Replying to the Anonymous dude who posted on Jan 21st....

My SV25 did the same thing, its not the power supply, its not temperature, its not memory... its the capacitors on the motherboard. If you take it apart and look at the FV25 motherboard you will see 5 medium sized capacitors dotted around that have raised tops and possible brown marks on the caps.

You probably also noticed some very high-pitched whistling in its dying moments. If you have a dog, it would have noticed it for you =)

Anyway, My SV25 had done all this and then died completely not POSTing at all. I got the capacitors replaced and now it just fires up, 100% stability like when it was new.

The capacitor problem is one that affects Shuttle and Abit - boards manufactured within a certain period were supplied with faulty capacitors that disintegrated after about 10-12 months.

Big fans are quieter are quieter (lower noise frequency), but move more air. And an 80mm fan at the back which blows air IN, right over the CPU fans. . All the fans have some voltage adjustment to reduce their speed. I also put in a Zalman PS. The P3-800\'s run at 35 degrees

The SV24 was more difficult, because of the space constraints. I did get an 80mm fan on the CPU (Celeron-700). I removed the PS fan (after trying several small, but still noisy, fans). I put a 60mm exhaust fan at the rear, with the speed reduced. IN order to prevent the PS from burning up, something had to give. It was the CD-Rom. These things draw current and produce a lot of heat even when inactive. So I removed it, and put the PS (without a fan) into the CD slot. I use a Fujitsu laptop drive which is placed in the front (very low power, absolutely quiet). I use a Firewire CD.

This computer runs programs fine. The problems are with miscellaneous stuff - the mouse port stopped working, DVD never worked, and now I\'ve lost the CMOS. If I can get the damn thing working well, I\'ll use it as a video recorder.

So I can\'t get into the CMOS when it halts. Does anyone know how to reload the CMOS ?

Thanks

I'm trying to not be a gerbil, but my account information isn't getting to me fast enough.

My SV25 just recently started suddenly restarting under pretty moderate load... I've owned it for a little less than a year and I've had zero problems before this... but suddenly, POOF! It restarts, won't come back up, when it comes back up won't fully start into Windows 2000...

Now, I've checked the obvious things: the CPU isn't overheating (checked the temp in BIOS and VIA Hardware Monitor), the power supply SEEMS to be giving enough power (checked in BIOS) but I'm not sure... no drivers are causing it, no specific programs... I don't *think* my line needs a voltage conditioner all of a sudden... help!

Right now, I figure the power supply is giving out... seems to be my last refuge from madness... I'm thinking about turning this thing into a paperweight until I can get the scratch to buy another mobo. <sigh>

I tried that more than a year after the inititial purchase. Replaced the 40mm small fan of the PSU with an older Sunon 0.9 watt fan after removing the grill and fitting the fan from the outside of the unit (it just fits!). I also dremmeled the exhaust grilles of the unit and placed a pair fan (Sunon 0.9) on the outside of the PSU (very tight!). This way I would get a constant airflow (in-out). My aim was to reduce noise, but it didn't worked. Two fans are as noisy as the one before; I just get better cooling for the PSU. The rear and CPU fan are fitted with rheostats at the rear of the case and I can always decide upon the best noice/cooling combination. The PSU being the only source of uncontrolled noise, I believe that the best solution would be to find a way to fit an EXTERNAL PSU, but it requires a fanless DC/DC convertor (fitted inside) capable of handling up to 150 watts. Putting very quite (with low CFMs) fans on the PSU runs the risk of overheating and failing. I'm still working on better (quieter!) solutions...

Tip: I couldn't play any DVDs for one year. I thought it was the Combo. It was the allocated memory! Changed it in bios from 8 mb to 16 mb and everything worked great!

I don't know but apparently it draws too much power for my CD-RW and my IBM Deskstar Hard drive. After I disconnect those 2 devices then it will power up. anyone have any ideas?

Does the SV25 support PPGA Celerons, or just FC-PGA? I ask becuase my SV25 won't boot. The fans spin up briefly then stop.

I don't think I would attempt to run the Celeron passively mate. These people are running unstable with active cooling, imagine without it. The only way I see it possible is to make a water cooling mod to the unit. Has anyone attempted this yet?

Anonymous Gerbil: what fans are you running in your system?? Just wondering as I'm, just about to recieve a SV24 with a Celeron 900 and was wondering if I could run it passively.

Bought a SV24 in Feb 2002. I had it in a closet and in April we had a unseasonably hot day. The PSU just ate itself up. I emailed Shuttle and got this back:

Send it directly to Shuttle Computer and attention to Tech Support Dept.

Phil
Shuttle Computer Group
Technical Support Dept.
939 Radecki Court
Industry CA 91748
(626)820-9000 ex.204, 205 ,206

I jerked the PSU and sent it off and shortly thereafter a new unit came.

The new unit ran fine until October when, after 72 days of continuous uptime, I experienced several spontaneous reboots while trying to upgrade to Mandrake 9.0. Ever since the upgrade intense usage (ie running the cdrom continuously or copying a large number of files from the HD to an external firewire connected drive) has caused similar spontaneous reboots. Lm_sensor tells me that I'm not running especially hot so I can only surmise that I'm losing my second PSU, or I've got bad caps brewing on the board.

Ack...

I\'ve sent an email to Shuttle - still haven\'t received a response. Got a good email address for me? I\'d be happy to buy one from them, but they say on their website that they don\'t sell direct to the public. So... what the hell are customers supposed to do? No one in the US appears to carry this PSU replacement, Shuttle won\'t sell direct to it\'s consumers, and the nearest site you can buy one from is in the UK, and their site shows the PSU as Out of Stock - so it\'s backordered to them too!

This is a horrible situation and to see Shuttle doing nothing about it is worse still. Obviously, there is a problem with the SV24/25 PSUs, yet Shuttle is doing NOTHING to appease their customers. For the price you pay for this unit, you should at least be able to BUY a replacement PSU.

</rant>

I was able to get an RMA from Shuttle's tech support in CA. 28 days later, I got a new PSU. Just tell them the PSU is not kicking out the correct amount of voltage.

Is the UK the only place to obtain a replacement?

Any other ideas (other than scrapping the case and going with a standard case)?

adv<thanks>ance

tiger direct also send me the wrong celeron processor for my shuttle cube. not to mention the first board itself was bad an had to be replaced before i could figure out that they had sent me the wrong chip. not bad huh? i do not buy anything online anymore except through ingram micro

I am still having problems with the sound of my SV24. There has been no luck finding a good fan replacement for both the case fan and ps fan in the US. I am running out of ideas. Can someone direct me somewhere in the US where I can get a 40x40x10, or the case fan for the back? Also... if you have any experience making the SV24 super quiet, please email me at metasparks@hotmail.com. Thanks.

P.S. For that person having problems with DVD playback, I have not had any. It might be the processor that is holding you back. I recommend setting back some of the Windows XP services you don't need to free up memory resources. Also try repartitioning your drive where you have on logical drive that holds a static page file double the amount of ram you have (I.E, I have a logical D: that has 1.5 gb, with a 1.4gb page file [since I have 768mb ram]). If you have any questions, feel free to email.

I am not computer savy, but I get the feeling that the ATI AIW does not do much to help the DVD play back. I get very jerky DVD play back. Any suggestions ?

As for noise, I have some tips.
Some people mumble about changing fans, or using 7 Volts.
Well, I thought, that using 7 volts might prevent the
fan speed data from appearing so I merely operate the stock
CPU fan on 5 Volts, and I removed the Pwr supply fan from the case. I chopped out the stamped metal grill on the power supply case, then I mounted an external 5 volt fan on the outside of the power supply.
The only sound I hear is the cabinet fan, and a little of the fan on the AIW. It is pretty quiet now.

But back to my main concern, is DVD playback quality dependent solely upon the CPU speed or will the AIW help, if set up correctly ?

That same PSU question has been bugging me too. It has been starting to make a really loud noise. I found that propping up the PSU fan corner of the case about an 1" helps to lower the noise a bit but that noise still comes back with a vengance every now and then. I'm afraid it'll overheat and start a fire if I leave it unattended. I detached power to the rear fan since I leave the case open at all times. Has anyone tried dremeling the PSU to add an extra hole for another fan?

I bought a few SV25 for clients, the power supplies turn out to be a serious weakness. One just died completely after only two months, two are now making terrible fan noises (not just the standard loud running noise). I RMAed the broken one and ordered a spare from a different source (in the US). The two replacement PSUs both came set for 230 Volts, what's up with that?

Anyone know any PSU alternatives? A good way to make those PSUs quiter and perhaps more stable?

Thanks, Loki

I only ever managed to get Suse 7.2 working by fitting a different graphics card. Later versions might have better support though. Sorry it's a bodge solution...

Where can I get PAPST fans from (I'm in the UK)?

Hey, I was wondering if any of you that have this Shuttle system use the TV-Out regularly? Just a few words on how it performs in regards to image size (is there borders?) and any image tearing would be great. Thanks.

Thanks for the info AG239 -- I bought a black Teac floppy and Im buying a black Plexwriter... might aswell use it..

#237: Do you really need a floppy drive ? Just set your harddisk into the floppy bay, then the zalman flower exactly fits there. I use a Via C3 933 Mhz with Zalman Flower.

Im AG237, just did some measuring... seems theres EXACTLY 1U (~48mm) of space, and Zalman wont fit.. for passive cooling Im going to buy a Thermal right SK-6
(http://www.thermalright.com/sk6.html) and use some arctic 3 thermal compound. Should run my Via C3 as smooth as possible.. Any other thoughts on passive cooling? I ordered a Papst 612FL 60x60x25 (16dB) for the case and a Papst 412FM 40x40x10 (19dB) for the PSU.. What about vibration/harddisk noise? Any suggestions?

Will the Zalman Flower heatsinks fit the Shuttle if you use the harddisk-drawer?
