Black Screen on Startup, No BIOS

March 30, 2011 at 12:53:11
Specs: Windows Vista
It first started with error messages. I would get this "Interactive logon process initialization has failed. Please consult the event log". I only got this message once and just ignored it because it never happened again.

The next week my screen went all pixelated and the computer crashed. After turning it back on, I got the repair windows with boot disc option with a "Status 0xc000000f Boot selection failed because required device is inaccessible."

I didn't have the boot disc so I restarted in safe mode, couldn't figure out what could be wrong, then restarted in normal mode, and everything seemed fine, until it went pixelated and crashed again the next day while running a virus scan...

After that, when restarting it wouldn't even run BIOS or anything. Just a black screen, no mouse, no F8 F2 or F12. So I checked the display with an external monitor, nothing. I let it sit for a few days, tried it again, and I was able to get BIOS and start it in safe mode, which is where I am now. I'm running another virus scan and CCleaner. It has detected and deleted 3 trojans (1 looked liked it might have been a real virus [exploit-byte verify]). The whole time I've been in safe mode, the screen has been pixelated with thousands of yellow squiggly lines.

Does this sound like the graphics card is failing? Or maybe a combination of the graphics card and a trojan? I've been having problems with the fan and I've learned that NVIDIA has had significant failure rates with card over-heating (no warranty). I'm using a HP DV9700.

I just had a similar problem with an HP Pavillion DV9500 & it turned out that someone installed mis-matched memory. It drove me nuts for 2 days. I even changed the CMOS battery, think it was that.

It still could be the video chip. If you can get to F8 one more time, choose VGA mode.

I don't think it's malware.
