REBOOTS (NO BSOD, automatic restart disable)

[Calchaqui]

Drives me crazy, Windows Xp SP3 default Directx9, FX5600, runs fine, reboots at 1 second of with 3dmark03, no BSOD, just reboots or PSU go to sleep mode, change PSU, same thing but just reboots (no sleep mode). Question is, can a SOFTWARE/DRIVER problem reboots like that? not freeze/BSOD, 5v line is a bit lower 4.76v-4.85 with BOTH psu

Are you running a mobo that gets cpu voltage from the 5 volt line or a mobo that uses 12 volts to power the cpu? Also the PSU maybe to weak for the GPU causing the restart. You can change how the computer reacts to crashes in the advance settings. Change to diplay error code instead of restarting pc.

Need to determine if it is a hardware or software problem first. What are you using to read those voltages from? Best use a vom analog or digital taken from a free molex connector.

Does it reboot when running a Linux LiveCD or some other OS?

What motherboard model is it?

That was going to be my question. Board model? CPU? Cap brands/condition? You left way too many important details out.

Sorry guys, it's old hardware so I'm ashame of it. Mobo takes power to VIO and Vcore from 5v line. It's an Asus p2b with a Cumine 1.13Ghz, I've found it's not an AGP problem, Microsoft memory (booteable memtest clone) show same symptons REBOOT or go to sleep mode. Board is full of sanyo and rubycon caps. It always creash at test n4 using cache, disabling cpu cache didnt help, this's the second psu (codegen with 30A on 5v rail)

That's the first thing I do when install WinXp.

Are you overclocking the memory bus? The P2B is a 100Mhz bus. Also Coppermine CPUs are not supported unless you do the mods for core volts below 2.0V

Last time this happened to me it was in and AMD AM3+ system and BIOS update fixed it.

A bios update will not fix his problem. Without hardware modding running Coppermines on that board will not work properly if at all. He is pushing that board to its limits as far as the OS is concerned and the GPU card.

Thanks God this guy had the same problem: http://www.tomshardware.com/forum/14...g-test-memtest

He found that p2b is very picky about slotket. In particular, my slotket (Soyo SY370 recapped) was rebooting (or putting psu in sleep mode) at test 6 microsoft mem. test using cache. I know nobody will care about this, but perhaps it helps some retro hardware guy. Thanx guys.

Glad to see you found that info, will bookmark it. I have some Asus P2B-F and P3B-f, do not know if effected by that problem or not.

My P2B-F behave so weird, it didnt reboot, it freezed twice per month with the Soyo Slotket. P3B-F was a more cleaner design, almost bug-free. P2B-F has a very weak 5v line, tried 4 psus 30A+ and never go higher than 4.76 at IDLE.

Google search for "photoshop bug". The mods should fix the quirkyness of the P2B-F and P3B-F mobos.

I know that, but unfortunately all links and cache about p2b-f vtt caps for photoshop bug are plain dead, including using TIMEBACKMACHINE site, there is a japanese guy who made custom mods to the p2b-f (i think this guy's a pro), there is also a p3v4x mod (apply to p2b-f) soldering a bridge from 3.3v atx pin to the coil of Vio VRM.

post it , if you got the p2b-f photoshop bug vtt correction
