I purchased a L2 pb cache upgrade for my Dell Dimension XPS100c...the module was from VisionTek, it was supposed to be 100% compatible with my system.  My computer won't get to the post beep.  The monitor goes to energy saving mode as if its getting no signal.  I've checked my system bios and it is the most recent and compatible with the cache upgrade amount (512k).  I've taken out the memory i've upgraded and it still doesn't work.

What I want are suggestions as to possible conflicts.

Thanks,

Sounds like you loosened something else up in the process of performing the upgrade.
Did you check ALL of your cables and connections on the motherboard?  Does the power supply fan even come on when you power up the PC?

JR, I did not.  I replaced the old 256k cache chip and the system works fine.  I take the old 256k cache out and put nothing in and the system boots up.    I put the 512k upgrade in and it does not boot.

PS, everything spins up, hard drives and fans, when i power it.  So my answer of "i did not" is that i did not loosen any connections as proven by swapping the original cache back in.

I was not implying that you intentionally loosened up any connections.  It generally happens by accident.
Disconnect the power to the motherboard, then re-connect it.  Then check all connectors  inside the computer.  HDD, Floppy, etc.. AND remove and re-install all your cards on the motherboard-- Video, Modem, ETC.
That will be the only option outside of your motherboard getting ruined by ESD, or some other sort of problem.

JR, You'll have to explain your last answer to me in the following way:

Why would I have to reseat every hardware device when the 256k L2 cache card works fine?

It doesn't make sense to me that by reseating every hardware device I could get the 512k L2 cache card to work when the 256k L2 cache card works every time I put it back in.

I'll await your answer because I'm not about to reseat everything untill it makes sense to me.

My orignal request was for suggestions as to possible conflicts.  You have not stated any.  You have only told me to take action without the explanation, which I will refuse to do until I understand the "why".

The 256k cache module works EVERY time it is in?
Sorry, I misunderstood.
I was thinking that nothing works anymore..
NOthing works when the 512k cache is installed?
Generally there is a jumper that you'll need to change to insall a chache upgrade.

JR,

I've looked through the manual and there were no jumper settings for cache.  I then went to the system manufacturer and asked and they told me the cache would be recognized automatically.  I've checked this by removing the 256k cache and booting up and seeing that the bios screen reports "no cache" and then reinstalling the 256k module and then the bios displays "256k cache". (powering down in between, of course)

So, no jumpers.  bummer.  Is it possible that the video bios could be conflicting?  I don't understand the relationship between system bios and the video bios but I'm wondering if this could be the source of my problems.  My only reason for thinking that is that the monitor never sees a signal, ie goes into energy saving mode.  Of course, as I stated before the system never gets to the post beep.  In fact, the only sound of powering up is the spin-up of the hard drives.

Sounds to me like you have a bad cache module, that's the only thing I can see possible.

If it is known to be good, then I must say that it is incompatible.

Ok, Thanks JR.  That's what I'm hoping I can prove and return it.

Hope you don't mind the grade, but, it didn't surpass my general knowledge.  I actually had already looked in the manual for the jumper thingy but once you suggested it I took it to the end.

Thanks for attempting to help me.
