except i noticed that my computer clock has been set to 1/1/2007 which is really strange.
the os gets the time and date from the bios on start up, and a dead battery means it's going to be wrong, and why that happened.
A message appeared on my desktop saying this version of windows is not genuine
that may have been caused by the wrong time and date too.
I freaked out thinking it was a virus so i did a reinstall of windows 7 and computer seems to be working fine except the text is not as sharp as what it used to be.
this might be because you have done a clean install and all your needed drivers are not yet installed.
I'm at my wit's end. It's driving me crazy.
don't worry to much, the pc boots and works and you haven't lost any of your important data, so things aren't as bad as they may seem.
right first understand, the pc boots fine now because it hasn't been disconnected from a power source but as soon as you do disconnect it, you will be in the same position as when you were to start with.
the only fix for that is to put a new battery in the motherboard, the battery is not vital because a pc will boot even without a battery in it, but it does mean because the bios settings are lost again you will get the screen in your first post and need to go into the bios and set things correctly before booting to the os otherwise you may get the os not genuine message again.

next you will need to know the make and model of your pc, then go to the manufacturers site and download the latest drivers for it, usually you need the chipset drivers and graphics drivers, once downloaded just click on them to install.
also check your os has all windows updates installed, this could take any where from hours to days because the windows servers seem to be running very slowly from my understanding for older operating systems like windows 7.
if you need more info on how to do all this then we'll cover that in detail later.
once those 2 things are done you should find you have no more problems, so now it is time to create your backups, first to make sure if your drive ever failed you don't lose your data, and secondly if you make a drive image backup then this can be used to quickly and easily install everything to exactly how it is when created.
ok, hope that eases your mind a little and helps you get everything back to how you like it.
