Computer Won't Boot, Powers up, no screen, no beebs, no post or bios

I've been beating my head against the wall trying to figure this one out . I got some tips from PCWorld on how to speed up my computer. Kinda wanted to see if it would make a difference. So I changed the CAS Latency setting for my RAM from 2.5 down to 2. I also changed the Fast Command setting from normal to Fast or Ultra, can't remember. I left the frequency setting on auto. I saved the settings and rebooted the system. Once it rebooted, there was nothing on the screen. My monitor automaticly shuts off when no signal is detected. It never turned back on when it rebooted. No beep codes or POST beeps. So I turned it off let it sit for 30 min and turned it back on. The monitor turned on, but did not detect a signal. So, I turned the computer off again and cleared the CMOS. That did nothing. I turned it off again and reset the bios by removing the battery for about 5 minutes. Put it back in and fired it up and still no change. I also tried moving the RAM to different slots and also one at a time. Nothing. What can I do to fix this?

I Built my own system:

AMD XP 3000+ cpu
Soltek SL-75FRV mobo
VIA kt400 chipset
1 gig ram (2 512mb) PC2700 333MHz
350W PSU
80GB Western Digital HDD
ATI 9200 128MB video


I guess what I have done by reducing my CAS latency of the ram from 2.5 down to 2 is overclocked it. I pulled out the RAM and it said that it was rated for CAS 2.5. I chainged that to 2. Could I have fried the memory or the motherboard? If not, is there a way to reverse these changes? I can't get into the bios. Computer won't even boot. It just powers on. Please HELP!!!

I had trouble with short circuits with my board, just had to unscrew some screws and keep it off the back plate as my case was rubbish. Personally I would not except any advice from pcworld, there just salesmen if their was a chance for profit they would tell you to jump off a bridge. Goingback to your motherboard I hope you are warrantied because it's deader then the dodo your only hope is to get pc3200 ram chips (really fast maybe they can deal with the latency), lay your mtherboard on a unconductive service and power-up, throw it in the bin or call your manufacturer and see if it is covered for repair i was lucky mine was covered for three years, sent it back twice. got a new one now and the old one which is exceptionally good, although it f's up often.

Never listen to PC World, they dont know what they are talking about.

The cause is because you changed the cas latency of your ram. Your ram obviously cant support it. Motherboards select the relavent latency for your ram.

The ram is unable to operate at these settings, therefore this is going to be one of the reasons for the problem.

Take out the battery on the motherboard, leave it for 10 minutes and put it back in. You will then be back on default bios settings.

Running cas2 on your ram may be possible, but you need to give the ram some extra voltage.

This should fix your problem

Be sure to unplug the computer when you do that...

I did read right, you did initially take out the cmos battery for a duration, because this will default your system settings, otherwise follow my previous advice.

Ok I went to my friend to fix his computer because it was very slow... so i tried to reinstall windows but the DVD rom was not recognized by BIOS so i changed the IDE cables and everything was ok. but still the problem so i went to BIOS to change boot device to DVD rom and restarted the computer and then happend the same thing it would not get up i tried to reset cmos nothing. reconnect all cables several time. i can just see light on the front and a sound from hard drive thats all.

All I did was install 3dmark 06 but was getting a problem with dsl so I shut down not restart and same thing.. every thing is on but black screen... I run stock no OC.. don't know how to do it....
So I unplugged it, took battery out, changed the jumper, now waiting to hit reset on MB DFI LanParty UT F4 Ultra-D running cosrair ram 2k twin that it is called for...600w PSU enermax 12v


If this doesnt do it I just don't know..

webej, I don't understand that - was there a question in there somewhere or were you posting what you were doing in this situation ?
