Hello,

I am experiencing some strange behaviors from my computer. I have noticed that undel heavy load like FarCry, Battlefield2 and such, my PC is halting like 20-30 sec before working again.

This is happening since I have swapped my V1.02 P4C800-E to a 2.00 P4C800-E. At the same time, I did swap my old PSU (Enermax EG461P-VE) for the one in my sig, which is supposed to be even better. Also, when I installed my new motherboard, I immediately flash the BIOS to 1021. Before I made all these changes, my PC was rock stable at 3.75GHz at default voltage. You may ask, "why the hell have you swapped all this if it was stable?"... Well, I sold my old parts to a friend so that he can set up a gaming machine for rather cheap so at the same time, I did pick up "better parts". Right now, I have these problems. I cannot locate for sure where the problem comes from. I do know that if I put back my CPU at 3.75GHz, I get some error with ATi VPU recover and I am forced to put the voltage up to 1.60V.

The thing that annoys me much is that the PC is halting for unknown reasons, even if I put all back to default. I did even a clean reformat with no luck.

Any clue? I definately neep some help :(

I did notice 2 things :

All voltage rails are a lot lower than with my older motherboard like

+12V is 11.7 / 11.8V
+3.3V is 3.2
+5V is 4.9

Before, they were all above their respective rating.

Also, the temperature are a lot higher. Idle, my PC was like 26ºC. Now, it is 33ºC. I don't know if it is due to motherboard revision...

The thing I can do for now is to test the PSU in another machine to see if I get higher readings. Also, I can revert back to BIOS 1019 which has proven to be stable as hell.

almost sounds like the video card is overheating.

have you run prime95 and memtest?

Not yet. I do not experience artifacting so far.. My side panel is removed. I will try memtest just to make sure this is not related to memory.

Thanks for the info,

I have just run a stance of memtest 3.2 and I get a lot of errors only after 10 minutes, almost 600 errors. Most of them were on test #7.

I think I will have to memtest each stick separately to see which one is dead..
