the video card will show some improvement but if you're planning to run windows xp on it you would need 512mb ram for a smoother operation..

Black Screen

I am about to try a ATI RAGE 128 PRO 32MB PCI VIDEO CARD V44 just to see what happens .I know its below your recommedations but for something like 512mb they expensive.Any way my cpu can only handle up to 1.1ghz and the other video cards require a faster cpu . what do you think?.

lol.. let me clarify..

the video card you are getting to replace your current one is OK.

I was talking about your actual system RAM. You've mentioned in your previous post that you have only 256mb of RAM.. Although it is sufficiant to run windows, you'll be trading off a lot of features and some ability of your PC.. So in other words an addition of 256mb RAM would help you a bit in the long run..

Same problem but started when

Hi first time posting here amazing how many folks having my same problem just in different ways. I have the same problem but started when I added CTL 7Gx Monitor I can go to safe mode and it works great. Safe mode with networks work great. reboot normal mode and see every thing up to when it should go to the login screen screen go blank, BLACK, and you can see hd light working.

In safe mode click on display setting in control panel and the properties is grayed out so I can't open them. By the way this is a desk top not a laptop. well I'm doing this on my laptop but my desk top is the one having the problem. I'm I confusing you yet.

If safe mode works, then its a driver issue. If your monitor came with a driver CD then reinstalling the driver or updating it may solve the problem..

Otherwise try changing the refresh rate.. If you can't get in through the normal right-click destop>properties then try going to Control Panel>Display Properties>etc? You can try login as true admin instead of the normal power user admin, if you have that..

Although some words have a goust behind them. Like colored letters other then black have a shadow effect.but it looks cool kind of like it like that lol! Can't complain got the monitor for free. Thats right a 279.95 monitor for 0.00! Yah just can't beat that.

Hey guys.
I am also having a similar problem to the previous ones.
First of I was just typing up a word document and then the screen went blocky (Blocks made of sets of lines if that makes it any more clear most people don't understand what I mean as it is hard to explain.) I have had this problem many times before and I normally just have to turn of the computer, unplug the monitor and plug it back in. (I have always suspected that the Video Card was loose as this process moves it about a lot.)
When I turned the computer back on nothing had changed. The blocks were still there from the first screen. After this I took the card out and repositioned it but the problem was still there. I decided to try the monitor in the port on the Motherboard but the screen was just black. I took out the Video Card and tried again. This time I got a picture and it was working well.
Later on the same day I went back to my computer. I turned it on and it worked fine whilst loading but as soon as it went past the first Windows XP loading page it just goes black.
I have tried everything that I can think of such as going into Safe Mode and Enable VGA Mode.
When I go into Safe Mode it gets stuck on
"multi(0)disk(0)rdisk(0)partition(2)\Windows\system32\Drivers\agpCPQ.sy s"
When I go into Enable VGA Mode the same problem occurs (black screen)

If anyone has any ideas on what is wrong and how to fix it I would be very greatfull.
Cheers in advance.

Sounds like you should try (re)installing your mainboard chipset drivers, particularly AGP drivers.

Hello I have this black screen problem and I have been trying to fix it. I believe my problem is a driver issue, however I am unable to startup in VGA mode. I checked my device manager and it says I have VGASave. Device type: Non-Plug and Play Drivers. Manufacturer: Unknown and Location Unknown. It also says VgaSave is working properly. My comp was working fine until my brother downloaded a patch for some game and it required a restart. While I have all the Safe modes, I am unable to start with VGA. I have a AMD3800+ and Nvidia7900 GTX Card. Do I need to disable my Nvidia Card display adapter in order to go in VGA mode? Or is there a VGA I can download to enable it in my bios menu.

Windows will default to its generic VGA drivers (among others) when you access it from safe mode. In other words, you're already there.

Download the latest or most stable drivers from the nVidia website for your graphics card, and the latest Directx, then install it in safe mode

or

Go to device manager>Video adaptors and change/rollback the drivers from there,

I managed to find VGA mode. This is my issue: While I can go in safe mode, both VGA mode and normal both create a black screen after startup. I can't change the screen resolution or Hz rate in safe mode as trying to apply or save just resets it the next time I load. Any strategies to getting around this? I have tried removing and downloading new drivers for the nvidia card (just display only, can sound drivers also create this problem?). Anyone know what to do if VGA mode also gets blackscreened? Also I disabled automatic restart to see if I could read the error screen. It basically said that comp has shut down due to error and the technical code was:
** STOP: 0x0000007E (0xC0000005, 0xF61764BC, 0xF79F72D0, 0xF79F6FCC)
I'm not sure if that will help anyone recognize the problem but hopefully it might.
Thanks for the help.

You can try this Windows Repair.

How to: Repair Windows XP/2000 if you are unable to boot into Windows

This will default all your drivers to window's generic set.

I waited to see if the display came on and it reset after a while, giving a very short glimpse of a blue screen. At the moment i'm just trying to repair the Windows installation.

My specs:
Custom-built desktop PC

OS: Windows XP SP1
Processor: AMD AthlonXP 64-bit 3000+
Graphics: ATI RADEON 9600XT 256MB
Memory: 1024MB DDR400 RAM
Display: Tektronix 19" CRT Monitor
I'm in the same boat as you my friend. PC was working perfectly fine, and all of a sudden I was getting the explorer.exe file taking up 100% of CPU usage. I go to restart the PC, and haven't been able to get in since. Both normal and Safe Mode yield a blank login screen. In Safemode I can see the Safemode signs at the edges of the screen, but no login box. I don't think this is a video card problem.

if you can access recovery console with the windows xp cd then try it. Use the command sfc /scannow just incase that its a corrupted windows file.

do you remember what you were doing before/while this problem happened? and if you made any changes to your system?

ok I'm back. My issue was that I had a virus on my computer which wasn't allowing me to boot into windows.

I hooked up an extra hard drive to the system, installed an OS on it, and ran anti virus to clean out the affected drive. One of the files that the virus had affected was the kernel32 file which is probably what was really causing my issues.

The weird thing is that I wasn't really doing anything when I got infected. I was merely trying out a USB Flash Drive and a USB Mp3 player that I had just received in the mail. Quite strange, but that's microsoft for you.

black screen!

wow where to start... Im having similar problems to all the ones stated above as in the black screen first and foremost.. I uninstalled my onboard graphics driver cuz i wanted to install a new video card (geforce7900)...however, i found out i needed a new PSU cuz of the card's requirements...so i just tried to use the card just to see if i could quickly install its drivers.. anyway i turned the pc on and after the XP logo, it went into a blank screen. I've tried almost everything: VGA mood, safe mood wont work...as far as im concerned the old graphic drivers are gone and arent interfering (i dont see a BIOS setting for disenabling it)....when i tried safemood, it went thru a list of some sort and just froze at something.sys and then nothing happened...
Please help..i believe its cuz i uninstalled the onboard graphics and so the pc just has no video display drivers at all...how can i jus get my pc to run so i can install it back or install ANYTHING at all...please help!!!!

Must I run at 60Hz??

Hello all,
I was having a similar sort of problem with my computer, specs listed below:

[COLOR="Blue"]Pentium 4 2.8C
1.5gig DDR SDRAM (4 sticks)
Radeon 9800 Pro All-in-Wonder 128mb
Viewsonic VG1930wm 19" Widescreen LCD (Digital)
Antec True480 480watt PSU[/COLOR]

I got the black screen after the Windows loading screen and nothing seemed to help. Finally after reading previous posts, I tried booting into VGA Mode and it worked! Evidently, I can run the monitor at its native 1440x900 resolution, but as soon as I bump the refresh rate up to 75hz, it either freaks out immediately (screen is highly distorted) or it will repeat the black screen problem upon the next restart.

It seems that I am forever doomed to run this monitor at 60Hz. My question is this: I'm pretty sure both my LCD and video card are designed to run at that resolution and refresh rate, so is something broken?? Why can't I run at 75Hz??
Thanks in advance for any information people can provide.

I had the same problem, blank screen...here is my solution that worked for me:

Microsoft Knowledge Base Article 810092
http://support.microsoft.com/kb/810092/en-us



I had problems with WinXP Professional. I entered BIOS and changed Primary Graphic Slot from AGP to PCI..then my system started normally even if i have AGP graphics card.

I don't like Mrkfosoft Windowz
