98 Oldsmobile Aurora There's a on my Dash it says information center and has the oil fuel speed all that it says low oil is there any way anybody knows how to reset that


Check your engine oil using the oil dipstick located on the engine - you need to add oil to the fill line as shown on the dipstick. You should have the oil replaced regularly (every 3-6 months) and keep your eye on the level if the engine is leaking oil underneath or burning a lot of it.

asus crosshair socket am2 motherboard not booting


Sounds like your monitor is bad. Try another monitor because if the video card was bad and the monitor is working you would get a No Signal message on the screen. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok, then your original monitor is bad. If the Borrowed monitor does the same as your original monitor and does not display anything, then there is an issue with your video card.

HP IQ772 power but no boot


all PC's fail. (Virus is #1 )
what OS (xp,vista, w7) ?
is this PC in UK, England?
HP shows, CIRCA 2007 build, (1st) and is near out of support)
sure... you skipped the first steps.
1: battery out, get it out of the pc.
2: use only he a.c line pack ,
3 it has PSU are all power pins reading correct voltage? must
4: if above ok, the BIOS works, on all systems,

GET BIOS to work first.

do you know your BIOS hot keys, its very important to learn this first
if working on any PC made ever. 1981 to now.

see this yet, the BOOKS

best is not to pull any Cmos battery , just use a volt meter
there, 3v is good, 2v bad. see? or scramble all BIOS setting
including boot drive... arg.

this box has no standard VGA 15pin jack on rear, making
tests with external display hard
use a flashlight pointed at screen see any data
if yes the blacklight in the LCD is dead. (BIOS screens dead)


does boot up, F11 bring up windoz recoverY.

odd machine, wireless mouse and keyboard
the latter begs the question gee how can we get to BIOS
lacking a keyboard, driver in BIOS ROM.
curious ,,, on line i see no body getting BIOS screens.
fresh battery in keyboard,

what happens here.
If the hard drive errors happen before you can get to a recovery screen, try this:
  1. Turn off the computer and wait at least 5 seconds with the computer in a full off state.
  2. Turn on the computer and press the F8 key repeatedly as the computer starts. An "Advanced Boot Options" screen opens.
  3. Select Repair Your Computer and press Enter .
  4. Select a keyboard layout that matches your country/region and click Next .
  5. When the login prompt appears, select the user name with Administrator rights (not Administrator) from the User Name drop down. The user name with Admistrator rights is most likely the first user name that was entered during the initial computer setup.
  6. Type the logon password into the Password field (press Enter if you didn't put in a password) and then click OK .

    A System Recovery Options window opens.
  7. Click Command Prompt .
  8. At the prompt enter: c:
  9. At the c prompt, enter: chkdsk /b
  10. If a message opens saying you need to forcibly dismount the drive say yes.
  11. When it is done, try to do an F11 recovery again.


black screen has many causes.
if its not just the back light dead, use a flash light first
get BIOS to work, do you get F8 or F11 screens
this is key to solving the true cause on all PCs.
one can use a USB keyboard if yous dies.
ask here , on the real forum.

i read your 2 users guides, no one word on BIOS
that is BS. and due to now rear VGA port (has some mini bs jack)
you cant see if the PC is dead or just the silly display or GPU chip dead.,
a preplexing box, i never buy those i get real DT or top HP laptops.
all in one boxes are custom, and tricky to fix.
for sure the nasty VGA trick missing, JACK

monitor problem


If you restart your computer and either go to the Bios setup menu (usually by pressing DEL or some other noted key, in the first few seconds of power up) does the same "contrast" menu still appear?

If so, then it must be your monitor (likely Monitor, not computer)
Your monitor is mad at you and it is displaying a Warning Message that is part of its OSD (On Screen Display). Some monitors are more sensitive then others so it takes very little to get this type of message. To get rid of it you will need to use the buttons on the monitor to get into the OSD menus. You need to look for something like "OSD Settings" or "Warning Message Settings" which may be found under "Setup Menu" or "Options Menu". This all depends on the make and model of the monitor as they are all slightly different.

Once you find this area you will need to turn off a setting that will be called "Warning Messages" or "Display Notifications", again the wording may be different but the idea is the same. Once you find the setting you should have the choice to set it to "ON", "OFF" or to an amount of time it will display (5 seconds, 15 seconds etc...).

On my Viewsonic the setting is found under "Setup Menu", and then I turn off "Warning Notification".


GOOD LUCK!!

ps. If the display looks OK then there is most likely nothing wrong. The message appears because the monitor detects a setting that may be in error. If the message goes away after a bit and doesn't bother you, you may choose to ignore it.
