Hi,

if i start my monitor before i switch on my pc it says 'no video input' which is obviously right...


but just lately it still says it even though my pc is on..and i have to switch it on and off at the mains sometimes four times before it kicks into action..


it is as if my hard drive is playing up...you can tell by the noise it makes..when it is switched on but saying no video input there is no real noise of anything being read if that makes sense...but when it eventually kicksinto life after a few switch offs it has different noises and you can tell it's being read


also my mouse has started just to freeze for no reason..

i thought all of this was due to alot of dust inside my pc but i cleaned it out this morning and i am sstill having these problems...perhaps my hard drive has just had it????

Have you run any diagnostics on your computer? If you have the ability, i would suggest running thorough scans on your system(ie; Defrag, CHKDSK, virus scan, spyware scan)
to see if everything is checking out. If these scans come up clean then it would be time to start exploring alternative solutions.

Does the monitor sometimes stays off when the computer is starting (before the windows loading bar appears) ? If so you can forget viruses, malwares, chkdsk and defrag : it's an hardware issue and it's not related to the hard drive.

What are your complete system specs ? If this is some brand computer give us the brand and model, else check the posting system specs link in my sig. Don't forget the brand, model and wattage of the power supply (look on the sticker that's on the supply itself).

Did you clean the dust from the video card fan as well ?

Enter the BIOS at startup (press del or look for some "press xx to enter setup" message), locate the hardware monitor screen and report your temps, fan speeds and voltages.

Have you tried another monitor ?

Have you checked that the video card was inserted properly in its slot ?

Have you checked the cable between the monitor and the computer ?

hi guys,,,thankyou...

i have done defrag and CHKDSK didn't come up with any problems


if i try and go into BIOS at boot up it just keeps over and over again asking me for a floppy or a CDRom and the pc came with none when i bought it so i had to switch it off at power again to get it out of that loop..

i looked for another way to look at my fans overheating etc and found a programme called 'motherboard monitor' which i run but i have to say i dont understand it or know what it's doing or know what do with it..i can't see it running but it says it is???where is it??does it give me some sort of list or report??if so how do i access it???

i don't think i did clean the video card or its fan thoroughly so will have a go at doing that a bit later...

i havent' tried it with another monitor as i don't have another one...

if it was the monitor surely i would not be able to detect a difference in sound coming from pc between when it boots successfully and when it doesnt??i know within the first few seconds of switching pc on if it will come on or not just by the sound which just sort of dips down before it comes on..if it get no dipping down sound i know it will just carry on saying 'no video input'...

When i run Motherboard Monitor it comes up with this but it means nothing at all to me i am afraid..is it information????is it some sort of report on my system???

sometimes when i am at my pc the room is cold as i don't go in there that often..i have not noticed if it only happens when the room is cold or not????could this be a factor???

dai

what are you running
video card
cpu
m/board
ram
power supply
brand
wattage

check the listings in the bios for voltages and temperatures and post them

bangra

Hi Dai,

when i try to boot up in bios as said above it just keeps asking me for a floppy or cd which i haven't got and it just keeps on in that loop until i switch off the power...

is there another way to get these readings or another way to get into the BIOS???

dai

http://www.techsupportforum.com/cont...e/Tips/48.html

see if you can borrow a larger wattage power supply to try in it

download a 98 boot disk
boot from it to a dos prompt and run
scanreg /restore

http://www.bootdisk.com/bootdisk.htm

bangra

YIPPEEEEEE!!Thanks Dai i managed to get into BIOS...here is info


CPU TEMP = 78.5c 173F

MB TEMP = 33C 91F

CPU FAN SPEED = 1004 RPM

CPU Q FAN CONTROL = ENABLED

CPU FAN RATIO = 35%

CPU TARGET TEMP = 75C

CHASIS FAN SPEED = N/A

VCORE VOLTAGE = 1.296V

3.3V VOLTAGE = 3.200 V

5V VOLTAGE = 5.094 V

12V VOLTAGE = 11.672 V

Then there was a little blue box that came up saying

OPTIONS IGNORED 77.5C/171.5F

On someone's advice i have just changed a few settings in the BIOS.

these are....

fan ratio - now on Auto

cpu target temp - 60 degrees which is the lowest setting..


is this the right thing to do? are my temps in my bios info too hot?

justpassingby

CPU temp is too hot and 12V line is low. Follow dai's advice : give us your complete system specs and see if you can borrow a better PSU to test your computer with.

bangra

thankyou once again for all your help..i enjoy learning about this and really appreciate it....

just to let you know i cleaned the fan and the video card of dust today..there was a big thick wad about an inch round of dust behind the fan which i have now dislodged...could this be the reason for overheating??

anyway here is my system spec...i think!!

meant to say i keep coming across the phrase 'overclocked' when looking for help..what does this mean???might this be something that i need to look at???

re downloading boot disk..my system is XP home...do i still need the '98 version???

also on the link there are afew option to choose for 98 boot disc..which one do i need???

TEMP DROPPED DRASTICALLY

I JUST went into BIOS to check cpu temps again and since removing the wad of dust from the fan its dropped and now reads

Cpu = 57 degrees C


perhaps this has solved the problem??

but the 12v voltage is the same....

dai

redo the paste it should be half that tempreture
no i was looking at the side win98 you don't need the bootdisk
check if the cpu fan has increased it's speed what you listed is to slow

http://www.newegg.com/Product/Produc...0corsair%20psu

bangra

thankd Dai..yes fan speed now increased..see below...problems do seem to have stopped but then again it was quite random and inconsistent before so it may just be going through a good spell!!!still it's teaching me and it's interesting...


CPU TEMP = 78.5c 173F **new temp 57 degrees

MB TEMP = 33C 91F

CPU FAN SPEED = 1004 RPM * new speed 1048-1054

CPU Q FAN CONTROL = ENABLED

CPU FAN RATIO = 35%

CPU TARGET TEMP = 75C

CHASIS FAN SPEED = N/A

VCORE VOLTAGE = 1.296V

3.3V VOLTAGE = 3.200 V

5V VOLTAGE = 5.094 V

12V VOLTAGE = 11.672 V

Then there was a little blue box that came up saying

OPTIONS IGNORED 77.5C/171.5F

dai

next time you cold boot turn the power off at the back then on again and see if it boots straight up
the cpu fan usually runs around 2500

bangra

oh my fan speed is still really low then??

if i switch power off then on again i then have to switch on the pc at its on/off switch before it boots up....it doesn't just come on..if it freezes i can' t turn it of at its on/off switch i have to switch off at the wall...

dai

leave the power off for a minute it resets the psu
if it boots straight up it indicates it is faulty

bangra

MY PSU is FSP Group and is 250 watt...

i don't really want to buy a new one unless this one really is causing problems...

could 250 watt be too low?

sorry Dai only just saw your last post..i did the cold boot as you said and no it did not boot up straight away i had to press the start button on the pc as usual...

dai

you would have to press the start button,did it boot straight up with no problem

bangra

oh! yes it did but to be honest it has at some point today not started straight away and that was since i took out the big ball of dust and fluff from the fan..i have started it alot of times and it did only do it once but that still must signify a problem...basically it's what the thread started wtih...i press the on off button on the pc and nothing happens and it just reads no video input on the monitor, if i press it again nothing happens so i have to switch off at the mains then do it again and then it's ok...could it by my psu that needs repacing??

dai

it sounds like it
see if you can borrow a higher wattage one to try in it

Hi,

I posted a thread earlier called 'no video imput' but has been closed...it was decided a new PSU might solve the problem..it has made it better but the problem is stilll happening..


i go to switch on my pc and my monitor says 'no video imput'. i have to keep my finger on the on button to start my pc up but often even then it makes all the right sounds and then just shuts off...

my cables are all connected properly...i don't kn0w what else to do...
