Windows 7 went crazy

Hi, my windows 7 home premium x64 is very weird.
First my computer dosen't show me what processor i have and how mutch ram i have installed, aero turned off.

1) I tried to fix this: Re running the Windows experience index. Didnt work.
2) Scanned with Malwarebytes Anti malware and with Microsoft Security essenitals my whole computer thinking it can be some virus. Didn't show anything
---------------------
Second problem Windows Security center turned off and cant be turned on "windows security center service cannot be started" error pops up. I tried to turn on it manually at Services. Didnt work. I tried to turn the service on from msconfig but still little X is under the flag. I don't have any system restore point created.
And then i thinked mabye i need to change my Antivirus from MSE to AVG, Avg gave me error that "3rd party cannot be installed. MSI action failed" so i installed Again mse.

Can you tell me is is some kind of virus in my pc or is just windows broken files missing etc..

I can't test something like repairing windows because im scared of my pictures. 7years old images on my hard drive and i don't have anywhere to copy them atm. So please help me, because Sevenforums is was my only opinion where to go with this problem.

I think i will Copy pictures over to USB and install whole clean new windows maby this can fix my problem.

I think that is the best idea for now. Try to scan your FDD with your updated antivirus after fresh windows install before you copy your data back to your drive.

FDD? What's that. Do you mean HDD?

I think the first thing to try is another anti-virus scan, just in case. Use Windows Defender Offline to do this. This is not Windows Defender nor Microsoft Security Essentials. It is another Microsoft program designed to scan and remove viruses before Windows boots. This can get rid of more stubborn infections.

If that scan comes up clean, you should either try a Clean Reinstall or a Repair Install if you cannot back your files up to an external disk. A clean install is pretty much guaranteed to work but a repair install might not. However, a repair install is easier as all your documents, settings and programs will not be affected. Details of both are located in the tutorials.

If you want to go ahead and do a clean install instead of following my other advice (which is fine) be sure to follow the tutorial to do so. It shows how to do so without a Windows 7 DVD to save you buying one if you don't have one. It is also full of helpful advice on what to do afterwards to make sure you get the best result.

Hope this helps

When you said USB, I think its a FDD (Flash Disk Drive).
