The Sony site for your model, and there is a BIOS update that fixes an issue with PCI Express video cards, here's the link http://esupport.sony.com/US/perl/swu...d=1714&os_id=7 You didn't mention if your problem starts right when the PC is powered on and you don't get the Sony logo, or if the PC starts loading Windows normally, but then when Windows is about to load up, you get the 'signal timing' message. If it's the latter, then try booting in Safe Mode and uninstall the BFG video card from the Device Manager and reboot. Then install the Windows XP nVidia driver from this link. Reboot and you should be OK *fingers crossed*

Hello,

I guess there is a conflict hardware both your video card. is the mboard has a built in video card? and added new add on card? if this so, then you have to remove first your add on card and use back the built in. then after you successfully boot using the built in then you have the chance to configure the add on card in the bios setup.

Beeps one long and a short installing pci express video card in a Gateway Gt5654


Don't automatically blame the video card. That boot code means memory refresh error. Try reseting your mems. If that fails pull out memory cards one at a time. If one gives the error and the other doesn't, you have your problem. Next, try to reseat the video card more firmly. Last resort, disable to on board video to avoid conflicts. Still think memory u is your best bet.

I have A dell gx270 desktop computer . i was searching on internet . Suddenly system hangs . When i restart computer it hangs on dell logo . i tried many time but it hangs on dell logo . i changed ram ,...


Firstly, make sure you installed the video card (if it has one) back into the same slot it was removed from.
If you are using on-board video, check the CPU is firmly seated into it's socket, you may have to remove the CPU fan to check this.
Next, check your RAM sticks again. Most (about 98%) of boot up issues arise from incorrectly seated ram sticks or ram sticks that have developed connection issues.
When you boot the machine, does it make any beeping noises..?
Usually, a single beep means all is ok. If you hear multiple beeps, then the bios is telling you about a possible fault and you should count the beeps for number and duration (long beeps or short beeps and how many of each and in what order)
Remove the ram and using some very fine emery cloth, gently remove any oxidisation from the contact pads to return them back to bright metal, then re install them making sure they are seated all the way down and the locking clips are fully seated too.
If you still have boot issues, I would suspect the ram sticks first and have them checked by installing them in another compatible machine, either a friends or at a repair shop.
I would suspect the board last so if the ram sticks check out as good, have a closer look at any other cards that may be installed, especially video cards and internal modems but also check out any network cards that may be installed..
If you are still not getting any display on the monitor, take the machine to a service centre or computer shop as they have the specialist equipment to check out the board electronically ( boot cards, scopes etc).
Let me know how you go and what you find..

1, 3 Reseat the memory, or replace with known good modules.

6, 7 Fatal error indicating a serious problem with the system. Consult your system manufacturer. Before declaring the motherboard beyond all hope, eliminate the possibility of interference by a malfunctioning add-in card. Remove all expansion cards except the video adapter.
• If beep codes are generated when all other expansion cards are absent, consult your system manufacturer’s technical support.
• If beep codes are not generated when all other expansion cards are absent, one of the add-in cards is causing the malfunction. Insert the cards back into the system one at a time until the problem happens again. This will reveal the malfunctioning card.

8 If the system video adapter is an add-in card, replace or reseat the video adapter. If the video adapter is an integrated part of the system board, the board may be faulty.

Dell Optiplex GX620 not recognizing PCIe video cards


Hello,

One of two things could be doing this:

1: Bad Video Cards
2: Bad PCIe slot(s)

If avaliable, I would test the video cards on a PC with a PCIe slot to verirfy if the cards are good/bad. If they work, your PCIe slot is bad and need to have the motherboard replace to correct.

Good Luck

Lenivo 3000 J series will not boot. Get nothing.


Check the capacitors on the motherboard, I have 3 units that did the same thing. See how many are bulging on the top, they should be flat.
Check the ones around the cpu or the video card slot.

Pc starts and runs but wont boot up monitor shows no signal


1) When you turn on the computer, watch and listen for:

a) power supply fan, (power is on)
b) chassis lights (power is on)
c) ticking sound during memory test
(the BIOS POST is running)

d) beeps or rhythmical error codes
(POST failed, bad CPU, CHIP set, memory or video)

e) Monitor either comes on, displays garbled video,
displays a No Sync or No Signal message...

No depending on how far it gets:

Check power supply, cables etc.
Check video cable.
Check monitor with a different PC

Now unplug the power cord, with the computer still
on, this will help drain any internal capacitors.
Wait 5 minutes, then shut off the switches,
and open up the box. try the following,
one at a time:

2) Remove all I/O cards except the video card,
and don't plug them back in until the problem
is fixed. Unplug all the ribbon cables from
the mother board as well:

Hard drives, CD drive, floppies etc.

Make sure you make notes about how to plug it
back in, and cable orientation !!!

0) Re-seat all power cables: Red, Black Yellow harnesses.

1) Unplug and re-seat the video card

2) Similarly, re-seat all memory SIM/DIM modules,

3) Re-seat the CPU

4) Replace the video card

5) Replace memory, CPU or whole mother board,

Plug the good parts back in one at a time,
and test the machine.

Save for the power supply, there really is NO way to test
and isolate a bad module except by swapping/ trial and error
because of inter-dependencies.

For example a bad I/O card, any I/O card, can short circuit
the I/O bus, causing all other plug-in cards to stop working,
or even the main mother-board to freeze during the POST.

A bad power supply ditto.

A bad memory chip ... ditto.

The type of electronic instruments required to actually
test modern computers running at Gigahertz speed cost
hundreds of thousands of dollars, some cost millions, and
are only available to hi end manufacturers

Even the power supply will not power up for a voltage check
if the mother board is bad, although you can use a jumper
on the green wire to ground to force it on, when you unplug
the power connector from the mother-board, if you are brave.

Computer shops carry a lot of spare parts, and their service
department has gutted computers rigged up as test jigs.

They trouble shoot your system by either plugging your
stuff into their jigs, one at a time, or by plugging known
good components into your computer until the problem
is fixed.

This if of course possibly dangerous, since one bad part
can also fry other good parts that plug into it, or that it
plugs into. The compute shops, of course charge you
enough to make up for this.

If a computer is partially operable, it is also possible to
run software diagnostics.

If not, swap and pray is the only way.

Hope this helps

Maybe video adapter


(I'd like to stress that this is mostly speculative. Please don't read this as gospel or a guaranteed fix; it's just an idea or two.)

True, it may be the video adapter. But there are a number of different things that can cause a computer to not display anything during its boot, even though you can tell it's booting. The best thing to try first is (and only if you're comfortable digging in a computer) unplug all the peripherals in the machine (e.g. HDD, CD, etc.) and RAM and (if it's an add-on card) the video card and turn on the computer. Obviously, it won't boot properly, but as you slowly add components back in (one at a time) you might find the culprit.
Basically, a problem like this can be traced back to either a short/static build-up in some component or a failing/dead video adapter. If you're getting absolutely no display (which your description indicates) it's definitely a hardware issue of some sort.

Of course, it really helps to have a P.O.S.T. card handy to determine exactly what's going on and most computer shops you take a machine to will have one. Often, local shops will diagnose a problem for free or a nominal fee.
