Can you check the temperature of your computer? Perhaps it's some kind of overheating problem. That, or your video card is dying.

So that we can rule out any kind of software error, please post your Application and System event logs in EVT format here. (Start > eventvwr.msc > right-click > save as)

Data backup > the easiest way to do this while bypassing your system is to put your hard disk in an external enclosure and copy it into another computer. Plugging an external hard drive is much more painless, but as you said, you can't copy and paste something without having a crash, so Not really sure if the drivers for external USBs are loaded in safe mode, but you can always try it first.

No worries. At least your clarification enables me to gauge your level of technical expertise and adjust accordingly.

To open Event Viewer, click the start button, and select "Run". In the dialog box, type in "eventvwr.msc" without the quotes and click Ok.

> Hard Disk

This involves taking your hard disk out of your computer, and putting it into a special hard disk casing which basically turns it into an external hard disk. This casing is called an External Enclosure.

If you connect it via USB cable to another computer, it is recognized as a removable hard disk. You can then copy all the files into the hard disk of the other computer.
