The fuse in my BR 300 ATX power supply has blown, what is its replacement part


You need to replace the fuse and dis connect the power supply to the mother board and turn nit back on and if the fuse blowns again then it is the power supply, that is bad, bou if it blowns only when connected to the mother board, the mother has a bad component on it.

Anytime i power my computer. it ask me for password. I forgotten the password. When i try guessing the password, it goes off on the 3rd guess.


hi,

you can solve the problem easily,

first unplug the power supply to the cabinet (CPU). you need to open the case of the CPU (the cabinet) , for that unscrew the screws at the left side of your cabinet, now you can see the motherboard, in it there is a small button sized battery called the CMOS battery which powers the PROM, in which the password is stored. you need to take out the battery from the motherboard and put it back after 2 minutes. cover the cabinet. start the system, it should work fine.(no need for any password)

by removing and re-inserting the CMOS battery you actually erases any user customization in the BIOS, and loads it with the defaults

Computer suddenly dies intermittently


Hi..

In this case when it is always beeping during the computer is on. You need to check the memory stick if it is not faulty. Remove the memory stick and clean it from dust. Clean also the memory slot and reinsert the memory stick. If the problem still occur try to use the other memory slot.

Good luck!

Concecrning the previous post, thank you so much that did indeed enlighten me a little although now i am thinking perhaps the power supply doesnt agree with the board. i did as you said and also unhooked...


That connector is the CPU power connector. Plugging it in and having the problem surface signifies either the CPU is blown, or there is a short in the power lead. The only way to make sure is to either try a different CPU, or connect your power supply to another motherboard.

PC dead. Replaced power supply. No lights. No nothing.


When that happens it is usually the motherboard.

To test parts you need a benchmark.

PSU can be tested using a multimeter.

Motherboard is tested using a tester like this one: PCI Test Card, PC Analyzer, Motherboard Test Card
Ram and CPU (CPU sometimes get damaged) are usually not damaged by this kind of problems, they can be tested mounting them on a working motherboard. For the RAM we also use a RAM tester that costs about $200.

Ensure also that the switch contacts to new motherboard are installed properly. A technician can test cabinet power switch using a multimeter, or carefully bridging with a screwdriver the switch on contacts on motherboard (do not do this unless you are sure about what you are doing)

Test the new PSU on a different socket, when a PSU blows , it may damage the main socket.

Also remember that new power supply units have two connectors. The big rectangular main one (24 pin) and a smaller 4 pins squared one.

As an home user you may not have access to testing equipment, therefore my suggestion is.

Ensure you are using the right PSU.

Ensure that the motherboard is connected to power switch.

Test the new PSU with a multimeter.

Examine the motherboard for blown or leaking components and burnt areas.

If you do not find anything, but the mainboard is still not working, then buy a motherboard-cpu bundle compatible with the PSU that you bought and assemble a new system inside the old cabinet.
