My laptop computer keeps showing a black screen with "computer system not found..." after it sits and idles for awhile. I've had to take out the battery, reinsert it and restart it (normally) and it runs okay again, until it sits idle. What's going on?

You mean 'operating system not found'? Does it do that when first booting up or do you mean it's running OK and then later you look at it and see that message?

Assuming the former, that means it can't find the system files on the drive it's trying to boot from. Since you eventually get it going it sounds like your hard drive is slowing down. On some computers there's a 'hard disk pre delay' in cmos/bios setup that allows more time for the drive to spin up and be recognized by the bios. You may want to check to see if yours has that option. If so, set it to about 6 seconds.

Probably a good idea to run a diagnostic on the drive, although sometimes when a drive acts that way a diagnostic will tell you it's OK. That's because a diagnostic can't test the drive's initial state when booting up; it can only test it when it's running OK. But a diagnostic should be available from the drive manufacturer.

If it's giving that message suddenly after running OK for awihile it sounds like the drive may be failing. Again, try the diagnostic.

It is the latter... when my computer is running and then I see the message... "operating system not found."

Sometimes bad ram can cause a hard drive to give error messages but I think more likely it's the hard drive itself. I assume windows 7 has a defrag utility. Run that first and see if that helps. But it'd still be a good idea to run a drive diagnostic. The drive model number should show in cmos/bios setup if you're not sure what you have. Check the drive manufacturer's site or post back the model number and maybe we can find it.
