Trouble with running any program in Win7 32

Hi, my issue is though all my files, documents, start menu & icons are where they should be if i try to access them it gives me the message

"Windows cannot acces the specified device, path, or file. You may not have the appropriate permissions to access them."

There is only my profile on the install of windows and I am the administrator, i've tried from the start menu - run - CMD with admin privileges and it gives me the same message. I've tried to Take ownership but that option isn't available in the drop down menu - it doesn't restrict me accessing any file or folder just the running of any file...

In safe mode i've ran AV & AS programs including - Spybot S&D, Superantispyware, Avast, Malwarebytes AM & Microsoft security essentials - and none of them have found anything except a few cookies the first time through which it removed and changed nothing, as you would expect... I am also running Online Armour as my firewall but had turned off the program guard to install couple of programs, but not the webshield.

As i mentioned above in Safe Mode i can run most programs no problem including the AV's. I also run Msconfig in safe mode to see if i could see a service or startup program i don't recognise as i've experimented with alot of them when i was running XP and there doesn't appear to be something that looks out of place.

Would appreciate any help or advice i can get as this is a new one and very frustrating... hate using the older laptop for everything.

Thanks in advance,
Steve.

Go to Control Panel>User accounts and set up another Admin level account to run under for awhile to see if the problem replicates. If so then I'd run SFC -SCANNOW Command and possibly a Repair Install and also work through these Troubleshooting Steps for Windows 7 - Windows 7 Forums

Welcome to Seven Forums, Steve.

I was just wondering if this problem started immediately after you installed Windows 7 or cropped up later. Were you able to activate Windows? If the problem started from the very beginning then the best thing to do would be to reinstall Windows 7 again. Otherwise you may follow the advise given by Greg and if you do not succeed then reinstall Windows.

Gregrocker -Thanks for the reply, I've made another user with admin privileges, and the exact same results - i can't run anything in full mode including command prompt, in safe mode i ran the SFC but it found no problems - as i can run programs in safe mode.. i'm going through most of the troubleshooting steps but most i've done or found no issue yet i'll keep going through them. I'll also try to use a previous restore point to see if that works before doing the repair install - Will the repair install work from safe mode, as i can't running anything in normal mode ??

Amarnath - Thank you as well for the reply, no it isn't a new install, but if i have no other choice i will be re-installing if i have nothing else works.

Unfortunately you cannot run Repair Install in Safe Mode.

Hopefully you have some earlier Restore Points so you can work backwards to find a point before the problem began.

If not then here's steps to get a perfect Clean Reinstall - Factory OEM Windows 7 which are the same for retail Win7.

Yeah that was my thought, that repair install wouldn't run in safe mode.. lets hope the restore points work, Thanks for the help and replies (i'll add rep to your replies)
