If these pink squares are video artifacts: "It was the standard screen but it had unusual pink squares on the screen." My first guess is that you may have a bad stick of ram or failing video chipset. If you can burn a dvd or cd or have a flash drive (back it up first you will need to format it) run memtest86: http://www.memtest.org/#downiso
To boot to a flash drive (plug the flash drive in when the computer is off) with the computer off, power the computer on, start tapping F12 on your keyobard and use the arrow keys to boot to the flash drive or dvd (whichever you use for memtest86) You should run 3 passes and have no errors. If you have errors you will need to pull a stick of ram and retest, always unplug power and remove the battery when removing ram or putting ram in.
If you can not get to the post screen (the toshiba screen) and you only have a black screen. You can try to remove a stick of ram, if you have 2 remove 1 and try to power on, if it still has a black screen, put the pulled stick back in and pull out the other stick. You will want to try both sticks of ram in both slots eventually.

If the computer is overheating, dust out the exhaust and intake slot (where the fan pushes out and pulls in air), overheating a computer even 1 time can cause permanent damage. If your ram size is changing at random you likely have a bad stick of ram or perhaps a problem with the motherboard/cpu ram controller. Dust out the computer first and then run Memtest86.

I have got a new computer now (FYI)
Also the computer is on its fan again and I will run memtest after cleaning out the fan, does it need to be opened up in any way?

It is always nice to have a new computer
With the old one, if you can get enough air through the intake and exhaust you probably won't need to take it apart. As long as the fan does not have problems canned air should be enough to clean most of the dust out. If you can feel hot air coming out of the exhaust when the computer heats up, it should be good to go.
I still might suspect a ram problem because you mentioned the ram size changed and this might go along with your pink squares problem. If ram amount shows incorrectly at a bios level there is some issue with the ram, or the memory controller which is probably part of your main board or cpu. Video defects usually point to the video chip set or the ram. Memtest86 should show errors if there is a problem with ram.
