Sonvy Vaio PCV-C31L Refuses to boot

March 31, 2009 at 11:54:13
Specs: Win XP
Hello,
My relative has a Sony Vaio PCV-C31L,
and it will not power on.

I've tried my best to consult w/ him, but no luck.
Here is the information I've gotten so far:

When plugged into wall outlet, both Mobo and PSU light flash synchronously.
W/ no other hardware using the PSU except what's on the mobo.

Once all hardware is unplugged, the PSU has a continuous light, w/o flashing, (Blinked w/ mobo)

He has no other hardware installed then what it came w/.

Everything is correctly installed (or plugged in), still no luck.

PSU is a "Bestec ATX-300-12EB3"

Keep in mind I can only contact him through telephone.
So I'll have to explain it to him over the phone.

Thank you for any answers,
We appreciate what ever it may be.

More information will be provided if needed.

"Keep in mind I can only contact him through telephone.

Surely you can supply the link to this page to him and he can look at and/or copy the info on another computer.
Or he could go to www.computing.net,
scroll down to and click on Message find,
type 56319, change the category to General Hardware.

If he does copy it, the longer links on this site are shortened - the shortened links have 3 dots at the end - to save visual space and are a link to the actual link. He must click on the shortened link and copy the actual address, paste it into the saved text, and delete the useless shortened link in the saved text, or RIGHT click on the shortened link, choose Copy Shortcut, paste that into the saved text, and delete the useless shortened link in the saved text.

The following is about emachines computers, but it applies to ANY computer with a BESTEC power supply.
.....

emachines computers are well known to have el-cheapo power supplies that tend to fail more often than average, and when the power supply fails completely, they are a lot more likely than average to damage something else, often the mboard.

If you have not been fiddling inside the computer case just before this happened and have not changed the ram installed in it, it is very likely that if you replace the power supply BEFORE it fails completely, doing that will restore your system to working again.

Unplug the cord to the computer, or otherwise switch off the AC power to it, open up the computer case, and find the label on the power supply - if the brand is BESTEC I advise you, if you find ANY indication the power supply might be in the process of failing, DO NOT trying booting the computer anymore - if the PS fails completely there is a strong likelyhood it will trash your mboard!!!!

Failing power supplies are common and can cause your symptoms.
They often partially work, fans and hard drives spin, leds come on, yet you get no video and the mboard will not boot all the way.
Check your PS.

DO NOT replace the power supply with another BESTEC one!
In most cases you can replace it with a standard sized standard ATX power supply.
.......

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo PS.

........

General things to try, but it's a lot more likely the power supply is the problem.

Unplug the case/power supply.
Power off your monitor.
Open up the case by removing the left panel as seen when you're looking at the front of the case.
Check all the connections of the wiring to make sure they are all the way onto their pins and into their sockets, especially the main connector from the power supply. The wires close to the mboard going into the main connector/socket should be more or less perpendicular to the mboard surface rather than at an angle. Make sure all cards in slots are all the way down in their slots.


See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:
