Old PC 486 Booting Problems

I have an old PC486 that was working in good conditions with Win95 installed last week. It has 32MBRAM that is the maximum for 30 SIMMS memories in its motherboard(8x4MB). I acquired 8 30 SIMMS with 8MB and installed them. Turning on Win95 stopped. I re-booted and it would only check 32 instead of 64. I heard two long beeps. Turned it off and replaced the old memories back. Now when booting I can enter the BIOS but the screen is distorted and flashing the text making it unreadable. What should I do to fix this?

Here's a site that lists BIOS beep codes. My first guess is that your SIMMs aren't fully seated.

What brand is your BIOS?

Commented:
If it is a Phoenix BIOS, "Any combo of beeps after two means that some of your memory is bad, and unless you want to get real technical, you should probably have the guys in the lab coats test the memory for you. Take it to the shop."

For AMI, two SHORT beeps means, "Your computer has memory problems. First check video. If video is working, you'll see an error message. If not, you have a parity error in your first 64K of memory. First check your SIMM's. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard.

If the SIMMs aren't all the same brand and model, be sure you are installing like pairs together. If this doesn't fix it, try giving us the brand and model of your motherboard, or at least the FCC ID number.

Don't be offended by the obvious suggestion:  Did the video card or cable come loose while you were operating on the memory?  Remove and reseat the video card.

Commented:
Only the suggestions he's already thought of are obvious.
