Disconnect all peripherals from your computer. Boot from your install disc & run _*Repair Disk*_ from the utility menu. To use the Install Mac OS X disc, insert the disc, and restart your computer while holding down the C key as it starts up.
Select your language.
Once on the desktop, select Utility in the menu bar.
Select *Disk Utility.*
Select the disk or volume in the list of disks and volumes, and then click *First Aid.*
Click _*Repair Disk.*_
Restart your computer when done.

Have you tried running the extended version of the Apple Hardware Test? If not, do that. It will be on one of your original gray system discs.
Also, download and run SMART Utility:
You can download the demo and run it several times for free. It will give you a very comprehensive analysis of the physical health of your hard drive.
If you have access to an Apple Store, they can also run an extensive hardware test for you.
What you want to do is to run any hardware tests that you can and see if you can get any error codes that might point to what the problem is. If you do, then you can look into what can be done to fix the problem, and if the problem is easy to fix, then you can fix it and have a reliable computer that should easily last for 5 months.
If you are still using the original hard drive, it could easily have begun to go south and/or gotten too full. The average useful life of a laptop hard drive is 3-5 years, and some fail sooner. If you find out that yours is failing, you can replace it or alternatively, run your Mac from a bootable clone on an external drive, preferably FireWire.
In the meantime, it would be prudent to make a good up to date backup and keep it up to date if you don't already have one. If you are headed for a crash, you want your important data to be safe and sound.
One good way to do this is to have an external drive with 2 partitions. One would be for Time Machine, and one would be for a bootable backup clone using Super Duper or Carbon Copy Cloner. It is especially good to have an external up to date bootable clone, because if your hard drive were to fail suddenly, you can boot from the clone and continue working.
It's important to find out why your Mac keeps crashing. Once you know why, you will have a much better idea about what is wrong and what it would take to fix it.
