Retro PC Finds 20th October at the Flea Market / Car Boot Sale 

Heya, you know by now love these carboot video's. a fast I5 is still a good machine.

In my experience the F10 key is the key you need to hammer on these HP OEM boxes to enter the bios.

Those intel boards mosfets do run that hot even with a working board - ive got 3 of them and put heatsinks on them because they run so hot they discolor the board over time - but yeah ive got one which does the same as urs but stops at d3 and ive found a super hot northbridge once i removed the heatsink - so i think its a faulty NB - ill wait for your bios flash as was thinking that was worth ago until i checked the NB temp

Richard, I don't know if anyone else mentioned this but with HP desktops you have to remove the power cable from the PS when you clear CMOS

You might have more luck searching for HP 290 G2 although most seem to have the i5 8500 rather than the 8400 in your example.

i5 for $20. Good deal!

At this point, the only change was ram slot and that resolved C7. I'd say, you have a faulty slot and a faulty ram, and you've been mixing them back and forth.

Thanks Richard, Im interested in this analyzer card you have, how do they work and is there a list of error codes available. Thanks

Your comments while looking at the HP reminds me of an old saying..... "Ya pays yer money ya takes yer chances"

hello richard, did you try to re seat the cpu? also check the cpu for its flatness, some intels get bend over tme inside the socket, due to uneven pressure at the sides. so the pins on the socket loose contact.

Change the wobbly cap. Seen it recently on another channel that the cap was broken inside, and that stopped the MB booting.

Not much in the way of details on the first even from HP Company: HP Inc.

8 4 zero zero you mean a 84 hundred then

8th gen I5 has gone down the drain since they are not supported by windows 11. I get 8th gen I5 laptops with ram, a screen, and storage for less than 50quid. Ok the desktop chips are better but they are cheap on ebay. Why do i buy old Intel laptops that wont run win 11? because they are no worse than many of the modern cpu's if you put Linux on them.
