My brother was watching a video clip on his 6/7 year old PC (running Win XP, the clip started buffering (I think that's the correct term) then everything went of, he tried to start the PC up again and got a series of rapid beeps about 8/10 then the black screen.
Its not the monitor ,as he connected that to a different PC and that was OK.
Any suggestions appreciated as the PC he has setup now takes about a week to change pages,really painfully slow as it was a cheapie with low spec and it is also old too.
I'm not sure about PC's but both of my old laptop "died" after approximately 3.5-4 years.
I managed to reinstall windows a few times on them when this problem occurred but got unlucky after a few times.
i would suspect the graphics card might need reseating ,if it has an external card .
as for a newer o/s, if its that old ,the specs might not be upto requirement
for win 7 ,but possibly vista would run.
Daxian is right, 8 beeps is very often a graphics card problem. If it is a desktop take off the side panel and see if you have a separate graphics card and if you do then do as daxian suggest and take it out, give the contacts on the card a good wipe over and push it back in again. If the graphics is part of the motherboard you may be snookered but you may also have a slot available for an expansion graphics card and you could put one in there.
I did not post back here as this is my brothers PC he was going to dispose of it, so I haven't done anything at all, but he informed me he had not got rid of it so I wondered if it was worth trying to reinstall windows as this should be within my capabilites
I don't know what the graphics card even looks like but I do know where memory is and what it looks like.
Unlikely that reinstalling windows will help as beeps are symptomns of a hardware problem such as memory / graphics card.
It might simply be cured by a removal and refit of both memory and graphics card as they can work loose overtime due to expansion and contraction as the machine meats up during use and cools off when shut down.
The graphics card is where your monitor cable plugs in at the back of the PC - undo cable remove side panel screws at rear and slide panel rerwards to remove - undo screw that holds graphics card down at rear of PC - disconnect any power leads that might be fitted to the card - wriggle the card slightly as you pull it up - refitting is just he opposite, making sure the card is firmly pressed into the slot.
