I'm not sure of the problem, so I wasn't sure where to post this... First off, specs on the computer:
Windows NT 4, with Service Pack 6
Dual P3 (800mhz)
256 ram (pc100)
2 DPS cards (PCI)
1 Amber card (PCI)
1 Sound card (PCI)
1 Video card (dual-monitor, AGP)
1 NIC (ISA)
2 HDs, 1 SCSI, 1 IDE
A couple of weeks ago the computer started spontaneously turning off... Just like unplugging the thing. Usually afterwords I have to hit the power supply switch and the power switch several times before it'll come back on again. At first I thought it was heat, so I pulled off the case and let it run. After it crashed I felt around inside but nothing was running hot, not even the power supply.
It will only do this when I'm in either Photoshop or Illustrator, both Adobe graphics programs. I tried unistalling and then reinstalling Photoshop, but no go. Photoshop is a memory hog, so I maxed out my memory with other non-Adobe programs, and it didn't crash. I maxed out the processors (by making a huge render in 3D Studio Max) and it didn't crash. I replaced the RAM, re-seated all the PCI, AGP, and ISA slots, and it still turns off. I keep thinking it's hardware because of it just turning off and staying off for a while, but it only does it while in Photoshop... As a last resort I'll reinstall Windows, which I really don't want to do.
The PSU is about 6 months old, and I doubt it's the problem since even maxing out the processors and the memory it still wouldn't crash. I've tried everything I know to try, there must be something I'm missing. Let me know about any questions you have...
