I am seeking advice as to what is going on with my computer and how to fix it. Every time I press the power-on button the computer starts up, all fans spin up and the computer turns off almost immediately, but then cuts back on after about 1 more second without me pressing the power button, and proceeds to boot normal, everything works fine and has worked fine for 2 years...however today I am reformatting the hard drive and installing a new OS (Win7) because the comp is getting slow and I would love to fix this problem so that I don't standby my computer every time b/c the 'start up, stop, start up' makes me fear my comp is shorting out or something. I read some posts and heard it may be the BIOS which I had to upgrade when I built the computer to adjust RAM speeds and make some other tweaks so that all the components were working as intended instead of running at slower speeds. I think I dropped a screw somewhere in the comp while building and I had already screwed almost everything into place and was too lazy to remove mobo and search for the tiny thing. Can anyone identify the cause of this problem?
We need to know what's in the computer. Without knowing anything about the actual parts, it's impossible to even begin troubleshooting.
Have you tried everything in the "Read before posting about boot problems" sticky? If not, go through every step. Come back and let us know what happend during the steps. If you have already done everything, did anything change?
This type of problem is often caused by incorrect settings in the BIOS, specifically RAM voltage and timings. The system tries to boot with values that don't work, fails, and re-tries with "safe" default values. What exact RAM kit do you have? You said you set the RAM speed in the BIOS. Did you also set the timings and voltage to the correct values?
OK I would really appreciate some help with my ram timings/voltage because after looking through the bios for the first time in 2 years I am extremely confused!
In the BIOS:
FSB Frequency is set to 333
DRAM Freq. set to [DDR2-1066mhz]
(Many settings following set to [Auto]
1st information: 5-5-5-18-3-54-6-3 (this is all determined automatically at the moment except for the beginning 5-5-5-18 (CAS# (5), RAS# to CAS# Delay (5), RAS# PRE Time (5), RAS# ACT Time (18)))
2nd Information: 8-3-5-4-6-4-6
3rd Information: 14-5-1-6-6
Thanks alot for your help shortstuff &MadAdmiral, somehow my computer no longer has this problem after i changed the timings from their correct ones, put them back, and changed the boot order of the pc (to install my new OS)...now it starts up as it should! the RAM voltage is set to 2.10v right now...should I bump it to 2.20v for performance?
