Laptop Flashes then Freezes
This has only been happening for a week out of nowhere:
I can run Windows for 30 seconds to 5 minutes before the screen flash, then everything freezes. I reformatted, and it still happens, including on bios and on the setup. On startup before Windows even boots it sometimes locks up. What do I do? I'm sure its not about memory.
It's not a virus either, I reformatted, and it's still doing it.
edit: btw the laptop is a Thinkpad T40 series, a little old, but still worked fine up until that point
