Power supply prob or?

Had this issue for a long time and have done quite a bit in trouble shooting with no luck. Specs: Epox k9a2+, Geil 512mg (running at 2.7-2.8 volts) XP 2400 stock, IBM 15 gig & Maxtor 30 gig, flappy, Pioneer DVD, Sony 24*32*24 CDRW, Aopen 56k Modem, ATI 9700 non-pro Fortron FSP-350 PSU, 4 stealth case fans. (usb mouse and camera hooked up and printer)

So just about any game test will lock or reboot puter if my FSB is any other than 133 with any Radeon 9500 or 9700 card in. Geforce or Radeon 8500, I can get FSB to 200 with no probs. I tried the 9500 pro 2-9700 non-pros a 9700pro and 9700AIW all with same results. I got the fortron PSU do to thinking a 350w would be enough for my set up am I wrong. I have also tried different sticks, brands and slots for the ram no diff, and ran memtec_86 for 12 hrs at 166 fsb with most aggressive timings and couldn?t make it take an error. So yes I?ve tried all setting in the BIOS to detune but who wants to build their own puter to have to detune it. Any help PLZ.
 
have you tried changing your AGP speed? 4x? 2x? 66mhz? i'm pretty sure the 350w power supply should be adequate for your hardware. i'm running a 350w Antec with 4 hard drives, 2 cdroms, and a barton 2500, and a multitude of other things.
 
The rated power of a PSU isn't everything. It could still be flaky. I have no experience with Fortron, so I can't comment there.

Unplug a few of your system components such as DVD-rom, CD-RW, and one of your hdd's.
 
Fortron's a good PSU manufacturer, and it doesn't seem like you have an extremely power hungry system there. Have you tried reducing the load on your system to test for stability(less sticks of memory, less PCI devices, single HDD, etc)? Also, if you suspect its a PSU problem, monitor the various voltage rails on your system during idle and load, when overclocked and non-overclocked, and see if there's a noticeable difference.

Another thing, you did lock your PCI/AGP to 33/66MHz when overclocking right? That might be the reason why FSB overclocking is causing your system to be flaky, even though then the GF/Radeon 8500 shouldn't work either...but its worth a shot anyway.
