You started Windows 7 without a mouse? Then the OS went to sleep?
Have ou adjusted the power settings in your Windows control panel?
You go to control panel and select system and security then power options then you select a power plan and you choose how the system works with hibernation and sleep modes and if you weant the monitor to turn off after a certian time and the hard drives to turn off after a certian time. Then you can go into advanced power settings and change more options. I usually select never on everything because I don't leave the computer on when it's not in use. so the montor , hard drives , sleep , hibernation are all set to never , that way if I go away from the computer for 20 min or so it's not sleeping and everything turned off. Just the screen saver is on.

Need to know your Processor (CPU) made by AMD or Intel, and the model (example AMD Sempron or Athlon, Intel Celeron, P4, Core2 Duo) Also how much RAM you have (2Gb, 4Gb ) and the make of your Motherboard (Asus, MSI, Asrock) plus model Number. What language do you prefer? Maybe Google translate will help...
Even without knowing any more I think your PSU is too small to power the GPU...

I believe that indeed your PSU is not capable of running that card, minimum Watts required are 300w

You'll need to buy a better one! Try for Antec, Seasonic, Corsair, all good reliable makes.
