[kelvinblank]

before this thing happened, my power supply malfunctioned and didnt work at all. what i did is i replace a new 400w power supply. my previous power supply is just 235w. now my pc is working but its automatically losing power. what could be the problem? im using ep-8k3a w/ amd athlon xp 1600++ thanks

Welcome to AOA. The 400 watter should be enough if it is of good quality. What PSU did you install?

Is it when you tax it or just any time?

[kelvinblank]

im sorry sir but what is psu? kinda noob bout hardware bleh thanks

edit: by the way, i noticed that when im running Ragnarok Online(a online game) thats the time it will lose power. what could possibly the problem? is it softwarre or hardware? i didnt change anything in my software or settings, i just replace my old 235watts power supply w/ a new 400watts.

PSU=Power Supply Unit

i installed a low class psu. single fan 400watts

[Samuknow]

If you are playing a game when it shuts down, it is likely due the the new power supply not being up to the task. If it is a cheap unit, 400 watts does not always mean 400 watts. You would be better off to spend a little more and qet a quality unit.

so what would you suggest me to do? huhuhuh by the way my friend also bought one of these psu and its working fine. huhuhuh

[Samuknow]

Try running a benchmark program or a stress program. 3D mark or Prime 95
See if it shuts down.

Just because one PSU unit works in one rig does not mean it will work in another. Plus, if it is a cheapie, the chance of it being junk from the get go are more likely.

excuse me what is that programs? what do they do? im totally noob sorry

[Samuknow]

Click on the link in the post above for a download to get you started. This will max out your computer. If is shuts down, the PSU is no good.

ok thanks i'll try. i'll be reporting to you the results hehe

[kelvinblank]

dont know how to use prime95 ahahaha

Use any of these programs to load-up your system:
CPU Burn-in Stress

when i was using the cpu stablity my pc when off again

[danrok]

So, if the CPU was overheating, thermal protection would kill the power instantly.

Or, the power is bad. PSU may be failing or the voltage regulation on the motherboard.

So, check the CPU cooling, try another PSU, and visually check any capacitors on the motherboard - make sure none are leaking or bulging.

[kelvinblank]

actually there are capacitors that are bulging =) i think its on the board. thanks for the help guys. but ill try another psu to verify it.

[MUff1N]

If you have Bulging Capacitors on the Motherboard, it's dead or soon to be dead!!! Capacitors regulate the DC Voltage going to electronic parts on the Motherboard. This can also damage other HW parts too by the voltage not being control properly, or not at all as electricity goes through them. I would replace the Motherboard as soon as possible!
(HW=Hardware)

thanks for the help and advices guys

[cloasters]

Do you have new parts that are working properly? Hope so!

[kelvinblank]

all of my parts are working properly except on running programs like games.
