pc wont boot up

April 25, 2010 at 12:12:09
Specs: Windows 7 x64, ram 6gb
I'm having what appears to be a major problem with my pc. I have an Hp Pavilion elite m9350f, and i recently moved it to a new case and added a couple case fans.I also installed a new graphics card nvidia xfs 250. I had a new power supply as well, but it died within an hour. So i put the old power supply back in and things were running fine for several weeks. However whenever i would boot up i would get a " system fan error" press f2 to continue. my roommate assured me it wasnt a problem. i would hit f2 and the pc would boot up ok. this morning i woke up to find that my pc had restarted itself during the night. it was sitting on the "system fan error" screen. i hit f2 as usual but nothing happened. after holding it down briefly, it took minute or 2 for it to progress. however my pc gets stuck on " detecting storage devices". it sits there and refuses to progress. i cannot run the diagnostics or anything off the HP boot up menu because the "system fan error" comes up to quickly. I would greatly appreciate any help or suggestions. I already tried to clean out the power supply fan, but it failed to change anything.

Why would you transfer OEM hardware into another case?

The fact that the new power supply burned out quickly tells me that you bought a cheapie. Generally speaking, a decent quality units costs at least $50 & you have to pay close attention to the amperage specs, especially when installing a gaming card. The GTS 250 is a power hungry card & is rated at 150W under full load.

There is no "nvidia xfs 250" so I assume you have a GTS 250, possibly made by XFX?

The "system fan error" refers to your CPU cooling fan.

According to what I found at HP.com, your system originally came with a 9800GT? If you replaced it because it was bad, fine....if you bought the GTS 250 as an upgrade, you probably wasted your money. You will see very little performance difference, at least not enough to justify spending over $100.

the old 9800 burnt out so i replaced it with the gts 250. i only spent 25$ on the power supply. i moved everything to a new case because i started to have heating problems in the old one. if the error refers to the cpu fan it dosent make any sense. the cpu fan appears to be running fine. no erratic spinning that i can detect by watching it.

Make sure that the CPU fan is connected to the 'correct' (CPU) connector.

"i only spent 25$ on the power supply"

That's why it fried within an hour. You're very lucky you didn't burn out your video card or motherboard.

The CPU fan is attached directly to the heatsink on the
motherboard. Thx for the tip on crappy power supplies.
What do i need to fix/replace to get my pc up and running?

I'll try again. :-)
Make sure that the CPU fan's 'cable' is connected to the 'correct' (CPU) connector on the motherboard.
If it's connected to the wrong connector, that would explain the 'system fan failure'.

I found the cable, and it appears to be in the right spot, I don't
know if it got unplugged while tramsfering.It plugs into a 3
prong male slot. I only see one other slot where it looks like it
might plug into. The 2nd slot is brown, just like the end if the
cable. The slot it's currently plugged into is white. I didn't try
changing the slots. I did try booting up to see if inwoukd get a
different message. This time it told me that no CPU fan
detected and it immediately shut itself down

Check your manual to find out where the 'CPU' fan should be connected, and where the 'system' fan should be connected.

The cable from the CPU fan cannot reach the 2nd slot, I
plugged one of the case fans into the 2nd slot and it doesn't
give me the system fan error, but it sits on the hp start up
screen for a minute before progressing to the "detecting
storage devices " screen. None of the start up menu options
work.
