After overclocking, the system crashes during BSOD and stops responding afterward.
I own an Intel Desktop Board model DP55WB with an i5-750 processor.
I chose to increase the clock speed.
Initially, I managed to reach +100MHz and ran IntelBurnTest at full capacity repeatedly.
It turned out my maximum overclock would fall between 3.6 and 3.7 GHz, but it ended up causing a BSOD at 3.7GHz.
After restarting and adjusting the bclk accordingly, I can no longer launch Windows.
I’ve checked that all drives and flash drives are recognized properly.
The system boots normally.
I can still edit BIOS settings.
However, it won’t boot back into Windows, even with the default load optimized configuration.
One observation is that when I set the CPU voltage to +50 or +100, I can view the performance tab in main mode, which lists default, current, and suggested values, but it displays 0.0000V for the CPU voltage.
I really need a motherboard repair expert!
I might attempt a complete CMOS reset by taking the battery away for some time. It's possible the OS was damaged by excessive input. A fix using the installation media could restore functionality if necessary.
I've attempted to boot recovery media and even tried a memtest 86+ disc, but nothing is working. The CMOS power drain clear didn't resolve the issue, as the date reset to 2009. Should I consider leaving the CMOS battery out longer?
I plan to reinstall the CMOS battery and attempt to start it when I return home. I'll share the outcome once I'm done. I really hope it works again. I don't want to end up needing a new board just because the motherboard tries to run the CPU at 0v past the BIOS for some reason.
EDIT: I'm not sure if this is the issue, but based on the voltage settings in the BIOS, that seems like the most likely cause.
Keep me updated. The 0v is incorrect; it's unlikely your system would operate. It seems the boot sequence might be off now.
If the boot sequence was incorrect, it would start when I pressed F10 and chose the hard drive, yet that also didn't function properly. In reality, I don't even see the command line cursor in the top-left corner during that process.
Update on the startup: No Dice. I received numerous CMOS-related error messages, but the system remains inactive beyond the POST stage. I attempted manual selection to boot from the hard drive. I also tried booting from USB recovery media and a memtest86+ disc. A Ubuntu LiveDVD was used, yet nothing resolved the issue.
Another update: I attempted to switch to UEFI mode and used a UEFI-compatible recovery/installation flash drive, but it didn’t work. I also tried connecting the power supply jumper at 230V instead of 115V, which caused the fans to overheat and stopped functioning afterward. Once I switched back to 115V, nothing changed.
I also tried re-flashing the BIOS, but after selecting the file to flash, the system would reboot into flash mode and then freeze during POST, returning to the same black screen as when I pressed F10 to select a drive. Forcing a reboot afterward didn’t alter the outcome.
My confusion is growing—drives appear normal in BIOS, bootable devices show up correctly, and the hard drive is listed first. However, overvoltage checks indicate 0v instead of dynamic on the CPU. I’ve tested all VRMs and found no signs of damage, and I’m certain the 4-pin power connector is intact, though it only briefly activates the fans before shutting off.
I’ve swapped RAM sticks and ensured both are present, but nothing changes. It seems the system is unresponsive after POST.
Very unusual scenario. I'm puzzled why the 230v didn't trigger the PSU as expected. I recently moved some cables around at a work PC a few weeks ago and that's when it happened. Considering you can POST, it seems the CPU, RAM, and PSU appear to be functioning properly. It looks like the BIOS might be corrupted or there could be a hardware issue with your setup so far.
