I recently removed Google Chrome from my hard drive and downloaded Firefox with Iolo System Mechanic, and I believe that I removed some essential elements because shortly after I accomplished this I no longer can access a start menu and my desktop icons are all gone. I have tried last known good config, I have run a chksys, I have tried system restore, and I have tried safe mode but I have no desktop or start menu there, either. I opened a new account and I have no access to explorer whatsoever, and it will not run. I have uninstalled and reinstalled it, and it is listed as a program but will not load. My only access to my programs, which still seem to be intact, is through the task manager. I have ran several virus scans and malware programs, and several items were quarantined but the problem still exists. When I type explorer.exe into the taskbar, the start menu flashes briefly and is gone again, the same when I type "control" or "desktop." I have tried the kelly's corner downloads, but I can not locate them on my hard drive when I save them or run them from the download menu for some reason. I am running Windows Xp, and I have no disc and cannot find the i138 file on my drive. I have been searching this forum and several others and have tried everything. I do have the product key and activation code for Windows that was installed to my pc, but I have no way of doing a repair, and I am afraid that I will lose my photos and data. Any help would be greatly appreciated, and as I said I have searched and tried every thread on this forum and nothing has worked as of yet. Thank you in advance!
