Hi all,

Mate got a new build set up but is having problems, and not sure how to fix it.

Specs:

8800gt
E6750
2x1gb Corsair XMS2
P5N-E SLI

He Presses power button and says it just turns off within 5 seconds and most of the time it doesnt show anything on screen, but a few times it has flashed up with the asus logo. Checked all connections lots of times, don't know what to try :/

Any suggestions for us to look at?

Thanks :)
 
Try all the normal things:
1) Try one stick of memeory in all 4 seperate slots.
2) Reset the cmos
3) Make sure all power cables are where they should be (also the common forgetting to insert the 6 pin lead into the GPU)

What power supply is he running?
 
Not able to check the ram and clear the cmos right now but will do.

He says Power Supply is 500W but doesn't know the make (eek lol).
 
OK says he has swapped about the ram etc and reset cmos but now says it randomly freezes when booting on bios, said it also tries to load windows sometimes but flashes with a blue screen and then pc restarts.

He needs to reformat hard drive and reinstall, thats the cause of the blue screen ;)

Any suggestions?
 
surely the blue screen is from a hardware failure? dodgy settings in the cmos etc..sounds more like it's overheating or the ram is borked, just a stab in the dark tho.

what beeps does it do when cold starting ?
 
The usual 1 Beep is what I have been told. Anyway he said the freezing has stopped but he can't boot into windows (trying to use old hard drive with it installed already) so I have told him to try formatting, could be working now. I will update.
 
Ask him to go into the bios and check the voltage for the memory. If its set to auto then tell him to manually set it to what the manufacturer wants it to. I think Corsair XMS2 is 2.1v but dont quote me on it.

The P5N-E boards are excellent but they do sometimes have a mind of their own when setting voltages on memory.

Has he got the CPU on stock settings also?
 
Right he has tried manually setting the ram voltage. But did not make a difference. It freezes randomly, he managed to format, but it freezes whilst trying to install windows half way through. Sometimes it won't even turn on and takes a lot of tries.

Any more ideas?
 
Have you checked to see if the hsf is attached properly onto the cpu? Check the cpu temps in the bios too.

Any details on the make and model of the psu?
 
All you want it to do is post and get into Bios. Does the board have on board graphics? It would be annoying to spend ages fault finding only to realise your dvd or hdd is busted or overloading the PSU. Maybe the GPU is causing problems.

Your mate seems to have tried the basics. I would stip it bare and start slowly.

Oh and I omitted the heat sink cos I thought that would be obvious......ie leave it on please
