yep sounds like poor thermal displacement on the old (well new) CPU

*

Possible shorted modem from a lightning strike causing the system not to boot up. Or just a dead modem in general.

*

on the n1015v it was by the modem, which was behind one of the back panels on the bottom of the case.

*

Is your HDD detected in the BIOS?

*

I would be tempted to try a new cable first fella

*

Try clearing the BIOS, remove the CMOS battery for a few minutes and then replace the battery and try again.

Also it could well be a thermal problem. I had a Compaq EVO N1015v brougt in to me for...

Voltage checks are important too, checking the various voltages help isolate problems. Also checking the various power regs on a board to see if they are ok can help you.

Resistance checks on...

Plus you have to weigh up the cost of a new board versus the cost of repair. Boards cost from as little as £20 nowadays for a basic board, it's that sort of cost that drives companies to repair or...

Is there a way to check it on an ext monitor?


*

does it shut down under heavy load???

or at anytime?

*

yep if its constantly on then it will be like pressing and holding the power button to knock the PC off.

The old screwdriver power on technique will verify if you have a serious problem or not.
...

so the fan connector is broken? if its not sitting in the connector properly? this might be the reason why the fan is working intermittantly because of a poor connection.
And if the fan is working...

Does seem like a dead psu

no chance of swapping it with somebodyy elses psu to check ;)

*

LEDs for fishing, new idea that ;)

anyway all joking aside my point I make regularly is that it came from the earth and so its only going back where it came from :D

*

you hooked what up to the old PC, the monitor??

*

So you overclocked your processor?

So may have pushed it over its limits

*

no not at all. Most inverters cost around £25-£40 pounds, I know some american sites that sell them for around $80 for various models.
However you may replace the inverter and still have no...

It's doubtful that it is the power supply as he said it does it with or without the power supply in, i.e running off batteries.

Yep it could well be heat stress to the board, if the fans/fins are...

the jumpers he refers to would be where you connect the leads from the power button and front panel of the case into the MOBO. If these are wrong you dont get much life out of the system.

*

Maybe a loose connection in the case.
If you feel confident open it up and check all cabling to make sure everything is connected as it should be ;)
*

yep check all things thermal first (fans, vents etc) clean out all dust from the system, I find a little WD40 sprayed into the bearings of the fans helps give it a new lease of life.
Once it is all...

bloody hell, water and electrics never mix so they dont, lol

*

It's illegal to use tin/lead on LEAD FREE boards, but you can still use tin/lead on tin/lead boards. And really if you have a nasty joint problem, a mixture of tin/lead like kegger's says up there is...

borrow a graphics card that you know is a good working one and "try before you buy" Then you will know for sure then.

Yep bigger case and better cooling support is always a good choice

*

its a difficult one to read

sounds like they re-applied thermal paste I suppose on the cpu?

Make sure the heatsink is sitting FLUSH to the cpu, ensuring that the cpu doesnt over heat and cause...

Cleaning off the CPU and re-applying some DECENT thermal paste could help the issue aswell.

*

Chinese designs are a PAIN!!!!!!!1 cheap build quality and poor solder joints being made. And now with lead free coming in the poor solder quality is really affecting mainboard connections. BGA's are...

is it a desktop or a notebook???

if it's a desktop could be an underpowed PSU, get a bigger wattage put in it and see if it gives more stab ability :D

*

There is no "Golden Fix" when repairing at PCB level. Yes on certain products there are "Stock Faults" but only on certain systems and products.

By just saying "Oh I was told these broke the most,...

Sounds like heat damage.

Extreme temperatures cause the solder joins to become brittle and break. So the temperature range causes expansion and contraction of the joints, causing stress and then...

Sounds like a faulty power rail.

Ebay could be your saviour trying to find your MB for the laptop. Gotta be the same type due to the port outs in the plastics etc.

*

what a pain, sounds like the charging/power circuit is faulty with would mean changing the power reqs and other SMT parts (a pain to find and match up)

*

happy to help dude;)


*

Sounds like a bad solder joint somewhere (probable one of the BGA's)

If it runs fine once warm and not when cold then this does strike as a dry joint somewhere on the board. This will either mean...

possible faulty touchpad controller.

*

That strikes as your inverter is dead dude if you can see faint images but have no backlight.

*

Could well be due to a fault on the charging circuit. Tell me, does it come with a seperate Charger Board? These are notorious for causing charging and power faults.

If it does have a charger...
