Right ok my friend told me his computer 'Wasnt Working' so i just assumed there was a virus or needed a reinstall so i offered to help.

I get his computer to my house and when i pluged it in it just turned on automatically for 5 seconds then turned off then repeated the process over and over. At first i thought it might be the power switch being faulty so i unplugged that and it did the same thing.

So i changed PSU thinking that it might be a dodgy connection, but that didnt work.

So i asked you guys on here and was told to put a new mobo in it, so i did that ordred the below.

http://www.overclockers.co.uk/showproduct.php?prodid=MB-114-MS&groupid=701&catid=5&subcat=326

Got it home and rigged it all up and plugged the power back in, good news the computer didnt turn on, on its own anymore. So i pressed the power button and it whirred up but wouldnt display anything on screen just a no signal message on my monitor so i did the following:

  • Removed graphics card and ran with onboard graphics
  • Tried all 3 bits of ram in each of the two slots
  • Unplugged HDD
  • Unplugged all USB connectors etc
  • Removed all PCI cards
  • Cleared Cmos

But couldnt get a screen to apear it is driving me mental but i know it is fixable! Could it be the analog cable i am using? or the ananlog port on my Monitor?

Thanks guys apreciate any help.

It could well be the analog port or cable, can you not use DVI or anything else?

Since it's all powering up to some degree it should be working - just to check, did you return the CMOS clear jumper back to "normal"? I know it sounds daft, but it can give all the symptoms of turning on, but no output to the screen. I spent twenty minutes assuming my first build was duff before realising that I just hadn't replaced that little blue jumper.
 
Pentium 4 of some sort
1.5GB DDR2 533mhz (2 x 512mb & 1 x 1gb)
PCI Express Graphics (ASUS not sure pretty sure it is ATI)
SATA HDD
IDE Optical

Yer the jumper is put back on and i have tried it off/on yer it could be the cable but i dont think ive got one of those DVI to Analogue adaptors.

But i will try and find one and see if that works.
 
Not that it probably matters, but would 2x0.5 and 1x1gb be 2gb total?

Have you tried running individual sticks of ram, to be sure they aren't the problem? It's possible, although unlikely, that the motherboard's memory controller went and damaged some or all of the ram.
 
If it is Pentium 4, then you have the Wrong motherboard, or is it a wrong link?

And for the ram (2 * 512 mb = 1 GB) + (1 * 1 GB) = 2 GB

I’m confused
 
Well the mobo you ordered (that you linked to anyway) is for an AMD socket, secondly did you check to see if the mobo you bought supports P4? Even though the motherboards say LGA775, the vast majority don't support P4s.
 
Are you sure it's fine, since not all socket 775 boards support P4s, what's the mobo you bought; several people have been caught out by this.
 
Right have finnally scraped off the thermal paste and the CPU reads to be this one.

Which if i think i am correct is incompatible according to the above link from happy.

Am i right?

Before i commit to buying the guy a new CPU am i definitely correct in saying that getting a new one/used one will cure the 'no visual' problem i am having at the moment?
 
You need to check as many components as you can before buy any replacement hardware.

Try parts from your machine in his to isolate the problem. Then you will know for sure. Once you know whats causing the problems order a replacement.

PS he did back up his files right? cos you will need to reintall the OS with a new mobo.
