Re: Bad Capacitors or PSU Problem?
This power supply IS brand new, and its not a cheap one. Its a Hiper Type R 580w PSU, but the system still shuts down at random times, be it during use, or during start up....Leave a comment:

Re: Bad Capacitors or PSU Problem?
I'm in California
1) Yes, it happens WHILE starting sometimes. So definitely regardless of cold or hot.
2) Yes, it spends a good amount of time powered up, but any decent computer should be able to handle that...
3) Computer born at the end of 2003 (if thats what you were asking)
Yes, its getting progressively worse. Now it is almost guaranteed that when i want to use it. It will shut off at least once when im trying to boot or immediately afterward, and then possibly...Leave a comment:

Re: Bad Capacitors or PSU Problem?
but to have my old PSUs caps bad, AND the one i just bought?
.... i just have horrible luck? Earlier in the thread, people said my PSU caps looked fine...
and whats an ESR meter, and where do i get one?Leave a comment:

Re: Bad Capacitors or PSU Problem?
So I ran the BurnK7 for about 10 hours with no problems, then the next day for about 18 hours and then it shut off. I feel more like it was probably just time to shut off again though, as it had been running for at least 4 days by that point without shutting off, rather than having been because of whatever the program was doing... I then ran BurnMMX the next day for at least 10 hours, also failing to cause a problem. In the days following though, it has gotten worse again, and its now shutting off AT LEAST once a day, or as was the case yesterday,...Leave a comment:

Re: Bad Capacitors or PSU Problem?
Well, i took the reccurance of the problem after the installation of the new PSU as a sign that the problem was still there.... so no, i dont think so. It hasnt shut down again since, but I havent had a chance to do the burnk7 and such on it yet, as i've been busy with work. If it was the PSU though, why would it have had a power cut once the new one was installed?...Leave a comment:

Re: Bad Capacitors or PSU Problem?
Ok, sorry for the bump of a really really old thread, but theres finally something new here. I finally had the extra cash to pick up another PSU, and after installing it, the problem persisted almost imediately. My computer got through booting, and was opening startup windows programs, and boom, power loss. This obviously rules out the PSU, so is it pretty definite that I need to replace my Mobo capacitors?Leave a comment:

Re: Bad Capacitors or PSU Problem?
well, i dont really have an alternate power supply i can put in the computer to see if thats the problem, so i cant really see if that would eliminate it (and i definitely havent ruled out the PSU). The power draw doesnt seem to be an issue if running the BURNK7 for a few hours didnt do anything. I guess i'll have to continue my search for a temporary test PSU if theres nothing else i can do to identify the problem component.
btw, thanks a ton for all your help here. Keeps me from feeling like just throwing the whole thing...Leave a comment:

Re: Bad Capacitors or PSU Problem?
can anybody help me with running this test?...Leave a comment:

Re: Bad Capacitors or PSU Problem?
Yes, my cpu has HT, and i ran it for awhile without any shutdown. So i guess since you said it should happen almost instantly, its probably not the CPU. I'll have to run the BURNMMX like you suggested, but it has more options than the other tests. What do i set the RAM size to? The default is 64 kB, but it ranges from 2 kB to 64MB.Leave a comment:

Bad Capacitors or PSU Problem?
Yes, the other 50% is System Idle Process. It is using EXACTLY 50% at all times. This is very consistent and the CPU Usage only increases to 51-54%ish if something else is using a little (like 50% BURNK7, 1% taskmgr as i scroll through the processes)....Last edited by saxman285; 04-06-2006, 12:04 PM.Leave a comment:

Re: Bad Capacitors or PSU Problem?
How long should the BURNK7.exe and BURNMMX.exe be run for to expect to have them cause a powercut?
Also, when running BURNK7.exe, the task manager shows only a 50% cpu usage. Am i doing something wrong so it isnt stressing the cpu like it should?Leave a comment:

Re: Bad Capacitors or PSU Problem?
18 hours..... you've got to be joking me.
This is gonna show me why my computer shuts off every couple hours, and yet its gonna take 18 to even show an error?
Is that really necessary?Leave a comment:

Re: Bad Capacitors or PSU Problem?
Sorry for the delayed reply, i had a hard time getting the memtest bootdisk to burn properly (and my floppy drive has been messed up forever).
I ran memtest86+ 1.65 for about 3.5 hours and came up with no errors..... im considering that a bad thing only because it still gives no clues as to what the problem with my computer is.

Re: Bad Capacitors or PSU Problem?
ok, im looking at [url]www.memtest.org[/url] and just wondering how i should go about this. Will it create some sort of log that i can post here to get some feedback? or will i need to know how to interpret what it shows me?Re: Bad Capacitors or PSU Problem?<b...t it shows me?Re: Bad Capacitors or PSU Problem?
ok,Leave a comment:

Re: Bad Capacitors or PSU Problem?
hmmm... well all tops seem to be flat, and not bulged on both the PSU caps and those onthe mobo....
I guess i'll have to run those memtests when i get a chance, and maybe that will help....Leave a comment:

Re: Bad Capacitors or PSU Problem?
Ok, well, upon the initial suggestions of the capacitors being a possible culprit to my problem, i thought it was just a motherboard thing. But at your advice, i opened up the PSU and checked it out, and saw huge clumps of what i first thought was dust, but upon closer inspection is actually a hardened white substance. Could be glue i guess, but i dunno why there'd be glue in there. I guess this would be the electrolyte (though the caps arent bulged at all). I took pictures, but my camera doesnt have a macro-focus, so it was hard to get them clear....Leave a comment:

Re: Bad Capacitors or PSU Problem?
I did have a problem when i first ordered the board, which caused it be unable to POST stating "system has failed cpu test". I researched it a lot and found out about the problems with the retention mechanism, and instead of voiding my warranty by scratching down the solder like some suggested, i sent it back to Asus, who attempted once to fix it, then replaced it on a second attempt. Since i got the mobo replaced, however, i havent had that problem.
Yes, as soon as it experiences a loss...Last edited by saxman285; 03-24-2006, 03:47 PM.Leave a comment:

Bad Capacitors or PSU Problem?
My System:
Asus P4C800 Deluxe
Pentium III 3.0Ghz CPU revision C
2x 512MB Samsung PC3200 DDR
Enermax 350W PSU
For reference as to possible power problems, I run a 128MB GeForce FX 5900, a DVD-ROM, a CD-RW, and a 120GB HDD, and other miniscule components.
My problem is that my computer just randomly shuts off. Theres no blue screen, no restart, no shut down, it just turns off. I can be sitting and gaming, and the system will just turn off, or the computer can be sitting idle, running only low-demand background processes, and it will do the...
