Windows 7: New build not booting

New build not booting

So I built this computer about 5 months ago and it would start to boot, and then shut off. I posted about it here, and someone said that the mobo was probably fried. Well, today I finally got a new mobo and threw it in there. It booted up the first time, all the way to the "Please insert boot media" message. I put in the Win 7 DVD and restarted the comp. It started to boot, then immediately shut off. Same problem I was having last time. I know the mobo is good, because I took every precaution I could while installing it. I'm thinking that, even though the CPU cooler is running...the CPU is overheating. Could it be a lack of adequate thermal paste that is causing the issue? Any ideas are appreciated.

Overheating would be my first guess too, but it isn't the only thing that might cause that. To check for an overheating issue, there should be a "PC Health" zone, or something like that in the BIOS. Check to see how hot your CPU is getting first, and we'll go from there. Also, make sure your CMOS jumper isn't shorted. Most boards won't even fire up with it shorted, but some do, but then shutdown shortly after firing up. If you find that your CPU is getting hotter than the shutdown temp that's set in the BIOS, you may have to raise it slighly, or even disable it, until you get a better heatsink [if it isn't dangerously hot]. Read the boards documentation meticilously.

The only problem is...I can't even get to the bios at the moment. I'm planning on just running down to Fry's tomorrow and grabbing some thermal paste and seeing if that helps. If not, I may try swapping out my cooler from this comp to the new build to see if that helps.

If your saying your not using thermal paste at all, then of course it's an overheating issue. Don't even attempt to run it like that. You will probably end up toasting your CPU.

No, it has some thermal paste on there, but as I was installing the cooler, a bit came off on my hands. All that was on there was what was already on it from the factory.

That's not unusual. Most people over do it with the themal paste anyway. Thermal paste is only a filler for the microscopic peaks & valley's between the CPU, and heatsink. You only need a dab. What hardware do you currently have hooked up to the board? Try to get into the BIOS to see your CPU temp with just a single memory module installed [no HDD(s) or optical drive(s) hooked up].

I have a 7200 RPM HD, optical drive, 2x2GB DDR2 RAM sticks, Geforce 8800 GTS and a multicard reader. I'll work on it some more tomorrow, gonna crash right now.

By way of agreeing with Mad Max....


This sounds like it might be hardware initialization errors...

When the system starts up is there any beeping from the internal buzzer/speaker?

You have one good clue... it's done this with two motherboards, so it's not likely the mobo itself... could be disks not spinning up, memory not fully seated, CPU problems, power supply...

For first boot I always minimize the hardware. Imbedded video, sound, etc. keyboard, mouse, 1 memory strip, 1 hard disk, no optical, no accessories... The only goal at that point is to get into the BIOS settings so you can configure them.

Then, as the build progresses, I add video, sound etc. each in their own restart of the system... That way if I run into problems I know what caused it!

One trick for the really stubborn ones --and I know this isn't kosher, so proceed with caution-- is to remove the CMOS battery, start the system up and let it error out on BIOS initialization. You should get a message saying "CMOS settings bad", "Press Del to enter setup" and some boards will even take you directly into the BIOS when that happens. Once in the BIOS put the battery back in... do your detection and settings, then reboot.... on about a 50:50 basis this fixes the problem for me.

I don't know if anyone else has noticed this but of late I've had a whole string of boards (mostly ASUS) where the CMOS checksum is bad and the thing won't start. The battery trick has almost become SOP with those boards.

Are you using the stock CPU heatsink? Is it mounted properly? What color was your thermal paste?

Just use a single stick of RAM, your video card, and a keyboard hooked up to get into the BIOS, nothing else [but obviously your CPU & heatsink too...LOL]. You don't need a mouse to navigate the BIOS. You can hook the other stuff up after you get the BIOS stable.
