Hi, I'm new to the forum. I got home last night and the computer was on, but the screen was blank. It won't boot up and the status light on the monitor blinks like it's not getting any signal. The past few days, the computer's been freezing and locking up with increasing frequency. I suspected overheating so I cleaned out the dust and the temp monitor read normally. Now when I turn it on, the fans and drives start up normally, but that's it. Nothing on the monitor. I made sure all the cards and memory were seated properly, to no avail. Any ideas? Did I blow the CPU or video card? Thanks. :confused:

Substitute another video card and it "should" work... ;)

Sounds like it's booting up but you just can't see it because the screen is blank. Try your monitor on another computer just to be sure... :)

You need to check 3 things.

1.)Video Card

2.)Video Card

3.)Video Card



Everything is pointing to the video card ;)

Thanks for the feedback. My curiosity brings another question tho. How do I know its the video card and not the CPU? If the card was bad, wouldn't it boot up with the standard drivers? Thanks

You have to either put that video card in another computer, or install a new video card in this computer.

No if the video card was toast you would boot without any display and there would be a series of long and short beeps. If your computer seems to be booting (fans spinning, drives active, etc) then perhaps it’s a checksum error try clearing CMOS and see if that clears up things for now. Then check the voltage reading on the CMOS battery if it’s less then 75% then replace it.

Well, I've made some progress of a sort. When all else fails, read the directions. I checked the MOBO manual and discovered there are diagnostic LED's on the USB bracket. Who knew? The LED's indicated a problem with the CPU either malfunctioning or not installed correctly. I re-seated the cpu and whaddaya know the computer booted right up. I can't imagine how it got unseated in the first place, but whatever. Unfortunately, the computer doesn't work today. It starts to boot normally, going past the Windows start-up screen and all until it gets to where background color appears. At that point before the icons show up, the screen goes black. It will complete the start-up in safe mode, yet the device manger doesn't show any problems. The other difference I noticed last night, playing SimCity is a lot of black dots(pixels?) that appear randomly on screen. If it was an LCD display, I'd think dead pixels. Today in safe mode I notice random patches of yellow in the device manager menu. Did I fry the graphic card?
Thinking ahead, if I did, what's the better choice, ATI or nVidia? Thanks

I saw the pointy shoes and hat, it should have been a dead giveaway. But the cookies were real good. I run Windows 98SE, no "last good configuration" option. Thanks

If you go back and re-read your original post, you had freezing/lock up problems and tried to clean out the machine - this could have been when the CPU got screwed up....

You've managed to get that straightened out, but it sounds like you're back to square one.

Sounds like it may be time for a clean install of Win98SE. This could serve two purposes: straighten out the lock ups, and more importantly, with a clean install, ensure that those lockups were due to software issues and not a potentially permanent hardware failure. (if on the clean/bare install you still have issues, could point you in hardware direction).

Just my two cents,

MBN

Also, try this. In the option where the safe mode is, choose enable boot logging. Then boot into safe mode. Look for the bootlog.txt file. Copy it and post it here.

Hope your problem is fixed! Will be waiting for your reply!

Well, I'm making some progress. The problem was in fact the graphics card. i re-installed Win98and replaced the card with a Gigabyte Radeon9600XT and the computer boots up every time, so far. my next question is how to get rid of the remnants of the old drivers. I uninstalled every thing to do with nVidia and removed the nVidia display drivers from the Device manager before installing the new card and drivers. Now when I boot up, windows looks for a device file "C:\WINDOWS\system\VMM32\enable.exe" I'm assuming this is related to the old graphic card because I find the nVidia display drivers still listed in the Add/Remove Programs list, despite the fact that I removed them. I tried to remove them again and the computer won't let it happen. Any ideas? and how do I get rid of the warning message about the file? I'm thinking there's something left in the registry or INI file? Thanks

If you know your way around the registry then that's the straight forward way to go. I think you'll be a lot happier with that ATI card ;)

This is not always the case. It all depends on the set up. All of his/her symptoms pointed to a video card ;)
