Hey everyone! I've just finished putting together my second build but i seem to be having a few problems. The system seems to turn on just fine but the whole computer will shut down after about 15-20 seconds. I can enter the mobo setup screen but this doesn't seem to make much difference. Originally i thought it was probably a PSU error so i replaced it and still have no luck. I've so far tried re-orienting the RAM, disconnecting hard drive and cd drive and trying to boot as well as clearing my mobo CMOS. So far nothing has helped. Any help i could get would be MUCH appreciated.

The setup as of now is:

Asus P5N-E SLI
Intel Core 2 Duo E6400
XFX GeForce 7900GS
Patriot 1 GB (2 x 512) DDR2 800
MasterPower 500W power supply
1x40 GB SATA
LiteOn DVD/CD-RW combo drive

Hi & welcome to HTFC sounds almost like a thermal fault dosent it?

Did you know that you can get bios to boot and get to the bios screen with just the bare bones, with just the CPU, RAM & Graphic card everything else can be disconnected inc. the hard drive, doing this would eliminate these disconnected items, if all else fails doing this might prove a point.

Supposing everything was ok at this stage and it booted, it would ask you to 'Insert the disc with the operating system on' or something to this effect.

But first I would double check everything the mobo switch or link speed settings, ensure the fans are rotating and ensure all the earthing screw are grounding properly, more so double check the wiring from the power switch to the mobo's.

You're probably gonna 'tell me to 'get lost' if I asked did you install the CPU properly and used the correct thermal paste made specially for CPU.

You would expect on a working mobo a RAM or graphic card fault to get a series of bleeps indicating an error code, just wondering if it's worth checking that these are ok and inserted properly.

Hoping this will throw some light for you..... these are the thing's I would consider myself as it seems a logical approach.

Your first goal is getting it to boot into bios.

heh, thermal paste? Is this something i would have needed to purchase seperately or would it have come with the heatsink/processor. there are several strips of some kind of thermal material attached to the bottom of the heatsink (thermal interface material is how the instruction manual refers to it). Is this what i need (I just rechecked and i did not recieve anything of the kind with my cpu. Here's where i got it (newegg.com)?

One more bit of new information. After recognizing that i hadn't installed the mobo speaker (heh) i corrected the issue. Now i hear a series of 4 beeps (same tone) before it shuts down. I believe this is due to the checksum error.

(Also i did attempt the barebones boot earlier with no success. All fans seem to be running fine. I don't know if i mentioned that earlier)
