Have I static damaged this PC?

Hiya guys, I feel as though I've let myself down having messed up such a simple job, but here goes.

I recently built myself a new PC, a wonderful powerful gaming PC that works a charm. I thought i'd be nice and donate a few of my old PC's components to my Mum's PC, double her RAM, a newer graphics card etc.

So I did, and on booting I just got a black screen and the front LED just blinked away. Panic began. I took out all the new bits and put her old stuff back but the same thing happened. I switched the video cable from the graphics card to the motherboard VGA and got a solid front light but still no picture. The monitor is receiving something as it registers as having signal (no signal icon disappears).

After a few resets it did boot into windows but was super slow, noticeably slower than usual, and then on reset it went back to black screen.

I decided i'd just give her my old PC as it was only gathering dust anyway, so took the bits and her hard drive back home to put in, and i'm now having the same problem with my old PC.

Could it be I've managed to damage something with static? I didn't use a static pad or wrist strap (something i'm now kicking myself about) but i did the usual touching something metal to disperse any static before touching anything delicate.

I can save her data with a hard drive USB SATA dock into my newer PC (not risking another PC) but means i now owe her a PC. If i can't fix this i'll just do that but has anyone got any ideas? Everything powers up, including graphics card fan, hard drive spinning etc, but not even POST is coming up. I've even tried booting with no RAM, hard drive or graphics card to take them out of the equation, just to see if i can get into BIOS, or even POST.

I've built and worked inside a PC so many times but have never run into this before. Hope someone has an idea.

It could be that you not only have hardware issues but have run afoul of MS licensing restrictions. You can't move a hard drive to another PC unless it's a full retail version of Windows (XP and up) and will experience driver problems no matter what.

when you move drive between PC's

You must also install all the proper driver files for that particular PC, it's motherboard. For all I know you moved a drive from a computer with AMD processor and control chips to one with intel processor and control chips.

Don't even get POST

Hiya, I can't install any files as the PC doesn't even display an image...

back to basics then

In reply to: Don't even get POST

only a motherboard, a stick of RAM, and the CPU (with HSF on it), everything else unplugged and all out of USB drives. A keyboard, and a cable to the monitor (preferably VGA). See if you get the POST from BIOS then. Also, short the CMOS chip, or replace the CR2032 battery, just to make sure that's not part of the problem.
