1. Make sure CD is set as the first boot device.
2. When it starts to boot there will be a count-down where you have to hit a key to boot from CD, if you don't hit a button it will continue to boot...

It's an infection, Virus/Adware.

Your system is commencing web activity without your knowledge, that's why it's making noises associated with IE and oppening pop-up windows.

It could be a lot of things, but probably a motherboard or power issue.

At what point does it BSOD? If the drive works in the other system it's probably a matter of defective hardware.

Tell us where in the process it BSODs, whether or not you can boot in safe mode,...

Personally, I'd just replace it. Replacement of an optical drive only takes a few minutes and you can get a DL DVD burner with lightscribe for $25 dollars shipped. Use this as an excuse to get the...

The drive has either failed or been disconnected. It's one of three things;
1. Your hard drive controller has failed.
2. Your Hard drive has failed.
3. The connection between your drive and...

This is usually a defective hard drive, so it's odd that it would come back clean. I would suggest:
1. open the case and re-seat all the cables.
2. reset your BIOS manually by unplugging the system...

I suspect that the consistently high temperatures of your GPU have just worn it out.

I think it's a video card issue of one form or another. We might be getting blinded by your high temperature, and overlooking a more fundamental issue. Maybe there's a defective card that's failing...

Is it showing any BIOS information on the screen? If it's not and you must have blown the motherboard when you were replacing the ram. This almost never happens with a simple ram-replacement, but...

That is very hot, there's no surprise that it's failing. Obviously an after-market cooler would help, but the stock should work as long as you're not over-clocking. If you're hitting temperatures...

We need more details.

How long has this been going on?

Did you recently perform updates or install new software/hardware?

What are your system specs (not necessarily relevant to the problem,...

LOL, I'd guess that you have a 15.4" or smaller laptop with no dedicated numpad. I don't know why it would be "B" and "N" as they're a row too low but see if there is a function key (usually a blue...

The problems could be virtually anything, but I think that 1400rpm is very low for a CPU fan. It sounds to me like you replaced a dead heat sync with one that's not performing properly.

If...

When you load with the recovery disk does it recognize the Hard drive as being installed?

Could be a bad PSU, but I'd guess a failed motherboard, that's usually the case when a previously working (IE: properly configured) system just stops posting out of the blue.

Could be a defective motherboard, do you have the system speaker or LED diagnostic panel hooked up to receive post messages?

I've had this happen when I forgot to connect the 4-pin power cable for...

I just ran across this problem a few weeks ago, It could be a bad drive.

Drives handle CDs and DVDs a little differently; it is possible, although not common, that the drive will stop reading one...

The specific software is very expensive and graphically intensive. Which makes a second license unapealing and remote desktop difficult. I wouldn't want to try to do professional level photoshop on a...

I'd guess a bad mobo that damaged a stick of ram or bad ram that damaged the mobo. It would explain why you apparently have a defective ram chip and mobo.

This is going to be a little tricky, Photoshop and dreamweaver aren't great programs to use over remote desktop because you get a lot of lag running the connection at that high color quality. It can...

Not for gaming, vista x64 has issues with gaming. But if everything works fine in 32-bit I'd say it was a driver problem.

Could be a short in the motherboard or PSU, either from installing the new fan or whatever burned it out (probably not the latter if you were able to shut-down after it went out). Make sure you...

If it's not posting, and nothing is loading I'd say it's a bad Motherboard. Only good way to test that without equipments (aside from eliminating other likely components) is to try everything on a...

Are you using a premium version of Vista? Drive encryption could cause this. I've never seen what happens when you enable drive encryption but that would be my best bet.

If you are using vista,...

If it's new hardware you should almost hope it's a hardware problem. If there's some kind of incompatability with the OS you'll have to wait for a fix. If it's the hardware you can still exchange it...

It depends on what software you're talking about and what you need to do with it. Can you give us specific examples of the programs you need to use?

Some software can be used off of a flash ...

It could be the PSU, You should have about 100W of cushion on it, but if it's failing it might shut down your system when under heavy load, since that video card uses a lot of power.

The other...

If you look at it in good light (or shine a flashlight on it) can you see the screen image, or is the monitor completely off (it might just be the back light that's not coming on)?

First check...

I'd think it's the PSU, You're really pushing a 600 watt PSU (Neweggs simple PSU calculator says your set-up uses 615 assuming one HDD, which means you should have atleast a 650-700 for safety).

...

Switching power supplies, or using a PSU tester.

A lot of local computer shops will test a PSU for free if you bring it in, since it takes less than two minutes and it's a good way to get a...

Is the disk still in the drive?

Try hitting Delete at the post screen and see if you can change the boot order away from the disk, or disconnecting the dvd drive to let the system boot without the...

So no BIOS access at all, you wouldn't be able to flash BIOS from the CD because it's not loading far enough to boot from a disk. Did it respond the same way with the new ram? (aside from the first...

When you say it wont boot to bios do you mean:
You can't access BIOS settings

There's no BIOS information desplayed on boot (blank screen)

You can't boot past BIOS

Are you very experienced...

If you need it for graphics you need a good card.

That's a great card, if it's in your price range. It's always god to talk about what you need from the start, rather than just what you think...

The new drive is very simple, open the old computers case and find the drive. It will be a 3-1/2 inch drive, meaning it's roughly the side of a floppy disk drive, 3.5"x5(ish)x1. unplug the cords and...

PS: I looked it up, you get pretty noticeable performance increase with that card, but if you wont be playing games (or running the vista aero features) I'd still suggest setting the video card aside...

I wouldn't buy that Hard drive, go for a seagate or western digital, you'll probably save $10 by going with excelsior which is WAY less than the trouble if you ever have a data loss from the cheap...

External hard drive should be fine, file corruption shouldn't spread from one drive to another, and if there were a virus infection on it it would be benign unless there's an OS installed or another...

If it's still under warranty you could probably get it replaced by Dell, but that would be all about getting the right person on the phone and saying the right thing. If you pursue this be sure to...
