  1. hey, whats up i just joined the tech spot forums and
    well heres my case if anyone could help me i would greatly apreciate it
    ok well i went to newegg and bought almost everything i dreamed of haveing i got:
    Thermaltake|XaserV VA7000SWA - case
    pentium 4 550 3.4 GHZ - prossecor
    2 Western Digital 250GB 7200RPM 16MB sata II - hard drives
    GIGABYTE GA-8I955X Royal Socket T (LGA 775) - mobo
    OCZ Gold Series 1GB (2 x 512MB) 240-Pin DDR2 SDRAM Unbuffered 667 - memory

    and i already had a X800XL gfx card but any way im really happy when it all got here like last week then i hooked it up (it was my second time building a pc) and every thing is cool then it doesnt recognize the sata HDD's so i go get the drivers and put them on a floppy and instal them wit windows it all went good so i had to format the drives to instal windows and it stops at 89% then says "Formating failled Please restart" so i tryied again and it got to 96% then the error, so i figured the third time was the charm so i tried again and it froze at 55%...and i was baffled :confused: so i shut down and started up and nothing happens no beep, no bios, just fans spining and the hard drives going at it along with the dvd drive so i keep trying to get it to work for a week. unplug everything redo it all...nothing then i saw this post and did what Jevond said in another thread helping someone else. about takeing the memory out and the pc beeps like constantly then stops and does it again but still nothing on the screen..so if someone could help me they would be saveing me alot of money and time please help

    Ok...

    OK.. First Take the system apart strip it down to nothing. take the Mainboard, Videocard and RAM Plug it all in and let it post; set your BIOS and CMOS settings once you got them set (making sure your RAM is setup properly).
    Ad your HDDs and ROMs. Rebood again without installing an O/S get the settings for all this up and running you know they are running when you see the "No Operating System Found" error when you get that then install your O/S.

    Tip go on line and get the newest BIOS for your Motherboard and install it as soon as you get your system to first post.

    What kind of PSU are you using (total watts, amps on the 12v rails (s)) and what about the HSF on the CPU? Is it OEM? Did you use the correct amount of thermal paste? Too much will actually cause overheating as it insulates rather than transfers.

    Follow Secondgumen's advice and if it doesn't POST I'd suspect your CPU/HSF combo is screwed up somehow. If it POST's fine and then fails after you start adding drives and RAM it is probably the PSU.

    Did you strip it down like SecondGM said? Specifically, did you disconnect both Hard Drives (both power and data plugs) and the optical drive (and floppy if you have one)? That PSU is no powerhouse as it only carries 18 amps on a single 12 volt rail but it should POST a striopped down system.

    i disconected everything then redid the front panal things like power switch all those made sure they are right. disconected everything from the psu then just conected the 20 pin power plug to the mobo and the 4 pin cpu power plug to the mobo put the ram and gfx card back in and it didnt work no post screen...its so wierd

    Drew-
    Unplug the PC from the wall. Remove the CMOS/BIOS battery and if you know how, use the CMOS/BIOS reset jumpers. Usally it is a blue cap covering pins 1&2 on a 3 pin set and you move the cap to pins 2&3. Leave for a couple minutes and then move the cap back to pns 1&2. Replace the battery and plug the PC back in. Start it up and see if that works (leave it stripped down for this procedure).

    The reason I thinkk this should work is that you should be getting at least one beep from the mobo when it starts telling you everything is OK or a series of beeps telling you something is wrong. You remove the RAM and the mobo recognizes that and beeps accordingly so the system is working. in some ways.

    You have a bad component Drew. Stripped down and with a reset CMOS/BIOS it should POST. It is either the PSU (power is flowing so I don't think so any longer) the CPU (distinct possibility it is faulty) RAM (small possibility) or the mobo itself (this is what I'd lay money on). Just to be thorough and to avoid a loss of more time on a bad RMA you should test the CPU, Video card and RAM in a different system to ensure that they are good. If that isn't possible I'd RMA the mobo.

    Hey, im pretty sure the problem is either the mobo or the memory. why not the cpu? well, its an intel and i have seen only 1 damaged intel cpu in the last several years. what chipset is on that mobo? i recently heard that via has some problems with some of the new technologies like sata II. oh yea, and with that 420W, unless its enermax, i think you will have some problems running that configuration. oh yea and there is also like a defect in a few mobo series. asus p5s(not 775 socket) and i know that gigabyte had some defective series about a year ago so it could have happened again. let us know what happens and good luck...

    ps if you are running dual channel, make sure you read the mobo booklet to see exactly what memory you can use and if its double sided or single and in which banks.

    hey ya i think your right its either the mobo or the memory but really im not hearing good things about my psu. but my chipset is intel 955X and it says it can do dual channel in that manual but il try just one stick of ram and see what happens.
