Hi - apologies for long post but I've been at this for 3 days now and hit a dead end.
My HP touchscreen IQ520uk has worked well with Vista since I bought it in 2009. But a few days ago I got the blue screen of death so ran a Smart test which said to replace the HDD immediately. Not knowing much about it, I did my research, made an image of the HDD on an external drive and a Macrium rescue disk, installed a new HDD (a 2Tb WD one instead of 320Gb WD one). While researching HDD problems with these computers, I came across a bit of forum chat about the these LCD power inverters giving up so I before I went and bought as new HDD, I took the old HDD out and also the inverter to give it a visual check all looked OK. After install, everything came back up just as before. That was yesterday and I checked everything was functioning then worked / browsed on it for about 4 hours. I then turned it on again this morning and everything worked fine for a few hours and I shut it down again. Perfectly happy!
This evening, I turned it on, used it for about an hour then got another blue screen. No message at the top of it but the technical details said the problem was with usbuhci.sys. I restarted it and got a black screen. I thought it might be the inverter so I quickly whipped it out again and checked all the wires etc. were OK no apparent problems.
Booted up again and hit F10, got to the BIOS this time and ran a short smart test on the new HDD it passed no problems in about 100 seconds. Then I arrowed to the power management of the BIOS but before I could get there, the screen froze. I waited about half an hour and hit various buttons but it had totally frozen. So I turned it off. Its been virtually dead since.
When I power it up, the screen briefly flickers b ut then remains black, the fan starts normally, the HDD spins slowly and if I put a CD in the drive it sucks it in. But thats it. The factory supplied USB key for the wireless keyboard and mouse at the bottom of the machine lights up but none of the other USB slots light up a USB stick. If I insert a CD, if sucks it in, clicks and whirs a tiny bit but wont fire up and if I boot it up with a CD in the drive, again it clicks and whirs a bit but wont start to spin it properly like its booting from it.
Ive no idea if this is coincidence or if I damaged something but I was really careful working on it and I cant see why it would suddenly die after working just fine for 24 hours. The new HDD consumes less power than the old one.
Ive tried putting the old HDD back in no difference, and tried resetting the bios (as per HPs instructions hitting various F buttons in a sequence) and still no difference. It just sits there with a black screen, fan and HDD gently whirring and nothing else. The only reaction I can get is if I pull both the RAMs out, then I get short and long beeps.
And Ive not installed any new programs or gone to any dodgy sites (that I know of) lately.
I thought about buying a new inverter but now I think thats probably not the problem. But Im not sure if the inverter powers other things any advice on this would be welcome. My very limited knowledge makes me think the MOBOs packed up I hope not.
Ive been at this for days now and Im at a total dead end now. Anyone got any bright ideas please?
Thanks in hope!
