Hey there!
Here is my story... Recently I tried to overclock my pc with software called setfsb (software overclocking). I know that it is possible to use bios for this, BUT my stupid intel motherboard (dp35dp) has no such options. So I went to google and found out that there are some "software" overclockers. First I've tried ClockGen, but it had no pll (or generator) for my motherboard, so I've tried latest beta of SetFSB. OK, everything went smooth, SetFSB has this SLG505YC264BT generator. So I cranked up a bit my FSB. Good. System showed me +40herz... So I've tried to up it a bit more... Well... This is when computer got mad at me. Mouse pointer stoped responding (I mean it froze). So first thing I've tried was just restarting computer with reset button, but to my super luck, monitor showed me "no signal" even though motherboard looked as if it was working (fans were spinning, I could open/close my dvdrom, all lighters were green and there were no beeps). So I fired up my laptop for this problem and couldn't find anything. It looks like SetFSB just patches windows to overclock processor, not bios, but I didn't knew what it could be then. So I downloaded this Recovery BIOS Update [DP0326P.BIO] from http://downloadcenter.intel.com/T8C... and burned it to cd. OK, I followed guide (http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm) and for my surprise when cd loaded monitor came back to life showing me boot logo. Then I waited till flashing process went till the end (Computer showed Me "Flash update has completed succesfully"). So after that I've put CMOS jumper back to it's possition in motherboard. At that moment I was happy, because I thought that problem was fixed, but when I powered up my computer after inserting jumper, again there was no signal on the monitor... Tried that again, but no luck: CD boots up flasher and it flashes bios (monitor shows me boot screen for few moments and then flashing process fine), but after restart it is back to "standby" monitor state. Motherboard can't be dead, because it works, and even shows flashing process, but I don't know what it could be then... Any ideas?

Why would you flash the BIOS just because of a failed overclock. How are you flashing? From within WinXP? Your MBoard may have BIOS protection and you really aren't flashing the BIOS. When you cleared the CMOS using the jumper did you have the computer unplugged? Did you immediately enter the BIOS and reset values. I am not sure what you have right now.

I flashed BIOS because I couldn't do anything with computer, which gives monitor no signal. so I thought maybe it is bios, thats got damaged somehow. Anyway, this didn't helped.

My motherboard is intel dp35dp and I'm flashing it from burned cd (with bios file "DP0326P.BIO" downloaded from intel.com).

When I cleared the CMOS did unpluged/shutdown computer.

And I can't enter BIOS setup, because my monitor shows no input signal (except for when I put that recovery cd and it starts flashing, then monitor shows me flashing process with confirmation, that everything went well).

Obviously everything didn't go well. Are you positive you used the correct BIOS and flashing files? Even something as small as the same model MBoard except the version number can cause issues. Double check to verify you did use the correct files.

Does your MBoard have onboard video? Are you currently using it? If available try it as that would be the default graphics.

Yeah, I used correct bios. My mb doesn't have onboard video card so I can use only my gf8800gs :(

Have you tried clearing the CMOS again with the machine unplugged?

Intel boards are generally not designed with overclocking in mind, if that was your intention from the start, you NEVER should have gotten an Intel board.

Are you an experienced overclocker? How much did you crank up the FSB? The problem with overclocking software is that it usually doesn't allow adjustment to the PCI, AGP, PCI-e, RAM buses, so that has to be taken into account when raising the CPU FSB...otherwise these other buses will go too far out of whack & lock the system.

You didn't download a "recovery BIOS", you downloaded a BIOS update & the instructions say you do NOT have to remove the jumper.

"The ISO Image BIOS Update allows for the update of an Intel® Desktop Board BIOS....without the need to remove the BIOS configuration jumper."

It goes on later to say:

"In the unlikely event that a BIOS update is interrupted, it is possible the BIOS may be left in an unusable state. The recovery process requires the chassis to be opened to move the onboard BIOS Configuration Jumper."

Go back to square one...disconnect all your drives & remove all but one stick of RAM. Unplug the power cord & use the ClearCMOS jumper to reset the BIOS, then see if you can boot, get a display & access the BIOS. If you can, immediately correct all the settings, save & exit. Reconnect your drives, boot into safe mode & uninstall the overclocking software.

You have a quad-core CPU & 4GB RAM...how much more speed do you want? If you're unhappy with your system's performance, buy a decent motherboard.

yeah, I've tried to unplug everything and use only one stick of ram. didn't worked. Anyway, on monday I'm taking my pc to computer service. If it's mb then I'll just buy gigabyte or asus.

As far as I know (read it on other forum), DP35DP "remembers" FSB frequency you set with SetFSB. So when you overclock too much it tries to start with that frequency but it can't and BIOS doesn't have appropriate code to return to default settings automatically if overclocking fails.

You needed just to reset BIOS manually with jumper on MB. No need to flash it, you could flash it with wrong update or something, flash it again with latest BIOS version and reset it with jumper after that just in a case. You can flash even without monitor signal.

SetFSB and Intel DP35DP are just fine for overclocking if you like to overclock without changing of voltages and don't care about overclocking with open case to find that sweet max FSB frequency your CPU will work stable with (to have an ability to reset BIOS with jumper when you overclock too much).

Well I have the same board, and I as well, could not get an monitor signal after playing with fsb. I couldnt get the cmos to clear even by taking out internal battery for multiple hours. But then I did it the old fashioned way and RTFM.
To clear the bios you need to move cmos jumper (near internal battery) to pin 2 and 3 then turn the pc on. This is the config mode for this board.
I tried everything, because normally pulling the battery or switching to the opposite pins for 10 seconds works. Not for this crafty board.

You also need to remove all power from the board while clearing the CMOS.

My entire life, i always have an Intel Desktop Board. So let me give you an advise.
When you soft-overclock your board (whit clockgen, setfsb, systool etc) and the overclock fail, the only thing that you have to do is unplugged the power cord of the pc, whait 5 or 10 seconds and the reconnect it. that should work fine in all the cases.
Reflash your bios may be a bad sollution since the overclocking software changes the values on the clock generator, not in the bios or the operating system.

thxxx and good speed
