Having problems with your PC Desktops ?

PC Power Problem

\015 My Advent T9103 has for some time been experiencing problems on Start-up after being shut down the previous night. It would sometimes take a long time to Start-up when pressed momentarily and sometimes I would have to depress the Start button for a long time before it would start. As a result of this we decided to leave the PC on permanently. Unfortunately, the PC shut itself down the other day and we have not been able to start it up again since. Have you any advice please?\015

a64116f.jpg08c1cf0.jpgef4690e.jpgI also have a Dell 8400 heat problem . I know the problem ! I own a $1000.00 plus Raytek laser temp gun . I had some problems and started to read about all of the Dell 8400/4400 over heating problems . I out my new heat gun and started to test the temps. on the inside of my Dell 8400 ! Socket 775,Mobo Dell 0J3492,800 Bus,Bios A09.
\015\012The non-fan Radeon x300 card was 105-115.3 F after one hour !
\015\012The heat sinks over the chipset was the big problem . 107.8-124.6f after just one hour! The P4 cpu was 93-104f .
\015\012I am very lucky to have the laser temp gun I have .
\015\012The fix . I have all kinds of old fans and hard drive coolers from computers I have trashed over the years . I got new 40mm/10mm fans on the way from the bay . I had to use some old worn out fans 40mm fans to hold me over .I ordered a new video card also . THEY WORKED ! My temps dropped down to 82-85f on the chip set and video card after running the fans
\015\012I hope this helps .36b34e9.jpg
This is almost always a failed power supply unit, probably some burnt out capacitors, that would cause a shortage of current, not giving the motherboard enough energy to propagate the CPU, so the signal to boot never comes. Depending on your level of expertise on soldering and electrical equipment, you can replace a burnt out capacitor without trashing the PSU. Beware though, as you can run a risk of electrocution if not careful in doing so.

Option 2 is replacing the power supply, and judging by the size of its case, it will either be a Micro-ATX or a proprietary form factor, take in your old unit to a computer store so they can find a unit with matching pins and wattage.
