OK, I had to pull the mobo and CPU out a while ago as it was terribly unstable, so I need a little advice, or more, confirming my suspicions.<br><br>
It is an Asrock mobo (the one with the 'safe' clocking facility) and a P4 2.8GHz proc (800MHz FSB).<br><br>
The problem was the CPU was always running very VERY hot, but the mobo had ramped up the VCore on the processor and I could find no way of turning it down. The machine would give BSOD very regular.<br><br>
Now, I am thinking that the MOBO had gone faulty, and the CPU might still be ok, what are your thoughts.<br><br>
I hadn't overclocked the machine either.

Well ASROCK motherboards are horrible for overclocking Period really in my experience. The safe overclocking feature isnt all that great as you cant set the increments of your V-core thus it will automatically raise it according to the higher FSB which can cause issues such as the ones you are having. Now increased V-CORE can damage a CPU however im willing to be its ok. I would drop any overclock you have for safety sake and see how you go. I f you still get issues test your CPU in another motherboard if possible.

Thing is, I never overclocked it in the first place, it just started to become 'unstable' so I investigated all parameters. Guess I will have to chuck a new mobo at it, and hope, be cheaper than chucking a new P4 at it.

Well sudden instability can point towards bad RAM and or bad CPU. I would run memtest on your RAM to make sure its ok. Also update your motherboards BIOS to the latest version.<br><br>

Yeah, I did all that, I flashed the bios, that didn't work, I tried different RAM, which didn't work (but works in my current SMD setup). I am not sure how sudden it was, but I just started getting little errors, and you know what Windows is like, it just compounds itself.<br />
<br />
I think I have convinced myself the ASrock mobo is at fault, as it just decided to ramp up the core Voltage to (if I remember) 1.54v which would account probably for the rather toasty CPE.<br />
<br />
So, where can I get a cheap LG775 socket 800FSB mobo from??

Are you sure your heat sink is on correctly?

I take it you are running DDR2 memory with a 2.8GHz Prescott CPU.<br />
<br />
If you download this <a href="http://www.cpuid.com/cpuz.php" target="_blank">app</a> and post a screenshot of the CPU/memory tab it will confirm what you have.<br />
<br />
If this is the case you could get something like this: <a href="http://www.tekheads.co.uk/s/product?product=606302" target="_blank">Asus P5LD2 SE i945P PCI-E</a> for only £68 and it supports Core2Duo for later upgrades.<br />
<br />
Not sure about overclocking on this board though.

no, DDR400, as it is 18 months old and only supports DDR400, system is dismantled, I tried re-seating the CPU on new AS5, to no joy, I ended up rebuilding the system on an AMD CPU as wasn't to happy with the P4 performance, the AMD just feels faster, and with the system crashing, I was at risk of losing too much data.<br />
<br />
So, the more I discuss it, the more I do think it was the mobo, as even on trying to install XP, it would BSOD.<br />
<br />
Oh, and I just want as cheap as poss mobo, as this is now being demoted to my workroom, to replace an Athlon 950, so cheap as chips.
