I messed things up.....

My pc has a dual core processor, I wanted to upgrade to a quad. So I bought a quad core processor and a new power supply (first I had 350 Watt, now 430 Watt), since the quad core needed more watts.

Then I started unplugging my old PSU and plugged in my new PSU. Before installing the new processor, I booted my pc to check if the PSU worked. My PC only made a very long, constant beep. I ignored that and installed the new processor as well. It still made the beep sound after that. So I unplugged everything, excluding the graphics card (forgot that one), and it still beeped. I'm afraid my graphics card died :(

Then I turned everything back to normal, old cpu, old PSU etc. And it still beeps! I think I completely messed up my computer :/

Any ideas? Help would be greatly appreciated!

Update: my graphics card is fine, I just didn't plug it in correctly. (It needed 2 connections, I only connected one). Now it works again, with the new PSU. But when I want to install the new processor, it boots, recognizes the quad core processor, but after a few moments my pc shuts down, sort of. The light at the power button stays on, the light on my keyboard too. But the screen stays black. Pushing the power button does nothing, even holding the power for 5 seconds doesn't do anything. Only powering off the PSU seems to shut it down....


Update: with the new PSU, and the old CPU, it works fine but it can't read my hard drive for some reason. It says either:
A disk read error occured
Or:
Error loading operation system.

What cable do I have to use for the hard drive (SATA)


Here are some specs btw:

Old cpu: intel core 2 duo E8400
New cpu: intel core 2 quad Q9450
Old PSU: I don't know
New PSU: Corsair CX430
MOBO: asus p5e vm-do
GPU: Ati radeon HD 5850 1GB
6 GB RAM
Windows 7 64 bits

Another update: I tried formatting the drive with a sata to usb device, it didn't work. Also; it says the filesystem is RAW, instead of NTFS :/

Are you absolutely certain you have everything plugged in as it should be? You should have at minimum a 20-pin power connector for the motherboard and a 4-pin power connector somewhere near the CPU. Sometimes you have 24-pin for the motherboard and up to 8-pins near the CPU. Take another look if you're unsure, to verify you didn't overlook a small power plug somewhere on your motherboard.

Sometimes a BIOS update is required when installing newer processors. If there is a BIOS update available for your motherboard, it may be necessary to reinstall the original dual-core, update your BIOS, then replace the quad-core.

At the very least, you can confirm that your new power supply is running correctly by using the original processor as...

Specifically, which processors, both old and new, and what motherboard?

When installing things, do not ignore warning sounds. They are there for a reason.

That was exactly what I was thinking :D I'll try updating the BIOS tommorow


I'd like to thank you all for the replies so far! :)

Check the manufacturer website for your Make and model of the motherboard as to whether the cpu is supported in the CPU support list, if it issn't listed then you cannot use the new cpu for that motherboard, which is probably the reason for the beeping.

You should list your make and model and speeds and watts etc for all your hardware so repliers can assess the actual the compatibility of your choices.
 
Actually, the beeping issue was solved, TenPc, but now the system powers down shortly after powering up and identifying the quad-core CPU. If we had the make / model of mainboard, specs could be checked. I am wondering if the quad-core requires more current than the board was designed to handle?

That's why I initially asked for specific part ID early on.

I do tend to jump the end bits of the details - OOPS!
The OP stated "first I had 350 Watt, now 430 Watt", I hate that cx 430 watt PSU, everybody thinks it's the "ants pants".

So, to the OP, what is your make and model of the video card? If it requires 2 power connectors then it's not going to be some low end video card, it will also require power, possibly as much as 225 watts for maximum requirement. The CPU might requires 130 watts, so that is 355 watts so far excluding all other hardware.

The cx430 V2 only has 336 watts on the 12v rail.
 
The original 350 Watt power supply was running the same graphics card, with a dual core. If it's an older AMD dual core, I know they had those up to at least 125 Watts at one point. I kind of doubt his new power supply is lacking enough oomph to get the job done with a mere 2 added cores. I have had plenty of trouble with older ECS motherboards however, falling over with even a 95 Watt processor in them. They would do almost exactly what he mentioned. Run, for a random amount of time, then suddenly not be running.

"It needed 2 connections, I only connected one"

Since when did the average 350 Watt power supply have PCI-e power connectors? I'm going to wager a guess that the graphics card does not have dual power connections on it but that the OP has a dual-Molex to 6-pin adapter, and he only had a single Molex connected.

I reckon he's fried his video card or his motherboard or possibly both, and is only noticeable when the OP is in full use of the system. Sometimes you don't noticve anything wrong until you need that extra power.

Sorry OP, are you still there?
