After I switched the power off from the back of PC to force shutdown the PC due to it freeze, the PC could not bootup again. When I powered it on, the fans runnng, all of the lits on, the CD lit on, the CPU heats up, and Hard Drive spinning, but No beep, no bios, and its blank screen. I played with RAMs randomly in different slots, replaced the video card on AGB slot. The Motherboard just don't react whatever I do. One thing, the small fan on the top of heatsink was not functional nomally, it spins very slow. Anyone has idea what could be the problem? Your input would be appreciated.

This thread shows a classic “powers on but no POST” symptom: lights, fans and HDD spin, yet no BIOS screen or speaker beeps. Several members already suggested CMOS/clearing and component reseats; ’s post (missing CPU) and ’s bent-pin report are useful reminders that the cause can be anything from a missing/incorrectly seated CPU to a failed board. The following checklist prioritizes low-effort, high-value checks and what each result typically implies.

Recommended checks (in order):

  • Confirm a POST speaker is actually present on the motherboard speaker pins. “No beep” is only meaningful when a speaker is connected.
  • Ensure a CPU is installed and the socket/pins are intact (see ’s bent-pin case). Verify the CPU cooler is mounted and the fan is on the CPU_FAN header.
  • Verify main power: both the 24-pin ATX and the 4/8-pin CPU power connectors are fully seated. Check any GPU power leads if a discrete card is used.
  • Perform a bench/minimal-boot outside the case: only motherboard + CPU + cooler + one known-good RAM stick (use the slot the manual recommends) + PSU + speaker (+GPU if no integrated video). Swap in a known-good PSU or RAM if available.
  • Inspect the board for physical damage (burn marks, bulging caps) and the slow heatsink fan noted by ; a dying fan can be a symptom but not always the root cause.

Interpreting results and next steps:

  • Beeps or POST codes narrow the faulty component (consult the board manual for code meanings).
  • If the system still shows nothing with a known-good PSU/CPU/RAM and a speaker attached, the motherboard is the most likely failure. A slow chipset or heatsink fan raises suspicion of prior overheating; replacement of the board is reasonable if bench testing rules out PSU/CPU/RAM.

Safety/caution: avoid shorting pins, observe anti-static precautions, and consult the board manual for diagnostic LED/beep code meanings. If bench tests are inconclusive, professional diagnostics or replacing the motherboard is the practical next step.

Try unplug the power cord to the PC then pressing the power button over 20 seconds do not let go for over 20 seconds.
This willl discharge the PC and reset the system as well.

If the small fan is on top of the mobo chipset, maybe the chipset is fried.

Hope this helps!

Thanks in advance Bill:).I surely will try this :$, Im hoping things will go just fine. If not, Im planning on buying a NEW motherboard:-/ > Is this a GOOD IDEA ?

try reseat CPU, HDD data cable and use 1 working RAM, COEJO.

Hope this can save you some money!

if th Fan is working sluggishly then you have to repalce it. PS try another processor perhaps your's is fried as PcTestCard.com suggested...
