Please help,

I have vista home premium installed and decided to up my ram. I alraedy had
1gb 184pin 400mhz, and decided to add 2gb more. I installed the new ram but
now when my system boots up I get the error FILE:CI.dll - STATUS: 0xc00007D
Does anyone know how i can fix this
 
sparks99,

I did a google search, and I found a definition of what CI.dll does.
Microsoft states, quote:

'Code Integrity (CI) protects Windows Vista by verifying that system
binaries haven't been tampered with by malicious code and by ensuring
that there are no unsigned drivers running in kernel mode on the
system. CI starts as Windows starts up. The boot loader checks the
integrity of the kernel, the HAL, and the boot-start drivers. After
these have been verified, the system starts and the memory manager
calls CI to verify any binaries loaded into the kernel memory space.
These binaries are verified by looking up their signatures in system
catalogs. Aside from kernel memory space, CI verifies binaries loaded
into a protected process and system installed dynamic libraries that
implement core cryptographic functions.'

Now, why are you getting some error involving all that? I don't have a
clue, but it clearly has something to do with the RAM you installed, it seems
to me. Perhaps someone with more knowledge in this technology can chime in
and tell us. It's over my head.
 
spaarks99,

I forgot to include in my previous comments that I didn't find anything
using google search about the number oxc00007D. Could that be a memory
address? That number looks similar to numbers used to designate memory
addresses, but I'm not sure about that. Anyone?
 
Hi Freddy,

Thanks for your responce. I have just checked again and the error code was
in fact 0xc000007b, which may change what you may think the problem is. Also
I have usb 2 ports but they do not seem to be working right as when i plug my
external hard drive in i get a pop-up say this device would be faster in a
usb 2 port, but is in in one already Any ideas?
 
sparks99,

OK, lets try something more specific. Try checking a Vista report for
specific errors and corrective measures to take: Click on Start (icon) and
select All Programs. Then, select Maintenance > Problem Reports and
Solutions. When that report opens, select
from among the Tasks on the left margin and elsewhere. Here you may see
specific information about what caused your problem. If you get some insight
from the report, take the corrective action suggested in the report, or post
back.

I did another search on 0xc000007d and got lots of hits, so putting in the
correct error code made a difference. The error code means the the
application failed to initialize. I'll check back later about the USB
message. The wife wants me to take her shopping right now. lol
 
Sparks99,

If you are receiving PC messages that state you should connect your USB 2.0
device to a higher speed USB port, and you know that you have USB 2.0 ports
on your computer, there are certain USB controller upgrades that have been
made available through Microsoft Windows Update that can enable USB 2.0 on
your computer. To get these updates use the following steps:

1. Connect to the Internet if the computer is not already connected.
2. Open Device Manager: (right click Computer, select Properties , and then
Device Manager).
3. Click the plus sign (+) next to Universal Serial Bus Controllers.
4. Right click the first USB Host Controller, select Update Driver Software.
5. Follow the information given to download and install any available
updates.
(The Other Universal Serial BUS Controllers should be automatically updated.)
6. Test the USB device again. (If the message still appears, continue
using these steps with the other USB Controllers until the message no longer
appears.)
7. You should also follow these steps with the USB Root Hubs, if they do
not update automatically. Follow on-screen prompts.

If I were doing this, I would first update Vista with all updates available
on the Microsoft update site. I would do this on the theory that the process
might include USB 2 updates. After installing all Vista updates, test the
USB drvice, and if you still get the message, then follow the above steps.

Note, that in order to have USB 2 cabability, you must have a motherboard
chipset that supports USB 2 and also the BIOS must be properly set to enable
USB 2. Also, on some systems, some USB ports may only support USB 1 or 1.1.
If you get the message after doing all the updates, try a different port.

Moreover, you can check in Device Manager, under Universal Serial Bus
Controllers, to see whether you already have USB 2.0 drivers installed. Do
this before trying to update the drivers. If one or more USB Host
Controllers are shown as:

Standard Enhanced PCI to USB Host Controller (it's USB 2.0)

If any are listed as:

Standard Universal PCI to to USB Host Controller (its USB 1.0/1.1)

Note that USB 2.0 has the word Enhanced while the other has the word
Universal.

Another way to check which USB drivers you have installed is the check the
name of the drivers that are installed under USB Controller Properties Driver
tab, as follows:

usbuhci.sys (it's USB 2.0)
usbehci.sys (it's USB 1.0/1.1)

Do these checks before updating. If your system checks out as haveing all
the USB 2.0 drivers installed, then you don't need to update.

Post back if you have questions.
