In the past 2 or 3 weeks my computer has been randomly freezing or getting the message, No Signal...I then have to restart my computer all the way.
This happens A LOT. I can barely stand using the computer anymore. It happens when i play games, browsing the internet, and sometimes even when the computer isnt being used it freezes. Anyone have a clue whats wrong?
Also, i can move the mouse around when it freezes but nothing else works and when it says No Signal nothing works. Im not that good with computers so i would need specific instructions if anyone has an idea

no signal is your monitor telling you that it is not receiving a signal from your videocard

off hand, I would say you have a failing power supply. Do you have a second computer you could pull a power supply from to test

Yes i have 3 computers, this one and the same exact type and another computer that doesnt work atm. Im not sure how to mess with that stuff though but i will mention it to my brother. Do you think the failing power supply has to do with the computer freezing as well as no signals?

it is a good possibility

Removing a power supply is very simple....4 screws hold it in the case, and the power supply is connected to the motherboard by a 20 or 24 pin plastic connected that is probably latched. Depressed the latch and pull. It may also be connected by a second 4-pin connector with a latch.

Each harddrive and cd-rom is connected by a 4 pin plastic connector which is simply pulled out--a floppy drive is connected by a smaller 4-pin connector which needs to be lifted slightly to remove as it latches on the bottom

Sometimes, a similar connector is hooked up to the videocard

Other than the four screws, it is all hands only

Make sure to touch a part of the metal case before touching anything inside the case to avoid static shock damage to componants

A power supply should take more than 5 minutes to swap out.
