random reboots on 9800 pro

[DimZiE]

i'm getting random reboots after changing my old 9600 np with a rad 9800 pro. does anybody have this problem ?

the specs are:

Barton 3000+
A gigabyte board dunno the type but the chipset is VIA KT600
2 Kingston PC3200 512MB
2 Seagate 80 GB ATA 133 7200
Powercolor Radeon 9800 Pro 128 MB
1 Sony DVD ROM
1 Asus CDRW
Antec 500 W PSU

i've tried updating BIOS,Drivers, Fastwrites on/off,AGP 4x,8x. to no avail can anyone help ??
i've returned the card twice, and still i'm getting th same problem

What kinda amps do you have on your power supply? I know it's 500W, but not all PSU's are created equally.

 

[DimZiE]

everything seems ok on all rails (+5 -5 +12 -12) CPU is on 1,68v..

sorry it seemed i the mobo was an ECS KT600-A

When a computer starts randomly rebooting on me I first turn to something like the hard drive or the power supply. That would be my guess as to your problem. The PSU should be a good one (Antec makes good stuff), but something might have blown in it. Unplug your connection to your mobo to make sure nothing has fused to it. I had a PSU blow out like that.

I'd be supprised if it was an issue because of the card alone. I think it's probably the power supply, possibly the hard drive. Don't know why they would pick now to kick the bucket, but hey, anything can happen.

So, it's not the card.

Try Motherboard Monitor 5. Use the "sys log" feature. Select the log be written to a text.doc. Set the interval for 1 second.

After it reboots, go back and check the log to see what your voltage rails were doing. If it's the PSU this ought to help you identify it.

Might try running memtest86 overnight to see if your ram is acting up.

I don't use winXP, so I can't be specific here. But I have seen others suggest turning off the feature that causes XP to reboot on a failure. Apparently, that way you can see the error report and perhaps find out what is causing it.

Could be just driver related. Did you use the ATI clean driver tool to remove all traces of ATI drivers before reinstalling them for the 9800 pro?

 

[Fern]

Another thought, how many other things on drawing on the power connector to the 9800p? Might give it it's own molex connector.

 

[DimZiE]

yes i did clean the drivers.. heck i even reinstalled XP. the card is on it's own molex connector (my Antec PSU comes with 6 molex power connector) and all the HSF(xcept for CPU) are connected to another PSU.

can anybody help... i'm getting desperate and i can't rma the mobo coz' it worked fine w/ my other graphic card...

 

[Fern]

I'll sugest the trick with MBM5 again. The 9800p draws a lot more power than the ole 9600. I.e, look to the PSU. Yesterday, you noted your rails look OK, was that from checking in BIOS?. If so, that isn't under load and may not show flucuations as the sys log could.

Also the memtest proggie. Could just be a coincidence that the prob kick-in around the time of changing the gfx card.

With 2 diff 9800p's, a reinstall of XP & drivers and know good-working mobo, may have to look elsewhere for the prob.

Just to make sure your gfx drivers (and chipset drivers) are installed properely, as well as DX 9, have you run the DX diag proggie in windows system tools?

I use this all the time. What I don't understand is that when I run it, it lists the files that were deleted in the top list and the one's not found in the bottom. If run it again immediately, it lists the same ones as being deleted again in the top window. I would expect them to appear in the bottom window as not found

I assume you are not overclocking anything?

After random reboots, check the c:\windows\Minidump folder. If there is a minidump there you may be able to analyze it with the MS Debugging tools, (search for a thread in OS for instruction) but in my experience the errors I found weren't very meaningful (although it is likely they were caused by overclocking and hence seemed totally bogus).

Also, I would try booting with only a minimal number of devices. Like your primary hdd and the 9800 Pro. Your PSU should barely be loaded then. I run a slightly less power-hungry system on a 350w just fine.

 

[DimZiE]

yes i did checked the rails on motherboard monitor 5 while runnin' winamp on the background. and i just finished running memtest on my other system w/ the mem stick from my malfunctioning system... and everything is o.k.

but i just ripped off the hsf from the 9800pro and see that the core is r360. i think i'll try flashing it w/ an XT BIOS..
