my profile

Hello.

So, I went on my computer and I am the only account, therefore an administrator. I typed in my password, I logged in and it took longer to load and showed me a message saying "preparing your desktop", which I had never seen before. So I waited, I was logged in and weird things happen. The little info said something about my account was logged in as a user, so I'm not an administrator and I'm the only account. Some of my icons were messing, some weren't, and I had a black background.

Today, nothing is different except I have the windows 7 standard wallpaper. I restarted, logged out back in, etc still the same, I have bullguard, malware bytes and comdo. When I press f8, the run windows in options don't come up, since I have a gaming pc. Instead there's this option where the megabytes are like 9038339373 and I think that may be my one. I used it, and it was still the same.

I'm stuck so far.., any help?
Thank you for reading

Thank you for the fast reply and warm welcome

I will read that now

Btw, why does a corrupted profile happen? What's wrong, etc

Cheers

Oh yeah, it doesn't give me the option to boot in safe mode

I have a custom built
If I repeatedly press f8 it gives me options in a grey box to choose from. The are 4. One is Realtek adapter so I can't boot in safe mode.

I didn't have much 'good things' on this profile

Cheers

Also, I made an administrator account on my other admin account

Oh

Thhanks

I'll try it later in and report back with results
