Keep Rebooting

Hi all,

I was trying to build a PC. Bought motherboard, cpu, hard drive, memory, and video card. Use old dvd rom pulled from my old one.

Everything is new. When trying to install vista, I just couldn't do it. Computer keeps rebooting or hangs when cd rom is copying file to initiate windows installing (the very first step!!). First I thought it's the motherboard (Abit 190HD) problem, so went exchange one. Same problem. Then returned and bought an Intel motherboard. Still the same problem... Now I start to doubt I did something wrong instead of the motherboard... Hope this is clear to everyone.. Help please.......

 

Did you place the moptherboard standoffs in the correct locations? If not you will cause the board to short against the case.

 

Yes. Will it be caused by cpu, memory, or other parts instead of the mobo? I start to question about anything now....

 

When you removed the CPU and installed it on the other motherboards, did you replace the thermal compound layer in the gap under the heatsink. There will be temperature readouts in the BIOS/Startup settings.

Check the Intel website and that of the RAM supplier, that the model of RAM is compatible.

You can set the motherboard up outside the case on the antistatic bag or box that the m/b came in. That will rule out a short.

Did you follow the manual as you built it? Have any power connections been missed? There should be extra connections to the m/b and graphics card.

The power supply is adequate? Are all the connections fully seated?

If it is WindowsXP you are loading I would download the MS boot disks floppy or CD and use them to start with, 6 floppys it worked for me in a similar situation.

 

1) The thermal compound was placed. I checked the tem in bios and it's not overheat.

2) My mobo is Intel DP35DP and the rams are Patriot 6400 1GBx2. They should be compatible, right?

3) I did follow the manual closely when built it.. There are two power connections to the mobo. 1 is the 4 pins and 1 is the 12x2 pins. I don't see power connectors to the graphic card.

4) The power supply is also new. 450w Rhino.

It's still hanging and rebooting... I took the board back to Fry's (where I bought) and talked with the guy who helped my purchased all the stuffs. He's saying that now we may rule out the mobo problem and start doing swaping, which means to place new cpu and ram to see whether they work... It sounds a lot of work to do that as I've already gone back and force to Fry's 6 times in three weeks!! Any thoughts?

 

sorry, you did say it was Vista, I would try if you can get one to load XP, would eliminate Vista incompatibility.

 

I did try using my old hard drive that's loaded with xp, but it still doing the same thing. It's good through the Windows XP screen and then reboot. After that, it's the menu screen asking whether to start windows normally or in safe mode. Tried both and they all re-boot....

 

I can't see that m/b model listed at the Patriot website:

Check the manual for the graphics card. Mine has a special PCI-E power connector.
