Hey, I am facing this problem from yesterday and I was just using my pc like normally and I plyggin my wifi adapter and speakers but suddenly a BSOD came and it restarted my pc a few times, I tried the automatic repair but after that my pc won't boot and fans and lights working but dispaly not coming plus mouse and keyboard also not working.
When I reseat the ram after that the pc would boot, but afyer a shutdown it won't boot again.

--Things I did--

  1. Removed CMOS and placed back after 5 mins
  2. Check cpu pins all great

Given the BSOD happened right after you plugged in a USB WiFi adapter and speakers, and now the system only boots after you reseat RAM, this smells like two things at once: a marginal DIMM/slot contact plus a USB overcurrent state that only clears when the board fully discharges. Reseating RAM is forcing a full power drain and retraining memory, so it posts once, then fails again on the next cold start.

Try this focused sequence (building on and ’s strip-down advice), aimed at reproducing-then-isolating the failure:

  • Do a true cold start: switch PSU off, unplug power, hold the case power button 20 seconds, wait 1 minute. Now unplug every USB device, including the front-panel USB header from the motherboard. Boot with only CPU, 1 stick RAM, GPU if required, and display. If it now posts consistently, inspect USB ports/headers for bent pins or a damaged device.
  • Clean the memory contacts and slots: blow out the DIMM slots, then wipe the module’s gold fingers with 90%+ isopropyl on a lint-free cloth. Test 1 stick at a time in each slot. Note whether the failure follows a particular stick or slot.
  • In UEFI, disable XMP/DOCP and any Memory Context Restore/Fast Boot options, then run the RAM at JEDEC defaults. Marginal training can present exactly like this.
  • If the board supports CPU-less BIOS/UEFI Flashback, update to the latest stable release. Corrupt SPD/cache parameters or early AGESA/MCU bugs can cause one-and-done posts.
  • Breadboard outside the case to rule out a standoff or rear I/O short. Also disconnect nonessential headers (front audio, RGB, extra SATA) during testing.

If it only fails in one DIMM slot or only with USB headers connected, you have the culprit. If the behavior persists across known-good RAM and minimal USB, the fault is typically on the motherboard’s memory or USB power switching circuitry.

But at this age board, we try a few things then replace the board and whatever else is required if we have to change to a board that doesn't support the old CPU and RAM.

Also, we always pop in a new CMOS battery at such age because the battery is 25 CENTS in bulk. Troubleshooting low CMOS batteries is many dollars so we never do that. Put in new. Still, once in a while a tech will get upset at popping in a fresh 25 cent battery. Chalk it up to being a new tech?

So the BIOS setting has been changed, the new CMOS battery installed, CMOS values set to default except for fast boot and it fails. The usual is a failed motherboard.

No power is also a motherboard function. A Volt meter is used to check if the +5V StandBy is present and then we know the motherboard is the one to call for power on the green wire (see Green Wire PSU Test on google) but hey, if you feel it's the PSU, a little cheaper than most motherboards so why not get a good one?
At the shop the tech bench always has a spare to swap to test for this area. As a PC repair person you can't go far without good spares.

Hi,

The RAM might not be in the right slots, not likely with two RAM slots and two RAM sticks.
The DVD drive might be faulty if there is one. I take it you've disconnected everything not needed to boot, including USB drives.
Many components like the CMOS battery or power supply only last for 1.5 years. The power supply might not be powerful enough. Can you replace both?
The RAM speed might be too low, can you try RAM that's a higher speed?
