Failing to boot Windows

[StevenNevets]

When I turn on my computer, it will turn on just fine, but it fails to boot Windows. By that I meen it'll go through these cycles... first trying to start windows, then restarting, and then directing me to a black screen with options for boot normaly/safe mode/last known good configuration.
I pick start windows normaly and it ussualy works after that, but no always.

I've had the problem for months and still havn't figured out why.
`I had the problem on and off since I built this.
`I've done Windows Repair and that had no impact.
`Once the computer is up and running it works perfectly.
`It's not bad-caps.

What could be the problem?


Oh and it doesn't fail to boot everytime... There also seems to be streaks of succesfull boots and failures (will work a few times in a row and then fail a few times in a row or 50/50)




The only problems/solutions I can think of are to flash the BIOS or replace the RAM. Which one is safest/worth trying first?

That's usually a sign of a bad/going bad power supply, but I wouldn't suspect that, with the power supply you have, and the components you're running. Are you overclocking your cpu? That type of thing will happen with a DFI board, if you are giving your cpu quite a bit of vcore, but leave the Startup voltage on default.

No, I was planning on overclocking this at one point, you could probobly tell my some of the choices but I decided not to.

I havn't messed with the bios at all, besides the standard windows/drive deal.

Troubleshoot by disconnecting unnecessary peripherals including all USB devices except items you need to boot properly like hdd. You can even remove add in cards except for the video card. Disconnect all optical drives, and extra hdd. If you can boot properly then it is a psu problem. The reason why is by disconnecting unnecessary peripherals you reduced the starting current of the system. It is during this starting phase that current surges at its highest. If the problem is still the same, try switching the rams (assuming you have at least two sticks) one at a time.

You reminded me of something. What RAM do you have (Steven), and how much voltage are you giving it? Half of the DDR2 RAM being sold today requires more than 1.8v, yet nearly every motherboard only defaults to 1.8v of vdimm. Oh, and congrats on your 3,000th post, Jiggz.

Here a link to my ram.

They are all supposed to be decent (quality wise) and are known to be compatible with each other... Yet it seems like one of these must be causing the problem somehow.
