I got started on the computer today. Here are the parts
Asus P5B-E
C2D- Conroe 6400
Lite-on DVD RW
Lite-on DVD Rom
Mitsumi floppy/card reader
G.Skill DDR2 800
XFX 7600
visiontek tv tuner
2-320 gb seagate hard drive
Running MCE 2005
I got it all set up and everything seemed to be going fine. I have been installing the drivers and windows updates and all of that was done. I was now working on getting some software installed and had installed the logitech setpoint for the keyboard and mouse. I installed the antivirus avg, windows defender which I had to uninstall because it kept on going corrupt. Anyway I was messing with the Al Lifestyles features and was just learning and playing around a little bit with fan settings etc. Nothing major at all. It had to restart and bam. It won't restart. The fans and dvd roms work, and the power light on the mobod is lit. No power to the screen at all now. What is up. I cleared the cmos and it said it couldn't find the dvd rom, floppy etc. but it won't let me get into the bios. Does anyone have any idea at all. I have built many computers and had minor problems but never this. WoW.

Good followup from and well done troubleshooting by . The problem described — a live system with fans and drives but no POST/video after fiddling with the motherboard control software — is a classic case where an OS-level utility or an automatic "tune/overclock" feature pushed settings outside a stable range. Below are a concise, practical checklist and a few safety notes to use immediately if this happens again.

  • Confirm basics first: test the monitor and cable on a known-good machine and try a different video cable/port. That rules out display issues before more invasive steps.
  • Use POST diagnostics: listen for beep codes or check the board LEDs/Q-codes if present. They point to CPU, memory, or GPU faults.
  • Minimal boot (bench test): power the board with only CPU, one known-good RAM stick (try different slots), and GPU (if needed). Remove all drives, PCI cards, and USB devices. This isolates components that stop POST.
  • CMOS reset and safe defaults: power down, unplug, discharge (press power button), then use the motherboard jumper or remove the battery for ~30 seconds. Boot and load BIOS optimized/default settings. If the board came up after the reset for , that fits the pattern.
  • If Windows won’t boot or the utility blocks startup: boot Safe Mode (F8 on older Windows), uninstall the vendor utility, or use System Restore. If the utility wrote persistent firmware changes, consider reflashing to a stable BIOS only after you confirm the board is otherwise healthy.
  • Preventive practice: avoid automatic one-click overclock tools until the system cooling, PSU headroom, and voltages are confirmed. Make changes incrementally, monitor temps/voltages, and update BIOS and utilities only to stable vendor-recommended releases.

If the board still refuses POST after these steps, do a bench swap (different PSU, RAM, GPU) or contact the motherboard vendor. The goal is to separate software-induced configuration from an actual hardware failure.

You have conflicting information here, first you say that there is no power to the screen which I take to mean that there is no image at all on the monitor. With no signal from the computer the monitor should still turn on and have some message or color bar to indicate that it's ok.

Then you say that it won't let you get into the BIOS, how can you tell if your monitor has no power/signal?

It is probably poorly stated on my part. What I should have said was the screen was black with no info. The computer was running and there was no little box telling me this. I fixed the problem anyway after many tries I got it to boot and found it to be some of the software with the mobod that actually was overclocking the board. No problems since I uninstalled it and have had it running for 2 days and no problems.
