Computer wil not boot, blank screen

Specs: Windows XP
I have a gateway laptop. I dual boot XP & Linux (Kubuntu). I was restarting to boot in to Linux and the computer won't even boot as far as the bios screen. Just a blank screen, like it is not even powered on at all. Got it back up once after sitting for hours now have the same issue again. Any ideas? Thanks!

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, you must remove both its main battery and AC adapter before you do that.

Consult the Owner's or User' s manual for your laptop model if you need more specific info about how to properly remove and re-install your ram.

If that doesn' t help
- have you DROPPED the laptop or subjected it to some other physical jolt, or have you spilled any liquid on it, or exposed to any liquid (it doesn't matter whether it was running at the time or not) , since it last worked properly, or lately??

- Check your hard drive with the manufacturer's diagnostics.
See the latter part of response 1 in this:

Hard Drive Diagnostics Tools and Utilities

If you don't have a floppy drive, you can get a CD image diagnostic utility from most hard drive manufacturer's web sites, but obviously you would need to make a burned CD, preferably a CD-R for best compatibilty, on another computer if you need to.

If the hard drive itself tests okay, any data problems found can be fixed, one way or another.

Thanks for your help. After looking into the issue further over the weekend it appears to be a CPU over temp issue. After monitoring the temp If I keep it under the recommended temp for my CPU I don't have any issue. Many thanks for your help.

Oops - I missed noticing your last line in the first post.

Your cpu should NEVER be overheating to that point!

You can't overclock most laptops, or choose a higher cpu core voltage, which can certainly cause overheating if you overdo it, so it's probably not that it's caused by.

These are what what commonly causes cpu overheating on laptops...

- obstruction of the openings where air enters and/or leaves the laptop base - make sure there's nothing interfering with air getting into / out of those openings, and that there is a reasonable amount of air space near where the openings are. If you use the laptop on your lap a lot, you may need to have something between your laptop and your lap.

Once you've used the laptop a lot, these thingsare likely to happen eventually .....
- the cpu fan, or whatever fan it has inside it if it isn't on the cpu itself, may no longer be able to spin at it's faster speeds, probably because there is too much friction in the fan's bearings - if so, the fan needs to be replaced.
- there may be too much accumulated "mung" inside the laptop - dust, lint, etc. - e.g. that is likely to happen at a faster rate if the laptop is often used in a location with wall to wall carpet and/or in a smoker's environment - in that case the laptop needs to be opened up so that accumlated "mung" can be removed, from the air passges inside it, and from the fan and heat sink(s).
