Flaky video can simulate bad CPU cache

[theBeast]

Here's something to keep in mind. I just ran into this:
The customer's config is a Cyrix 200 w/ 32 meg DIMM, ATI 2 meg 264 video, and a PC chips mobo.
Customer complained that Win 95 would hang at the logo screen. I booted the computer, and it would hang before the "Starting Windows 95..." message.
I've seen this problem 1,000,000 times, and 99% of the time, it's attributed to bad cache. So, I immediately went into the CMOS and disabled both External and Internal caches. Booted, went into Windows fine. Reset the computer--it hung with no video. I turned it off for about 5 minutes, turned it back on and went into CMOS again. Enabled External cache, and rebooted. It went into Windows fine again. I rebooted, adn again the system hung. I turned it off for 5 minutes, went back into CMOS, enabled internal cache and the system hung right before Starting Windows 95...
Chalked it up to a stinky Cyrix CPU.
I rebooted the computer, disabled internal cache, and decided to do other tests on the computer to see if there was anything else funny with it. I ran a 3D testing program and the system hung. I pulled out the video card, and put in a known good one, and tested--it tested fine. It turned on CPU internal cache, and the system runs like a dream...well, a Cyrix dream. http://www.windrivers.com/cgi-bin/forum/smile.gif

I didn't do it!

Actually, it WAS you! I saw you sticking your head in the computer with a magnetic screwdriver saying, "I wonder what would happen if I touched this..."

Nobody ever said the problem was a PC shark (-;

Poor BadCache!

Sometimes things are going pretty weird on a system. You try to fix it but you just can't. There's an alien force, an alien dyne that's preventing you from fixing it!
It's strange, but I use to call it Aliendyne!

look at the hardware, that has to be the ****tiest setup i have heard (this year)
no wonder you are having these probs, get some real hardware.

[theBeast]

Yes, I know it's a crappy computer. I just fix them, though, and we didn't sell this woman this computer. If the customer isn't complaining about anything else, I can't change anything else.
