I have a 2-3 year old HP DX2080MT which was working fine till now, except for a known problem that we could not use pen drives on the USB ports (used to crash). Well, yesterday I must have forgot and plugged a pen drive in to the front panel USB and immediately got a blue screen (running WindowsXP).
Now the PC will not boot at all, not even the BIOS screen (no video signal). When I press the power button the power comes on (fans, lights) but no boot and not even any system beeps (I removed RAM, mouse/keyboard and HDDs). Removing the battery did not help either.
Really appreciate any help getting out of this. Thanks.
The power supply is fine, in the sense that when I pres the power button, the fans come on and the LEDs on front panel also and I hear the disks spin (though no access). So I would say power supply is OK no?
I'd try once again to boot with one stick of memory, then the other. As a last ditch effort, you could remove the mobo from the case and run it (on a non-conductive surface) in case there's a screw loose rolling around that has shorted something.
The form factors are not standard for desktops. If your form factor is BTX, you're screwed unless the manufacturer will sell you a mobo or you can buy one second hand. When you look at a BTX mobo from the backpanel side, the expansion slots would be on the left.
More likely you have an ATX form, with expansion slots on the right. Next is to determine microATX (mATX) or ATX. mATX is 9.6" square and has 4 expansion slots. ATX is 9.6"x12" and has more than four slots
You'd need a mobo that supports your cpu (I still don't know what that is, or have forgotten lol), and supports bothe IDE and SATA. Post your cpu and tomorrow night I'll see if I can find one.
Asrock is a "value" brand made by Asus, one of the top two mfgers.
But installing the new mobo will bring its own issues. You will need to reinstall Windows, and you probably have just a "Recovery Disk". That disk basically restores the hard drive to what it held when you bought it. Since the motherboards (chip sets) are different, there is no guarantee you will have a working system. Even if it works enough to install new chipset drivers, the PC may suffer performance issues unless a fresh OS install is done.
If you have (or can borrow) a real Windows XP disk, you can use that to load the operating system and use your own key (a sticker somewhere on your case) to activate it.
Otherwise, you need to buy a new copy of an OS. That's about $100.
If you want to proceed, I'll need your exact cpu model and a measurement of your motherboard so you don't buy one bigger than you can fit in there. Also, you need to verify that you do not have more than two IDE devices.
Keeping in mind that the mobo may not be the problem, the cost of a new mobo (+ maybe an OS), and the "old technology" . . . I don't know at what point you may feel buying a new box is the cleanest, simplest choice. And maybe get your pen drives working too.
