Text substituted by other letters during boot

Specs: Windows XP, 1GB
Many weeks ago, I accidentally switched off my computer main switch while running a 3D app (improper shutdown), after rebooting it, everything seemed fine, but when I once again run the app, it all crashed (blue screen).

When i rebooted it, the text during boot up, many of the characters seem to be substituted by other characters. I took a few pics to show you exactly what I mean.

Booting up .. http://i26.tinypic.com/2q0prvb.jpg

MY nightmare began, I have flashed my bios countless times, my computer can be booted into my windows main screen and everything works perfectly, I can surf the net etc etc.

But when I try to install my graphics driver, during the end of the installation before it is completed, it will crash. I suspect my graphic driver has gone bad but the funny thing is if I do not try to install it, everything works fine, of course I am unable to run 3D apps.

the corrupted on-screen text during the boot process suggests that the graphics card itself is faulty, not the driver.

Yes, definitely a graphics card failure. The installable drivers plays no part in the BIOS display. That uses basic drivers that are incorporated into the BIOS. Just a plain text driver which is all the BIOS is required to display and hardly ever goes wrong.

Okay new problem...on a cheerful Saturday, I finally had the mood of repairing my computer...I flashed my bios version by version..until the most recent BIOS update AND MIRACULOUSLY the problem is fixed!!

now the problem is the CMOS battery!! (its quite a new battery but I have used it before my computer was fixed) [sorry but I don't really understand the function of the battery, my understanding is it keeps track of time and date]

my problem now is when the battery is out, everything in my computer is fine..except an error message in boot up which can be skipped.

But once I put the battery in, my screen goes black and when I boot up, the problem mentioned above comes back..so any ideas? Rather annoying not able to see the time LOL..

AND!! I can play 3D games perfectly fine without crashes =D WITHOUT the CMOS battery of course!!

That is just one of its functions. The battery powers the CMOS memory which stores information on the hardware in the computer, hard disk type and sizes, memory configuration, timings and a host of other things.. The CMOS memory is only 64 bytes long but you can get a lot of information into 64 bytes.

When you replace the battery you need to go into he BIOS and reset the settings and save them and re-boot. Without the battery the BIOS will just use fail-safe defaults which may or may not be the best for the hardware you are using..

To get into the BIOS you press one of the keys on the keyboard as soon as anything appears on the screen and before Windows starts to boot. The key to press is usually displayed on the first screen, "Press Esc to Enter Settings" or something similar. You manual will tell you which keys to press to get into the BIOS. Est, F1, F2 or F10 are all possibilities.

You need to keep tapping they key until it reacts, press and hold wont do it. By the time you get to the screen in post one it is too late.

I mean I know how to get into the BIOS, in my case it is the DEL key, but after getting in, how do I reset the whole thing? Load Optimized Defaults? Is that the one? Now I got a new problem, after I put the battery in, my computer crashes and the 1st problem comes back, but now even after removing the battery, the problem is still there!! My temporary is gone!!!

Optimised Defaults should do it but check the clock is showing the correct time. The disk drives are there and recognised and it is configured for the correct video adaptor.

Dont forget to save you settings before you exit. Then reboot.

You should still be able to see enough to reset the BIOS. If you could see enough to recognise Optimise Defaults then there should be enough for you see other things and save them.

At then end of it all I still think you are going to need a new graphics card.

Yes..I do need a new graphic card...but the biggest question now is..my computer works miraculously fine WITHOUT the CMOS battery, but with it, crashes happen..LOL..I really have no idea how the presence of the CMOS battery create crashes.zzzzzzzzz..

Anyway, it'll serve as a temporary solution, my 3D games are running fine now =D
