Major problems, please help!

Hi,

I have just bought a new custom built pc. When it arrived I connected all the peripherals and started to install windows vista 64. I had a bsod during install so restarted it and it then installed correctly. I started installing all the latest drivers for motherboard, gpu, monitor etc. While doing this I had 3 or 4 more bsod of different types. I couldn't proceed more than 10 mins without one. I eventually managed to install all the latest drivers for everything but I still got them. The main ones were PAGE_FAULT_IN_UNPAGED_AREA, IRQL_NOT_LESS_THAN_EQUAL and some othes I cant remember now. Now when my computer restarts my monitor says no signal input. If I leave it a while and restart it sometimes i get signal and can get in (to be kicked out by a bsod!) but normally I get no input signal at all. Any ideas about how I can get this sorted or is it just worth returning it if I can and getting a new one. Specs are

Q6600 @3.01
ASUS SKT-775 P5Q Pro
4gb ddr2 corsair ram
4870x2
Arctic Cooling Freezer Pro
1Tb SATA II

Peripherals (incase they make a difference)

Samsung 2253bw monitor
Razer deathadder mouse
Saitek eclpise keyboard

If anyone can help I would very much appreciate it!

Thanks

Since it's overclocked, does it BSOD when running at the rated speed? What PSU is installed?

It came pre-clocked and I wouldn't know how to put it back. Although now when I switch it on if I can get an input to the monitor it wont get past the asus mobo screen!

Ok, I will give that a go. I am very inexperienced with hardware though so will have to look if I can figure out where they are

Looks like a memory issue to me. Download Memtest86+ and run it for 8+ hours. I guess since you bought the system pre-built you could also take it to whoever put it together and have them test the RAM also.

Yea, it's most likely either defective RAM or the RAM timings and voltage aren't set to the manufacturers specs. Did you happen to check the RAM voltage while you were in the BIOS?

I like to manually set the timings and voltage, but if they're set to auto it may work. If you post the exact model # of your RAM, we can look up the specs.

That narrows it down a little, but there are still three models that match that description and they don't all have the same timings and voltage.

What do the heat spreaders look like on yours?

I reset the bios to default and manually put the ram timings and voltage in. I still had bsod's but mainly memory_management ones now. I took one stick of ram out and booted with windows memory diagnostic tool and it found an error straight away. I swapped the stick and it booted fine. I still get a bsod when I try to start a game but it just says detected a problem and will shut down, no extra info. Then just to rub salt in the wounds on the last reboot it shorted a fuse in my fuse box and now will not power on at all and I have tried various power leads. Guess it's not my day!

Yeah, it cut the power to my mains circuit. I have sent it back this morning. I like learning how to fix things but this was a bit much for a 1 day old machine!
