BAD CAPS or a hard drive going out. You could research the BAD CAPS and inspect for that issue.
The HDD is a little hard for folk to wrap their heads around. I find folk will not take the early warning and save their files or prepare for the end. That's your choice.
On startup my computer stops at the MB splash screen. To get past it, I hit the hard boot (sometimes twice) and it restarts but doesn't wait at the splash screen, it goes on to boot, and works fine. ???
How do I fix this? I have re-installed XP SP3 once again..
