trouble installing devices

I am building my first computer and when I got it all assembled and tried to load wondows it only gets as far as installing devices. It gets about 60% through and tha screen scrambles. I have tried removing all devices but the mother board and the graphics card. Anyone have any ideas where my problem might be (or how I can check the MB or Graphics card)?

Please post your system specs. What ram are you using? Check to see that it is properly seated. tyr running memtest to verify the ram.

Yes, a poor quality unit can cause all sorts of problems.

Well I can't find the paper trail on it but I know it was about $150 on sale. I just can't remember who I bought it from. I was at work so it should be in my mail there but I don't go back to work for a few days.

Open up your case and see what it says on the label off of the PSU.

I cant without removing it. The label is on the top. the rest of the case is transparent. Its a logisys.Model PS550AC.
Strike that price too. It was about 150 for the ps and the case. An aspire mid tower. the one with the temp and fan speed gauges on the front.

Read through some of the reviews on Newegg.com for the PSU and a lot of customers say the unit runs a little weak on the 12v rails.

Not sure I know what that means. 12V rails? I understand the weak part. Do you think it could run weak enough to keep the system from installing windows?

If I can recall, a weak 12v rail can cause system instability. Not sure if I remember correctly though, one of the other guys on here probably can confirm or correct this fact.

I never used LOGISYS brand PSUs before either, so I don't know if they are quality ones either. Truthfully, I never even new they made PSUs. But it does sound like a PSU issue to me though.

If not, it could be (in this order) overheating, faulty memory, bad HDD, or some type of hardware conflict to name a few possibilities.

I think I've eliminated memory. Overheating shouldn't be a problem as its only on for a couple of minutes. But thanks for giving me some direction to go. I suppose the only way to check the other devices is to replace them. I know a couple guys at work who are more into building then me. Maybe they have parts I can use for testing. If not I guess I'll just have to find a local store with a good return policy. Thx again

I would swap out the power supply first though. I really think that is the problem.

A good PSU will usually have a strong +12V rail or even dual +12V rails.

Plus a quality 550w PSU will usually cost over 60 bucks at least. The LOGISYS PS550AC PSU that you have only cost 40 bucks.

You are flirting with danger there. That is a very cheaply made power supply and it is NOT ATX 2.0, which is required for your build. It makes NO sense to spend $1000 on a CPU and try to power it with a $25 piece of junk power supply (yes, $25 - the clear acrylic case adds $15 to the price of the same model in metal).

I'd get something like an Antec Truepower 2.0 or Fortron Blue Storm unit.

GLC,
I just bought the Antec Truepower II ATX2.0 480W and, so far, am very pleased with it. Plenty of connectors, wires are more than long enough to reach and the 20 pin plug that adapts to 24 pin. Easy to install and the only minor hiccup was a stupid move where i misconnected the 4 pin plug to the mobo. Fortunately nothing happened.
Sorry did not mean to hijack this thread

I wouldn't call it hijacking. It just seems to be evolving into a discussion on power supplies. So far it seems to be the consensus that that is where my problem lies. Thanks for the input. I have been looking for a more compatible power supply. I am hoping to find one with blue lights but all the ones I have looked are either too noisy, have poor fan relability, or a questionable 12v rail. oh well. I'll take functional to astetic anyday.....

Yes, functionality/quality should be weighted for about 99% of a rating, if you were rating at PSU. Generally, PSU's with flashy lights are extra useless stuff tend to be junky (the flashy stuff is what sells them). I'll take a plain boring PSU over a flashy junker any day as well.

So would the
Antec TruePower 2.0 TP2-550EPS12V (TPII550EPS12V) 550-Watt Power Supply
be considered a atx2.0. Details list it as atx 12v or should I keep looking for something that actually says ATX 2.0 in the specs? Sorry I did say this was my first build.

Yes I think they are ATX 2.0 compliant.

what if you tried another graphic card? and reduce to 1 stick of memory. Other than that you may need to look at the mb. Is the cpu installed correctly?

Don't have one handy is the problem. Thinking of going to a computer shop and getting a cheap card just to see if I can eliminate the graphics card. unfortunitly I work 6 to 6 so just about everythings closed when I get out of here. I wont be able to put in serious time until Sunday. Chip should be ok as it boots and starts to install windows. I wouldn't think it would get that far if it was installed wrong. Thx...

Ensure that you have those "pins" on the heatsink fully snapped in. Those can be a bugger to get in (requires out of case assembly). What does BIOS say about your CPU temps? not to mention that EE CPU puts out a ton and half and then some of heat.

Is the PC just rebooting and crashing or is it still doing the scrambly thing? If it's shutting off after running a while it's possible the CPU is overheating and shutting to prevent damage, but I don't think that would cause a scrambled screen.
