Strangest issue..

[ATI RADEON 8500]

I recently built a new computer and transfered my ATI 9800 AIW PRO from my old system to the new one. The issue is that I could't set the eye candy to high without it developing artifacts on my old system. I thought the video card was defective.. So when I used it on the new system and cranked the eye candy to max and everything worked perfectly..

Video card: ATI Radeon 9800 AIW PRO (Stock speed)

Old system
ECS k7s5a
Athlon 1900+ Palmino core (Stock speed)
1.5gb PC2600 ram

New system
ASROCK 939 Dual- SATA2
Athlon 3000+ Vience core @ 9x270 (2.44 GHZ)
1gb PC3200 ram

Both use same kind of case with 2x 25x120mm Sunon fan

Did you try contacting ECS? I've had experiences with both nVidia and ATI where the cards have gone quirky with the motherboard I loaded them in. Mobo mfgs sometimes don't test as thoroughly with outside hardware as they do with 'last 10' firmware revisions on card-x.
Did you try older and newer video revisions?
Does your old box have a sufficient enough psu to support the 9800's draw with the other components installed?

I only have 3 video cards. 9800 AIW PRO, 9500 128 MB non pro, tnt 2 m64. I did test with Both radeons and it did have problem with both of those cards.

I'm not quite sure about the revision thing..

Here extactaly what my old system had.

Old system
ECS k7s5a
Athlon 1900+ Palmino core (Stock speed)
1.5gb PC2600 ram (512+1gb) and happened with 512+256 too.
80 gig WD 7200 rpm 8 mb cache
80 gig Maxtor 5400 rpm
CD-RW rom
DVD rom
Creative sound blaster live 5.1
usb 2.0 pci card
2x 120x25 sunon fan

Could it be caused by my cpu? In my old case it's much hotter inside than the new case. Old cpu idle at 42c while new case idle at 32c.. While playing games old cpu goes over 52c and new cpu overclocked gotes to 48c.
350 watt Antec smart power.

'revision thing' ...The video drivers. Are you uninstalling them and installing new drivers properly? Have you tested older drivers and newer ones?

The heat 'may' have a factor in it, but initially as you said both cards have issues with the older machine, I'd look at your drivers' revisions and proper uninstall / install routines first. You can find the foolproof ways through the 'best of''s here as you know, or via the ATI drivers' readme's.

The psu draw 'may' be pushing the envelope on maximum-rated. Did you run your config through http://www.jscustompcs.com/power_supply/ ? Unless I clicked wrong, your listed setup is right at 350W....usually a minimum of 25-50W buffer is recommended.

You've got 2 potential avenues ...I'd start with the drivers as they're free, and only cost the time it takes to play around with them.
