My PC has given up, Lost Internet connection, Phoned Virgin and after 30mins they told me " net adapter" is corrupt ....and we would have to unistall and reinstall . This ws late last night, this morning, before we could do it the PC crashed...... nothing on screen. and screen keeps turning off. need lots of help
open the box .... look at the cooling fan/heatsink
if its full of fluff ... you need to clean it
be careful ... you musn't move the sink ... or you'll have to reseat using thermal paste.
a soft brush (I use wife's blusher brush ... big long NATURAL bristles ... not too stiff)
you might need to give the power unit a suck too ... use the vac for this ... but short bursts ... and make sure switched off (unplugged) - press on/off button .... then clean
Thank for help........the PC is on but the monitor is completly blank. so turn monitor on still blank, message comes on "no imput signal " then another message comes on "power saving " then monitor turns itself off.. I am not able to type anything because screen is blank pc stays on
Right .... it's your graphics card
1 do you have integrated or seperate graphics?
2 (likely) options
1 .... garphics card
2 .....Power unit
(could also be the mobo)
either way ... not easily proved...without hands on and spares
(also about 10000 other things it could also be)
From what you say ... something was failing .... and could well have resulted in corrupted data/drivers/etc
now it has failed ...
if the PC comes on ... but no video out
guess 1 is that it's the graphics card ... but ......
it that could be caused by other things
unless you have good bits you can swap might be a good idea to take it to a local mender ... see what they say
