i just put together a new computer, specs:

intel 8400, radeon hd4850, 4 gigs ddr2 800mhz (only have 1 stick in for troubleshooting purposes), PQ5 motherboard

when booting, this screen comes up

if i wait about 5 mins at the above screen, it will continue. i can enter bios or attempt to boot windows.

if i enter bios, bios will load and i can modify them, although the bios screen is EXTREMELY laggy.

if i boot windows, eventually the windows boot screen will come up, and then it blue screens with a "irql_not_less_or_equal" error.

thoughts?

I think you need to have either 2 or 4 sticks of mem on your board at one time.

and your motherboard is a p5q not a pq5

[jdob22]

thank you for your response

i tried with 2 sticks initially, before going to 1 for troubleshooting

No board will require more than one RAM stick to boot. This sounds like an issue of unstable RAM. This could be because the RAM is faulty, or because it is undervolted. What RAM do you have?

i tried first with mushkin 800mhz ddr2, and then with ocz 800mhz ddr2

possibly its a psu issue? i have an antec 430w true power trio powering radeon 4850hd, intel 8400, 1 160 gb sata hd, and 1 dvd/cd rom drive...

or possibly the ram slots on the mobo are bad?

Can you give the exact info about your RAM, such as model number? With this information, we can determine if your RAM voltage needs to be raised, and if so, to what amount it should be raised to.

thanks for your help

look in the mobo manual in the power connection section...make sure the AUX cpu power connector is plugged in...same for the video card connector...
did you put thermal paste between the cpu and heatsink...

aux powers are connected, thermal paste? aren't new cpus pre-thermal pasted?

[happyrock]

nope

[jdob22]

nope

ok, well plan is to pick up a new mobo from fry's for troubleshooting. i'll grab some thermal paste well there. i'll thermal and reseat cpu on current mobo. if this doesn't work, i'll assume that something is bad on the mobo, probably the ram slots. i'll swap the mobo out and if all goes well, return defective one to newegg. if swapping mobo doesn't fix it, what next? cpu?

[happyrock]

get a mobo thats compatible with both your E8400 and the RAM you have...be sure to check at mobo manufactures site on the approved ram

I don't have time...you can do it...read about that mobo here
I was not telling you to buy new ram...just make sure the ram you bought for the asus board
is compatible with the new board your going to buy...
