KV7-V power supply

I think my power supply has fried. The computer was on and suddenly shut down. I let it set for awhile and it started back up but shut down after about 30min withan electical burn smell. I want to replace it but am confused. The old one is a POWMAX, ATX Switching Power Source @ 400watts. What would be a good replacement and maybe with a little more power?

Re: KV7-V power supply

Thanks sandrew.  The power connection was fine.  I ordered a new power supply 500w and have just finished installing it.  And it is running fine.

Follow the power cable from the PSU to the motherboard and see if the 21 connection has melted to the motherboard. You are better getting a 500W silent type, but it depends on the peripherals you have installed, try for various makes.

Shuts down


This is a typical symptom of a failing power supply. Replace your power supply and see if the problem still persists.

Please notify me should you need any further assistance.

I have an old gateway PC Model # S- 5215-D. When powering on computer the drive starts to spin up and then stops, leaving just the blue light on. Note the fan in front and back also stop. However if you...

Have you tried taking it apart and cleaning the inside of your tower? That worked when my old Dell would do that, but eventually it quit for good, sounds tired, maybe have it serviced by expert.

I was running a virus check, asked what to do, I said fix, computer shut down and alarm buzzer came on. now I don't get a boot sound

With the system shut down, unplug the power cable from the power supply. Open you're case and pull the memory from the system wait a minute than reseat the memory. Re-connect the power cable to the power supply. Try booting the system and enter the bios menu. (Pulling the memory will clear any memory resident virus). This has nothing to do with the alarm buzzer sound you heard. Typically the alarm sound is generated by the CPU. It's an audible warning that the CPU is over-heating. The CPU will shut down you're system so as not to damage the motherboard and CPU. (Suggest you check the CPU fan for dust build-up. Use canned air to help remove any build-up. You can also use a clean paint brush to help remove any dust from under each CPU fan blade.
It's also possible that the CPU fan is running far too slow and may need to be replaced.
See page 3-23 in you're user manual.
3-8. PC Health Status.

Open the link provided below for a new heat-sink and fan assembly for a socket 462;
If the CPU fan and heat-sink assembly seems clean it is also possible that the thermal grease / thermal tape between the heat-sink and CPU is too old and needs to be replaced. (Save this check for last).

Sounds like a software clash. I would recommend formatting your hard rive and reload your operating system, obviously backing up your files first

Keeps turning off

Sounds like a hardware failure. Possilbly the motherboard, more than likely, the power supply.
But then - maybe neither.
Shut it off completely, once you restart, start hitting the F8 key ( once a second ) until you see the " Safe Mode" choices screen. Drop down and select the " Last known Good Configuration" option and hit enter.
If this doesnt work, try the same proceedures ( restart - F8 ) but this time select safe mode - at the top of the list.
If you sucessfully boot in safe mode, you have a system file problem that could be virus related, file table corruptions or registry problems or all combined.
