I have tried so many things to get this to work. Right now my computer wont boot. I have no display on my monitor, but i know it is working. My motherboard is giving me a red light. All this happened after I tried installing a new 1gb ram. So far I have tried resetting cmos, removing all ram to see if i get any beeps ( i get nothing with or without ram installed), I have swapped out my power supply. I have even moved my video card and power supply and ram to another machine with a different motherboard and processor which is where i am now. Before I switched to this computer I was getting similar errors except the light on the motherboard was green. I turn on the power to the computer and i can hear fans runing and the hard drives starting up. Please help!!!!

Please give us a little more information. The specs for the original computer where you had the problems.

MB?
CPU?
RAM?
PSU?
GPU?

The new RAM you tried to install?
The known working PSU?

Thanks for the info.

Having problems tracing the RAM specified, Please check the specs again, there should be more on the stick unless the label is missing...KPR comes up as Notebook, SO Dimm.


If possible, a picture would be useful.

Sorry, i can be more specific. the stickers say they are ddr2-800 pc2-6400 1gbx2 (above that they say f2-6400cl5d-2gbnq) When it was working I had two of those installed as well as the kingston. I had bought this pc from someone already built so i'm really not sure what that little one is. The one i was trying to install is very similar to the other 2, except it is 1gb (ddrii1gb pc2-6400 | f2-6400cl5d-2gbnq)

Hi.
The subject seems a little muddled so we need to clear things up.

Post #1, you said,

"My motherboard is giving me a red light."
MB manual, standby power LED, green on, or off, Cannot find any ref, to a red light.
Q. Where is the red light??

"All this happened after I tried installing a new 1gb ram."
Q. Did you have the 2 sticks of G.Sklill installed?
Q. Which stick of ram did you add, the Kingston standard length, or the Kingston short one?
Q. Have you at any time tried installing the short DIMM?

MB manual.
Always install DIMMs of the same CAS latency.
Supports 1 DIMM inserted into any slot, runs as single sided.
Supports 2 DIMMs, 1 matching pair in slots 1& 2 OR 3 & 4, duel channel.
Supports 4 DIMMs, 2 matching pairs in all slots.
Does not support, 1 a pair in slots 1&2 OR 3 & 4 + a single DIMM installed in any other slot..
*************
Post #5, Part of what you said.
"the stickers say they are ddr2-800 pc2-6400 1gbx2 (above that they say f2-6400cl5d-2gbnq) When it was working I had two of those installed as well as the Kingston.


Please clarify as this is different from Post #1. "
