Compaq Presario pops up a system boot menu everytime at startup.

This comes up mostly when it requires a BIOS save. Try that. If that does not help, sometimes setting the default settings and saving will help.

Black screen flashing dash top left corner. ....wont reboot after system restore

If its only 3 mnths old should still be under WARRANTY take it back
if its not under warranty

Turn Off the computer now as soon as you hit the power button, keep on holding Alt key & keep on tapping F10 key ie: Alt+F10, it will open the recovery console select full factory restore and follow on screen instruction. (Note:this will erase all datas on the computer) or

During the boot process you will see on the screen to press a certain key to enter setup usually delete or the F2 key this will differ depending on which bios you have

Press and hold that key during the boot up process to enter BIOS using the arrow keys you can load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart

hope it helps

I turned on my modem, an all that is displayed on my monitor is the blue hp screen. In the botton left hand corner it says <F10=Setup> and <Esc = Boot Menu> and in the right bottom corner, it...

what modem, who's and where, ?
or is modem , monitor?
which blue HP screen there are many,
you left out what it says...
i can not watch you boot, and what is displayed, is key to the cause.

NO OS stated, is this XP?
when you boot, it always prompts in text ,hit ESC key to enter setup"
this is the BIOS hot key prompt that some times shows
a cute small HP icon this too is BIOS created.
then the PC boots and goes to OS, there many OS offered
Windows is XP is one? is it?
or Vista.,w7,/8/10 or PS/2 or linux. HP has many offered OS.
as do Refurb companies endless.

if windows?, the windows log in screen is next.
so my guess is the PC goes to BLUE screen that, before that.
stating (presenting)
startup file failed?
or , HP recover failed.?
or any of 50 other windows blue screens of *****.?
why not post a photo of the screen?
one screen is the XP BSOD , crash screen.
seen here.
one other blue screen is "windows is doing updates" so let it??

one modern HP W10 screen 1 of 50

this is most times below a bad video card driver used on PC.
not matching card to OS. and bam crash.

My computer will turn but it only shows a blank screen with a flashing dash in the top left hand corner. Can you help?

Insert your system recovery disc to repair your startup.

1. Change your Bios to boot from disc:
When your computer powers on, hit F2 (on some computers, F8 on others). Use your arrow keys and move to the right to your BOOT option. Hit the down arrow until you select your CD/DVD drive. Look at the bottom of your screen, and it should say to change the option hit F7 or F8. Use the specified keys, and move your CD/DVD drive above your hard-drive. Save your settings.

2. Boot from your disc. Insert your system recovery disc and restart your computer. Let the recovery disc load. If the option comes up to hit any button to boot from CD/DVD, then hit any button. Once it loads, it should come to a spot where it wants your language, then select the option "Startup Repair". Click on it, and let it repair the startup. Restart your computer, and hopefully it will boot from your hard-drive correctly.

Hope this works.


P.S. If it continues to boot from your recovery disc, then using the same method in step 1, go to your bios, and move your CD/DVD drive below your hard-drive.

Radeon AGP 9800 ati 256 mb

The memory on your card is beginning to fail. There is no repair for it, and it's time to let it retire.

You should be able to find a new 5700 or similar still in most computer shops. Pricing is the big problem with them costing far more then an equivalent PCI-e model.

When i add a memory in damaged DIMM slot showing black screen?

Try moving the working DIMM to other slots, it should work in any slot, if it does, the other ram u have is incompatible or bad

Install a matched pair of DIMMs (equal in speed: DDR266, DDR333, or
DDR400; density: 64 MB, 128 MB, 256 MB, 512 MB, or 1 GB; and
technology: 128 Mb, 256 Mb, or 512 Mb) in DIMM 0 in both Channels A and
B. If additional memory is to be used, install another matched pair of DIMMs
in DIMM 1 in both Channels A and B.
