I have an IBM NET VISTA MODEL 2276, CONFIG ID#Cf20495 i'm trying to fix for a friend. I've formatted the hd-clean. It has all the original components it came with. I try to load win2k or winxp, but the computer just keeps rebooting. If I load it with just DOS, the machine runs fine and everything, no rebooting. Soon as I start loading any win, it starts rebooting. Sometimes it will go through the install, and get to screen right before it flashes the desktop and reboots. Tried hotswapping parts, cpu, ram, hd. Nothing works.

I have stripped the all the cards, flashed the bios, and still does not work. Played with bios settings as well, but nothing. Keep in mind it works fine in DOS mode fine.

I had a problem like that a short while ago. There was something wrong with the hard drive. Try a Low-Level format if you haven't done so already. Good Luck.

Hi there,
try this:

1. use fdisk to remove all partition from the drive.
2. boot up with xp cd and use option format ntfs before loading windows.
3. watch the format process if it's not uniformly increased the volume, the drive is probably faulty.
4. use a different hdd to install windows.

There are around 20 different versions of the 2276 NetVista series.

The few I looked at should have no hardware issues with any version of Windows.

Has RAM been added to this PC?
I have seen several instances of RAM functioning fine in the POST test, and DOS, yet causes all kinds of problems in Windows.

If nothing else, try swapping the RAM with KNOWN compatible RAM.
(not all DIMMs work in all PCs)

there was some ram added, but I removed it in my first testing stages and put back the original sim, still doesn't work.

Usually if the computer continuously reboot, the power is the problem. However, when you load the dos, the machine runs fine. Try updating your anti-virus.

This could also be a memory problem because it happens only while loading windows. Try inserting the memory module to the other memory module of not available then try to replace the memory to see what happens.

I had that problem before and what I did was go to the bios and reset it back to the default setting and it solved the problem.

by hargoj

the bios default settings don't work at all. I have to turn off API, and I think its ACPM to make windows install.

What about switching video cards??? Or is that integrated?? Video card drivers are notorious for causing problems. You said that it ran fine in dos, so it seems you may have answered your own question in that Dos does not load the same amount of drivers as WinOS.Especially video.

I have had this exact same problem and it ended up being the RAM. You could have two bad ram modules. Try borrowing a friends or picking up a new module. This problem had me stumped for a long time, but trust me, it's your RAM. Don't waste any more of your time. Get new RAM.

Run a low level format and then run fdisk or partition magic..also i have used AefDISK..These all do the same thing, but i find partition magic to be the best...then re install the operating system, XP..

I have come accross this 2 times already, once with Win2k and the other WinXP.
Both are custom built machines.
Both were bad mother boards.

by hargoj

I have tried all of these suggestions... and it boils down to a new mother board... this is what I feared... I'm going to do one more strip down and hotswap rebuild, and then I'll keep everyone posted on what happens.... hopefully, not a new motherboard...
