Hi all.

After Windows has booted and my desktop loads, my screen starts flashing every few seconds and if I click the mouse a few times I will hear a beep and then the whole system will just freeze.

If I press the restart button on the front of the computer, windows loads fine and the system works perfectly. I can then restart the computer using the normal method (using windows rather than the physical button at the front) as many times as I want and the problem wont happen again.

The problem only happens when I turn on the computer from cold.

If I turn on from cold, then press the restart button when I see the first boot text, then windows will boot fine and everything is ok. This is an adequate workaround (when I remember to do it) but I'd like to get this problem sorted if I can.

One thing I've noticed is that when I turn on from cold, the windows logo will appear with the green bar thing and when that disappears, the moniter goes a coupla shades of black like normal but the mouse curser will take an unusually long time (maybe 10 seconds) to appear. When I boot with the restart button method the curser only take a few seconds to appear.

I tried disabling all startup processes and that helped because I could actually get to my desktop, but as soon as I start using any application....the same problem arises.

I am beyond my own abilities to help myself so I humbly turn this issue over to this excellent forum and give many thanks in advance to anyone who responds as this is my work/business computer and I really want it running properly.

Cheers.

What you need to do is boot to Safe Mode and when the desktop has finished loading you then SHUT DOWN (not restart) for a minute or so.

Now power on and allow to boot to desktop without interference.
Hi friend. I followed your instructions.

1. Turned on from cold and booted in safe mode
2. Shut down and left it for 2 minutes.
3. Turned on from cold and let it boot normally
4. It crashed.
5. I hard reset, it booted up fine....and I wrote you this message.

Weirdest thing. My computer only works when I reset.

Thanks so much for your time Jupiter, any other ideas?

Is there any way to see what were the last software I installed? I think I installed a few recently just before this problem appeared and I'd like to wipe them and see if that helps but cant remember what they were.

Cheers.

Go back to Safe Mode then Control Panel and uninstall whatever you feel is the problem but only uninstall those games or programs that you recently installed. In Safe Mode, the video output reverts to a VGA Safe Mode so there is not much video memory, about 64mb (not sure) so don't go playing any games while you are in Safe Mode.

Actually, it might not be any recent install but more likely that you are using a high tech GPU and motherboard (better with Vista or Windows 7) with XP.

It could be a PSU problem. What is your wattage on the PSU?
I already uninstalled a coupla programmes while I was waiting. Not is safe mode though, does that matter?

It was a game, Kingdoms of Amalur....and an image mounting programme called alcohol 120%. :whistling::angel:. Thats the only 2 I installed that I can def. remember and the problem started right after that.

Anyways....the problem persists.

Remind me again how to procure the wattage on the PSU my friend?

EDIT: I opened the casing and looked on the side of the PSU. It says...

AC Input - 115/230V ~ 10/6A 60/50Hz

Do you need the DC output? Cuz that looks a bit more complicated.

it's a number, followed by the word Watts. as in 230 watts
Ok, on the label is a table. The last row on the table says:

Max Power 165W 360W 6W 12.5W



EDIT: I'm clean of viruses.

EDIT: I forgot to mention that when I start up there are some red and amber lights on my motherboard that all light up and then they go away once it starts booting.

360 watts is not enough power to run an nVidia 9800 GT GPU. You need at least 550 Watts and a name brand PSU.
Hi spunk....

So do you think that after about 4 years of running a graphics card with a PSU that isn't adequate to run it, the actual card itself has started to malfunction?

Getting a new PSU you think might solve the problem?

PSU may fail at any time. Is this the only game or program that is suffering?
I dont have any games or programmes suffering my friend.

....as long as I hard reset my computer after I turn it on everything runs smooth as butter.

Its only when I turn on from cold and leave it, windows crashes as soon as I try and do anything.

Confuzzled. :confused:

Thanks for your time spunk. Is there any tests I can do to check if my PSU is providing enough power?

Is there any way of testing the GPU or the PSU to see if they are fried?

I've been playing games on this rig since the day I had it built and its been fine for 4-5 years. And its still fine as long as I reset the computer. Games run smooth. I dont understand why theres a problem only from a full start up from cold? Something involved in the cold boot is causing windows to crash that isn't present in a reset boot. What could it be?

I was having a google around and noticed some people with similar problems who ended up having mbr viruses. I used the tool they said cured it but it didnt find anything.

I may try a reinstall of windows before I start thinking about buying new hardware but it would be great to fix this problem without doing that.

Thanks for helping. Any ideas?

Boot up takes about 1.5 mins.

Just as fast as it ever was I think.

Can I just unplug or disable the video card or do I actually have to physically remove it?

After I remove/unplug it, will the PC switch to the onboard video out automatically or do I need to do something?

Thanks Jupiter.

After you've saved your new BIOS settings, turn the computer off, remove the monitor cable from the video card and plug it into your onboard graphics VGA port, then switch back on again.
Theres only one port my monitor cable will go into at the back of my computer.

Do I need to open up the casing and find a second port for the VGA cable inside somewhere?

So.....currently my monitor is connected via a VGA cable and is plugged into the VGA port at the back of my computer.

So you want me to switch the BIOS settings to use the onboard graphics and then unplug my monitor from the VGA port and use a VGA-DVI adaptor to plug my monitor into the DVI port which is the only other port at the back there?

Am I understanding you right?

OOPS! Motherboard: Gigabyte Technology Co., Ltd. Model EP35-DS3R
GIGABYTE - Motherboard - Socket 775 - GA-EP35-DS3R (rev. 2.1)

You don't actually have video out on the motherboard so you will have to use the GPU card for the VGA out so there should ony be the VGA/DVI option in the BIOS (possibly), select VGA.
I cant get into BIOS.....says it wants a password. I've never used it before. My login password doesnt work. What do I do?

My computer is deteriorating. It's starting to freeze, blackscreen, flicker even when I do a hard reset now.

Help!

You need to get a 650 watts PSU.
Ok but should we see if its the GPU problem first?

I think I would also try a complete reinstall of the OS before I started buying hardware.

The bios password would have been set by the previous owner of the motherboard as it is always set to disabled by default.

You could try a workaround, use password AWARD_SW but without knowing the actual name of the BIOS, it may not work.

You do need to get a better PSU as your video card requires 400 watt PSU
NVIDIA GeForce 9800 GT | Specifications | GeForce

If you don't run the video output on high settings, you might get away with what you already got.
The password didnt work.

So my options now are, get a new PSU and hope that sorts out the problem?

Correct?

Is it worth trying a reinstall of the OS first?

Even in safe mode I'm getting white screen freezes now.

I took my PC to a computer shop and he said the GPU was broken.

He's offering me a Nvidia GT 430 for $80. Is this a better card than the one I already have?

It sounds a little cheap to me and it doesn't look like the picture here: GeForce GT 430 | GeForce

The one he has is slightly different with a clear plastic hood and fan in the middle. Are there fake Nvidia's going around? I'm in asia so I need to be careful.

He absolutely insists that my PSU is fine to run my system with this new card.

Thoughts?

I need to give him an answer tomorrow. Do I need to insist on a more powerful PSU?

Thanks again.

Would I be best off replacing the card with the same 9800GT? Do they even make them anymore?

Whats the modern equivalent? I was very happy with it so I want a graphics card that gives similar performance. I'll have to order it....which one should I go for? How much should it cost roughly?

Thanks.

Just out of interest...if I was to buy the GT430, is my PSU ok to run that?

What are the major differences I will notice between its performance and that of the 9800GT? Just more sluggish gameplay? Are there any drawbacks non-gaming related?

Ok so whatever happens I'm gonna need a new PSU even though my computer guy insists my one is fine. Now that I think about it I dont think its 4 years old...I'm pretty sure its a replacement from a coupla years back. Anyway I dont wanna risk damaging any more components cuz of the PSU so I'll get a 600W unit.

Now I need to go in there tomorrow and figure out which card I can order. I'm in Vietnam so the choices are limited.

My budget is flexible..so I just want one thats comparable with the 9800GT. I'll check the order list for the Radeon card you mentioned.

Other than that is there a modern nvidia card thats equivalent to the 9800GT? I'm told the 9800GT cannot be ordered so no chance of getting that again.

I guess this is all gonna run me about 2-300 dollars. dammit.
