Re: Are these caps bad?
Well, yesterday I plugged in a different, reliable power supply which seemed to fix the problem. I thought all was going well so I ran Prime95 for 26 hours to make sure everything was OK, and the test passed flawlessly.
After turning off the computer and moving it to where I finally want it, I turn it back on, and lo and behold, no POST. But it ran Prime95's torture test fine...any suggestions?
Thanks....

Re: Are these caps bad?
Seems like even when it's cool, the board still won't boot. Guess there's more caps to replace, huh?
For what it's worth, if the machine is on, it's stable (from what short testing I've done), and all warm starts (reboots) work perfectly. It's just the cold start that's giving it problems. Does that narrow down the problem?Leave a comment:

Re: Are these caps bad?
Well, I've managed to replace most of the larger caps on the board that I could easily source. There's still a handful left that haven't been replaced. I'm looking for them as we speak.
Good news: The board will boot again!
Bad news: Once the system gets sufficiently warm, the board will refuse to boot until it cools down a little bit. And by sufficiently warm, I mean ~38*C or so for the CPU and power temperatures.
Is the problem getting the motherboard to POST when it's warmer possibly due to more bad capacitors...Leave a comment:

Re: Are these caps bad?
Basically, the safest way is to replace all the caps with 16V caps with the same uF value...?
Or should I replace those with the slight bulge and proceed from there?...Leave a comment:

Re: Are these caps bad?
Looks like I have to replace every single cap then.

Re: Are these caps bad?
rofl. I admit it. I read too fast.
There are 10V and 25V both of which are G-Luxon...I can't seem to find any 16V caps, but basically, every cap that's not OST is G-Luxon.Leave a comment:

Re: Are these caps bad?
The MBZ are of the same rating as the OST...3300uF and 6.3V.Leave a comment:

Re: Are these caps bad?
Hey Wizard,
The board will sometimes POST, more often not, and when it does POST, I'll get random BSODs.
Yes, I've tried the PSU, RAM, and video card on another system and all work perfectly. I've cleaned off the thermal grease on the heatsink and reseated the CPU with new thermal compound to no avail.
And yes, it's an ECS motherboard.
I just wanted a cheap solution to fixing this rig. $20 for some new caps is better than buying a new motherboard for an outdated (2.4ghz, single core) CPU. And...

Are these caps bad?
I have a few pictures of my motherboard that crapped out about half a year ago. The CPU is still good and so is the RAM. If I could get replacement caps and everything done for ~$15-20, I think it'd be worth it.
Here are some pictures of the caps I think might be bad. I don't want to replace the other ones, even though they're of inferior quality, if I don't have to.
There are no obvious leaks, but the tops are slightly bulged.

Re: Bad capacitor? ECS P4VXASD2+ motherboard.
Unfortunately for the existing motherboard, it seems like I can get a new CPU/motherboard combination for only $80.
I don't have any soldering tools and to buy those would be much more than just replacing everything out. Having it re-capped by a professional might be at least $40-50 and I'd still be stuck with the old CPU.Leave a comment:

Re: Bad capacitor? ECS P4VXASD2+ motherboard.
From what I see, some of the tall ones that seem to be slightly bulging at the top are OST, and the green ones that look fine are G-LUXON.
I've switched out the PSU with one I know is good since it was powering another computer. Plus, it seems almost impossible to take the case off my existing PSU. I tried for at least 10 minutes the other day.
It's a Compaq model PSU, 250W. Nothing else to indicate the actual manufacture before Compaq re-badged it...there's Compaq parts and model numbers. And it's Made...Leave a comment:

Bad capacitor? ECS P4VXASD2+ motherboard.
Bad capacitor? ECS P4VXASD2+ motherboard.
History:
Over the past 6 months, my computer has had increasing number of BSODs, freezes, and reboots. This past weekend, the computer froze while I was away from my desk. For the 4-5 reboots I did, I kept encountering BSODs before the Windows logon screen appeared. Finally, the computer refused to start up. No POST beeps, blank screen, CPU fan powered up normally, so did the floppy drive, DVD-RW drive, and hard drive.
I did manage to get it to start to the Windows logon screen once since then after repeated reboots,...Last edited by epikcap; 06-09-2008, 12:04 PM.
