1485216 2022-03-30 04:11:00 This old PC fails to start up INTERMITTENTLY with 1 long beep and 3 short beeps.

Pressing the power button and restart it usually gets it to start up properly. It works perfectly OK when it's started

Win10's inbuilt Memory test found no errors.

I am now running Mem86 v4.3.7 from CD to test the memory. How many hours should I run the test?

Any other suggestions? I have removed both the RAM sticks, cleaned and re-seated.

Update: Asus MB Z87-C

1485217 2022-03-30 05:26:00 A google search suggests a GPU error, do you have an add in graphics card ? If so check any power connections and maybe reseat it, check for build up in the heatsink etc.

I've also found changing the CMOS battery can be worth a try on older systems for all kinds of weird behaviour.

May need to buy a CMOS battery to try out.

1 long beep followed by 3 short beeps is a graphics-related error. If you get the same beep code, this could be a possible bad motherboard or processor.

Thats a 2013,14 vintage, 8 years old.
Probably the motherboard dying, given its age .
