Specs: Windows Vista
i was on my computer today and my brother and mother told me my computer fan has been coming on more often than before and than maybe i shoulod clear out dust .
So i opened it up and disconnected all my cords then disconnected all the power cables inside so i could clear out the dust and then cleaned out the dust.
Then i connected everything back together exactly as they were closed it up plugged all my cords in and started it up, however, the computer came on (lights came on as well as the fans) but thats all no booting sounds and nothing on my monitor

what can i do to fix it?

My computers used to do that sometimes... try taking things out
one by one or just take everything and put it back in (what i
always did when blowing dust out)... like the Ram - CPU - GFX
card etc... and see if it that fixes it (whilst doing that blowing out
the excess dust that may have fallen in between slots and pins)

Either you didn't reconnect something correctly or you did something 'non-smart' such as using a vacuum on your motherboard & other components. Vacuuming causes a static charge to build up which can in turn, fry the electronics. Unless your system was extremely dirty, all you needed to do was give it a good blast with compressed air....disconnecting anything is usually unnecessary.

Then you probably either connected the cables wrong or you dislodged something. Try reseating all cables cards and RAM.

Of course even just touching the components inside the case can release a static discharge. Especially now that the air is dryer in winter.

If you dislodged the heatsink then you may need to remove it clean both surfaces and apply new thermal compound before refitting the heatsink.

If you are not getting any beeps or video you may have disturbed the RAM sticks. Remove them and re-insert.
