[SPLIT] Windows Update error code 80070490, help!

[pedro]

Keep trying to get to a point in the startup process where it can load the memtest86+ disc I burned but no luck.

If I run Startup Repair like it prompts every time I startup, it completes it and gets as far as the login screen or desktop, but crashes to BSOD before it has chance to load the screen properly - or I get chance to do anything.

If I choose not to run Startup Repair and launch 'normally', it keeps running black-screen CHKDISC but crashes every time due to "an unspecified error occurred"

Latest BSOD:

SYSTEM_SERVICE_EXCEPTION

Trying to launch in Safe Mode now to give memtest86+ a go, but it's not looking good...

Hmm, I'm just going round in circles with this start-up crashing. Sometimes I can get limited use before it BSOD's, sometimes not.

The memtest86+ cd burn wouldn't run on the system (but I'd only screw up the memtest86+ memory module tests and break the damn thing anyway, I'm no repair-man!)

On the occasions when it does load up I seem to able to use Windows Update again, but it refuses to install this one update: KB967723. It gives me the same error msg as what originally brought me here: 80070490 - so I guess that one's just not happening, even after all the fixes.

I downloaded it manually from Download Security Update for Windows Vista (KB967723) from Official Microsoft Download Center - but it says it's not valid for my system (!) so I'll have to press on without update KB967723. I may get a few more sessions out of it, maybe not.

Thanks so much for your help though, I know it's a busy week for ya.

Luckily I don't have anything important saved on there. All my stuff's on my old(er!) desktop pc and backed-up fully, so I can work on that for now.

Like I said, it was time for a Macbook upgrade anyway so I think I'm gonna write off Ol' Black and thank him for 4 years' dutiful service.

Thanks and all best Tom!

Cheers, Pete
