I purchased an Athlon 2200+ processor to upgrade my Duron 850.
My motherboard is a k7sem ver. 1.0. I went to the motherboard website and found that I could upgrade to an Athlon if I "flashed " my bios. I followed the instructions and the version on startup reads 1.2b. As far as I can tell this is the version I need.
I installed the new processor according to instructions with no real problems.
When the computer 1st booted I noticed the screen said Athlon 1500+........then the screen went black and never came up. I think my heart missed a beat.
Rechecking all my connections and thinking about what could be wrong I booted again and went into bios. There I went to the screen that sets the voltage and noticed it was set to default. After looking at the other choices I realized I need to change it to 133mhz/133mhz/33. This refers to CPU/RAM/fan voltage (I think).
Now I rebooted with with new new setting and the system came up!
I was a little disappointed that I couldn't really tell much improvement so I checked on some things. Sure enough, I discovered the computer now only shows 256mb of ram (8mb devoted to video). I have two sticks of memory installed 256MB each totaling 512MB.
Well my 1st thought went back to when I bought the computer. It came with a 256MB stick. I later added a 256MB stick. The stick I bought was a pc133. My thoughts were that the one that came with it was a pc100 and that was why the computer wasn't seeing it. ( remember my bios changes).
So I figured I was seeing no improvement due to my reduced ram and the solution would be to pull the old stick (pc100) and maybe go to a 512MB pc133. (I only have two slots)
Before I did that though I wanted to do some task on the computer to make sure that is all that is wrong.
Well problems started to crop up as soon as I opened windows media player. It would play for maybe ten minutes and then stick and completely freeze. Hmmmm....haven't seen that before. Went to RealPlayer and it froze after a few minutes. Don't remember that happening at 256MB ram when I 1st got it.
So I went to PCPitstop to let it anylyze my computer. I have gone to this site before and got some good tweaks to improve performance.
It froze the 1st 3 times. On the 4th it did anylyze the computer. Tried to print what it said but the system froze so what I am getting ready to write is from memory.
It said there was reduced performance on all drives. (I have C: partitioned into two (80GB) and one empty. (20GB).
Now I don't understand this so bear with me......it said the uncached test was 2.3 MB. and typical computers with my type configuration run 256MB. Now that is going into uncharted territory for me.
So there is my problem. System crashes after a processor upgrade. Sorry I went into so much detail but this way you will know what I have already done.
Hope someone can help me!
