Paggee Posted August 14, 2006 Posted August 14, 2006 Hi all, I had some problems with BSOD so i cleared CMOS and now i cant boot. It gets to the point where it scans for IDE/SATA drives where it says "CMOS Checksum error" F1 to continue or Delete to enter bios. If i choose to continue the screen turns black (monitor does not power off, so vga adapter IS sending some signal to the monitor). If I want to go to the BIOS by pressing delete it hangs with a little bar in the top left corner, flashing. Doesn't get any further than that. I can't update the BIOS and clearing it again doesnt do anything. I tried removing ram, sata disks, IDE drives and starting up with the jumper set to Safe Boot. Nothing helps. Can you please help me? Or is this board defective? Quote Share this post Link to post Share on other sites More sharing options...
tasr Posted August 14, 2006 Posted August 14, 2006 Welcome to DFI-Street Do me and all the other people that will be helping you out a big favor. Put together a complete signature per the rules. Look at the examples. Thank you. Quote Share this post Link to post Share on other sites More sharing options...

lowboy Posted August 14, 2006 Posted August 14, 2006 More information would help. Is this new build or old was it prime stable .The PSU is under powered for your rig suggest getting one from the recommended list. Try the cmos clear from not boot as shown here and follow to the letter. http://www.dfi-street.com/forum/showpost.p...04&postcount=24 Quote Share this post Link to post Share on other sites More sharing options...
tasr Posted August 14, 2006 Posted August 14, 2006 As Lowboy pointed out, your rig’s PSU does not meet the minimal power requirements for a DFI nF4 motherboard. You need minimal of 480w@26amps on the 12v rail of good clear power for a single video card. This comes straight from DFI techs. DFI Recommended Power Supplies (UPDATED June 14th, 2006!) Minimum requirements is a 24-pin 480w power supply (PSU) Quote Share this post Link to post Share on other sites More sharing options...
Paggee Posted August 14, 2006 Posted August 14, 2006 It was prime stable, yes. And the PSU is fine, has been for 6 months. I cant perform that "clear cmos" because it suggests i put the ram in dimm2, but it wont even show post with it in dimm2. So that probably wont work.

Paggee Posted August 14, 2006 Posted August 14, 2006 I just tried different slots for my memory, and it seems the only way i can get it to show something on the screen, is when i run dual channel in slots 1 and 3. I cant start with only dimm 1 or the other dimms. Must be DC. Quote Share this post Link to post Share on other sites More sharing options...
tasr Posted August 14, 2006 Posted August 14, 2006 Leave the memory where was and clear the CMOS as Lowboy posted. Stability is the name of the game. To get the stability you need in a DFI rig you need good clean power. PSU can disrupt so many things in ones rig. The stability can go at 1st, which then gets worse and worse as time goes on. Then major power issues with the motherboard and it will seem stability related. Components can also fail or seem to cause stability issues. Basically the PSU is slowly dying and may take your motherboard and or components with it. A PSU failing can happen all of a sudden or slowly over time. Power requirement for DFI motherboards are very high because they where designed from the ground up to overclock. A good quality PSU with ALL the power connectors plugged in will make a world of difference in stability and overclocking. These are; 24-pin main power connector 4-pin 12v secondary connector or EPS 4-pin 5v/12v molex connection or HDD-type 4-pin 5v/12v floppy connection or FDD-type Quote Share this post Link to post Share on other sites More sharing options...

It just starts as it would if I did not hold insert. As far as i know, not only the wattage of the PSU is what matters, but mainly the amps. I know for a fact that a Seasonic 430W PSU is way better than a cheap 600W and should handle the job fine. These symptoms cannot be caused by my PSU. I dont really get it. My mobo doesnt react like it should when im following these guides, so it seems defective to me. Is there a checklist i should go through before sending it to RMA?

Praz Posted August 14, 2006 Posted August 14, 2006 Do the CMOS clear as lowboy suggested for at least 8 hours. Quote Share this post Link to post Share on other sites More sharing options...
Paggee Posted August 14, 2006 Posted August 14, 2006 Okay. I will let it stand without battery, unplugged power cable and the jumper set to clear. We will see tomorrow. Quote Share this post Link to post Share on other sites More sharing options...
