No it wont be, this will be a different error.
Basically your video card restarted and crashed the system, and then Windows just says its recovered from a serious error because really a restart with no reason is rather serious...
This could be down to one of two things then, a bad power supply, or overheating on the video card.
Plus with the problems with the mouse, it makes me think its the 1st option, a bad power supply. Though it could be heat as well.
You have any extra fans in your system apart from ones on devices?
I would suggest you get a new power supply, I honestly would. Look around for a 400 or 450 watt minimum power supply.
This way, even though this system probably wouldn't need that much. When you get new parts and such, you can use the same one since you said things are expensive where you live.
This might clear up your problems or not, it depends if it was the power supply which it might be. They are rather easy to set up.
If it helps, place stickers on parts where the power supply was plugged into like for instance mark them on coloured wires which our power supply uses now to remember.
The mouse might even work now, as I'm thinking also with the power supply, the power to the PS/2 port might be stopping because of a power problem since this is the only explanation I can think of for why it would suddenly stop, depending on the mouse used.
You could then get an optical USB mouse and test this, or test a new one before getting a power supply. Though i would seriously think about it.
Just thought i'd give you a few options to help
Hope it doesn't confuse you.
NOTE: Also with your expressions, instead of :] which won't work, try using : ) without the space and : (
