Hello.
I am writing this for a friend because she cant get to the internet right now. Her computer started to randamly shutdown last night though she could get it up occasionaly. Today however it will not load past the screen where it gives her grapics card info then she gets to a black screen that just shows a blinking curser. She has tried rebooting, a hard reboot, also she tried to see if she could get into bois but it doesnt load far enough. We also tried to see if we could get the windows CD to load to maybe reinstall but wont bring that up either. Her Motherboard is a MSI KM2M Combo-L and she thinks she has an AMD 1.4 athlon cpu. If anyone can help would be appreciated because we are unsure what to do next. Thanks :)
