If there is a BIOS corruption or failure, as it seems from your post, the ONLY option is to replace the motherboard. If this is still in warranty contact Dell support.

i didnt really sure what happen... either i got malware attack my bios or other else, i use both Windows Defender + AVG internet security
now DELL bios post screen full random character...
and i also get Floppy disk fail .. alert audio cable not connected
what bad for me is that, i moved to another country last year, so i dont know if dell want to cover warranty in the country i stay now
i think this issue can be fixed, if i can reflash the bios again
trying to boot from cd but not working... i can boot from system rescue CD though

Try to clear the BIOS again. Remove the battery for at least 30 minutes and disconnect the PC from the AC power then push in on the power switch for about 30 sectonds.
It appears some parts of it are working. Can you get into the BIOS (F2) ? You can then fix the Floppy disk error by disabling it (it was enabled by the BIOS reset). The audio cable alert is another issue. There are big threads with that problem - it happens on systems that do not have a BIOS problem.
Looking at the BIOS installation instructions, there is nothing about flashing the BIOS from Disc, the instructions are only for flashing from Windows.

after few test..
i finally starting to think that the one broke is vga card...
Because i see lines when entering windows.... although i can enter windows, but sometimes the windows just crash
then after few tries bios reflash, i figure out that the bios sometimes can detect and sometimes cant... i dunno why, but at least i can reflash bios
i will grab new VGA in few days and update the result
as the current that come with my xps730 is 9800GT

That was going to be my next suggestion - the video card. But, before you buy a new one, Reseat the Video card and see if that helps. Reseat - with the PC powered off, open the case and remove the Video card, then reinstall it. See if that helps.

thanks for the help fireberd
i tried by reseating the VGA and plugging to another available PCIe but not works
so i grab a new VGA (Gigabyte ATI 5850) and it solve the problem (random character on bios)
While its most obvious that the VGA die, i wonder if there bug in bios too, why i am telling this is because my Asus Xonar D2X also got issue, its Eeprom flashed (which i need to reflash using tools that i got from http://www.alsa-project.org/main/index.php/Xonar_EEPROM_Failure)
I dont know why this happen too, maybe just coincidence
Beside VGA and Xonar issue, there no other issue atm (well there minor system crash in windows, seems because some registery left over from nvidia driver) the system back to normal now
What i learn is, its enuf for me to use nvidia parts in my pc... at least for while... nvidia chipset, vga and their driver got many issues...
next time i get my pc, it will intel with ATI inside :emotion-2:
