Alright, so this is roughly the problem (and pardon me for not being very clear, since my monitor won't turn on, I can't remember exactly what it said):

The computer is supposedly not very old (but who can you believe, right?), it's a Pentium IV processor with a newer monitor. It actually belongs to my grandfather and I don't work on it. Lately it started spontaneously freezing up and the restart button and/or ctl+alt+del didn't work. We had to press on the powerbar button that it's connected to to restart it.

Then, today, it started up normally but then started running in circles. It starts up, checks memory, then restarts again. The message that it displayed was something like 'CPU is not readable (or configured??), please check CPU Soft Menu' (which is in setup).

So, I checked the CPU Soft menu and since I have no idea what it all means, I tried changing the settings but as soon as I pressed 'Save&Exit', it restarted again and when I went back to the menu, it had the old values for the CPU. Then, out of the blue, it stopped turning on the monitor. The processor would make a normal sound but the monitor wouldn't light up (though it's plugged in and it's working).

At this point, I guess the only way to do it is do something physical with the processor, right? But what? I'm not going to mess with it myself. I'm computer literate but I'm not a technician. I only cleaned the fan and inside of the processor very gently but it didn't do anything.

Any advice?

Brief expert note tied to the thread: the combination of a POST loop, a BIOS message about the CPU, BIOS changes that do not persist, and sudden loss of video point to a hardware-level fault — but not necessarily the processor alone. The suggestions from and about component compatibility and bench-testing are relevant; a few ordered checks will narrow the failure domain without immediate parts replacement.

  • Verify the display path first: confirm the monitor and cable are known-good (try the monitor on another PC and try a different VGA/monitor on this PC).
  • Capture POST information: attach a system speaker (if present) and record beep patterns; consult the motherboard manual for the BIOS beep code meaning.
  • Clear and test CMOS: power down, unplug mains, remove the coin cell for several minutes or use the CMOS clear jumper, then replace the battery (CR2032) if BIOS settings fail to save. A dead RTC battery commonly explains settings not persisting.
  • Minimal-boot isolation: remove drives and non-essential PCI cards, leave only CPU, heatsink/fan, one RAM stick (try alternate slots/sticks), and onboard video if available. Boot behavior after minimization isolates faulty subsystems.
  • Inspect for visible board faults: bulging or leaking capacitors, scorch marks, loose heatsink or non-spinning fans. Mid-2000s boards frequently fail from capacitors or a flaky PSU; intermittent restarts and configuration loss often trace to the power supply.
  • BIOS/compatibility note: a BIOS that cannot identify a CPU can produce “CPU not readable” style errors. Updating BIOS may be required but only after confirming a stable boot environment and exact board/CPU model compatibility; flashing a BIOS on an unstable system is risky.

Handle internal checks with mains unplugged and ESD precautions. If bench-testing spare PSUs, memory or CPUs is not practical, a local repair shop can run the same isolation tests quickly — bring the motherboard model, the exact BIOS message, and any observed beep codes to assist diagnosis.

it sounds as though you might have a cpu thats gone faulty. if this is the case you will need to get a new one and possibly a new motherboard too;)

Ah, I was afraid it was the CPU after all. Oh well, thanks for confirming. I guess I'll.. seek help now. :-|

thats ok. come back if you have any more difficulty
:D

See if you can borrow a cpu for testing before you spend the cash. If you still get the error, then you know it just might be only the motherboard.

I've also seen ppl install cpu's rotated the wrong way. And yes, the pins only line up one way, which made it all the more amusing and unbelievable.

thats a pretty good spot of advice there but please, before borrowing a cpu for testing ensure that your motherboard is compatible with it.:cool:

Well, it should be installed the right way cause it did work for about half a year but the processor itself I think is pretty old and since we got it from a secondary source, I don't even know if it can be trusted. You can put anything in a pretty box but the insides might be ancient, you know?

So thanks again for all the advice!

know exactly what u mean.. out of curiosity how old is the processor. I.E is it one of the first P4 processors that shipped with PCs about 4/5 years ago when Win xp was first released.

secondly dont trust secondhand goods;)

Oh, I wouldn't know how old it is, again, cause it's secondhand. And yeah I myself wouldn't trust that but since it was for my grandpa and it's the 3rd computer in the house, naturally money needed to be saved and nobody really cared that much (my grandpa isn't exactly the computer wiz ;) ). It's too bad though cause now we'll spend more money than we would if we'd just gotten a crappy Dell or something heh heh

dont go for a dell... if you're looking for a cheap end machine look for a packard bell or a fujitsu siemens
