Windows 7: OS re installation failure.

I recently received a virus that did a plethora of things and one of them was trying to delete system 32. To counter this I tried to reset my comp to a previous date. After pushing it to the farthest date and still dealing it I decided to reset to factory default without backing up any files. Everything goes great but when it starts installing the service and the OS it says the installation can not continue and the comp must be restarted. My comp is a HP TouchSmart 600 PC running Windows 7 Premium 64-bit. I have disconnected everything from it and tried running it on safe mode but I do not know how to restart it without pressing the power button but that just ends everything.

If you have run Factory Recovery from it's partition on the HD and it fails then your options are to try again, boot the Recovery Disks you should have made when you set up your Computer, or order them from HP Tech Support, HP Backup and Recovery Manager

You can also find a Windows 7 installation DVD to clean reinstall using the PRoduct Key on COA sticker - a vastly superior install of just the OS without the HP Factory Bloatware or useless HP utilties which have much better versions built into Windows 7. Here's how: Reinstalling Windows 7
