|Your cpu may be overheating. When you experience problems, as soon as you can after that, go into the bios Setup and find the current cpu temperature reading and tell us what that is. |
For laptops, the most common reasons for the cpu getting too hot are:
- you're obstructing the openings in the case that are for the intake and output of air from the case
- there's too much accumulated mung - dust, lint, etc. - inside the computer case air passages; that's often worst near the fan.
- if the laptop has been used a lot, the fan inside the case is failing or has failed.
A common thing that can happen with ram, even ram that worked fine previously, is the ram has, or has developed, a poor connection in it's slot(s).
This usually happens a long time after the ram was installed, but it can happen with new ram, or after moving the computer case from one place to another, and I've had even new modules that needed to have their contacts cleaned.
See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
For a laptop, or netbook, you must remove both its main battery and AC adapter before you do that.
For a brand name computer, see the Owner's or User's manual if you need to - how to remove or replace the ram is usually in that - it may already be in your installed programs. If you can't get into Windows, it may be on a disk that came with the computer, or you can go online and look at it or download it - it's in the downloads for your specific model.
