keyboard is being stupid

ok, so my specs are -
toshiba tecra s2
intel m centrino 1.73 gHz
1x512 MB ram
nVidia geforce 6600

the cause -
i decided to clean my laptop because toshiba has crappy cooling and it clogs up and overheats. i used a site called iris(something i forgot what).com and it had complete instructions on how to take apart the machine. I took it apart, cleaned it by using a Q-tip on the fan and by using a compressed air thingy to blow all the dust out of everywhere.

the problem -
i put it back together, but what happened was i switched 2 screws by accident, so instead of having 2 3mm screws in their holes i have 2 5mm screws and visa versa (random info but maybe thats it i dunno). then, i power it on and it beeps at me. first it was 3 short 4 short 3 short. but either i misheard or there is no such thing on earth. i checked the keyboard, ram, mouse, vga cables.....everything. turned it back on and it gives me the classic 3 long beeps - no keyboard. i've tried a lot of things - hooked up a ps2 keyboard through an adapter into a usb port, plugged the wire in backwards, cleaned the keyboard with the air thing repeatedly, checked for jammed keys...nothing works

and i probably wont have any financial support cuz my dad says its my fault (and it is) so help would be very much appreciated

please and thank you,
a soul in distress

 

First check the BIOS and see if there is an option to display a diagnostic screen on boot-up. If there is, this should tell you where the problem is. Then check the keyboard again to make sure no keys are stuck down. This can cause beeping.

Finally, I would suggest that you dismantle the computer like you did before and reassemble it again, giving close attention to making sure that everything is connected properly and connectors are the right way round.

i would check the bios if only it showed anything on the screen.
however, the screen only starts displaying things after the post.
either that, or something's wrong with the screen (oh no)
i will check on another computer with the keyboard disconnected and see what happens.
will resetting the bios or using a usb keyboard help?

 

I know you probably don't want to do this but you should consider taking the computer apart and putting it back together again. You said you messed up the placement of some screws - maybe something else is loose or not connected right.
