What OS are you using?

What Video card are you using?

 

[cirocorby]

windows XP home and using ATI Radion 9700 Sapphire video card

That board is built for DDR400 (PC3200) memory modules, so I suspect that your PC2700 memory modules are contributing to the problem. It could also be insufficient power from the power supply, or poor-quality power from a poor-quality power supply... what power supply do you have?

Update: after reading the manual, I think I was wrong about needing PC3200 memory modules... it appears that it can run an 800MHz-based CPU with PC2100 or PC2700. The manual does mention that installing Service Pack 1 for WindowsXP is recommended... if you haven't done that yet, it sounds like an easy thing to try

You may want to FLASH the BIOS with the latest update
if you haven't done so already.

P4C800 Deluxe BIOS v1006

While it is not specfic to WinXP, there is a issue with ATI 9700
video cards becoming unstable under Win2k (see no reason why it wouldn't apply here)
Enabling HyperThreading probably just makes the issue worse.

thanks for your replys. I have a 400watt silent power supply, XP with sp1 home pack os installed up dated bios 1006 and still having the same hassels any other ideas? thank....... if the Ati card has an issue whats the solution? the issue with the video card i thought was with the ATI Radeon 9700 PRO model only??? i have the non pro model

One thing i just have noticed is when firing up my pc i get 2 beeps( the manual says Parity error) I dont know what this is or what it means do you have any Idea? & i have noticed when hyper threading is on the computer is only unstable when on line (Optuscable) it crashes and a blue screan of death . It closes down so fast i carnt get the error code the sytem gives me.....................

First be sure that you flashed the BIOS using the P4C81006.exe file and not any of the BIOS update procedures as recommended on the download site.

If you are running standard change it to manual and set it as follows:
200fsb
ratio=320 (5:4 really)

You should be able to leave the rest at default.

It sounds to me like your BIOS may be picking up your memory timings
to be Auto=400 which may not happen for your PC2700 (DDR333).

still the same hassels its driving me mad! set as you have mentioned but still crashes with hyper inabled! and only still when internet explorer is working.................. i have cleared the c-mos to defult, taken out all other hardwear like internal modem tv card, unistalled all drivers etc , my next thing is to reformat one more time and start again and still getting 2 beeps on start up. (parity error) what the hell is parity error mean? one starts to think one should have perchased gigabite board or MSI............... less hassels

 

[cirocorby]

new updated bios 1007.002 beta and guess what still no luck still the same hassels i just wished i lived near were these boards were made so i could ramm it up the back side of the person responsible for making such a crap product! want hassels buy Asus!.......... i have never sean such a bad mobo in my life and i have had the many many motherboards to play with ...................but this one mmmmmmmmmmmmm

What brand and model is your power supply? Antec, Enermax, Zalman...?
