So i removed the memory cards put one in at a time and my acer extensa 4620 is still going to the blue screen it is giving me error codes oxoooooo4e,oxoooooo8d, oxooo8ef07, pfn_list_corrupt, should i take cards back to store

the main problem why blue screen comes is that if u install a new software and it is not compatible or some software goes wrong.the best way to tackle with blue screen is go to safe mode and uninstall the freshly installed software or programee

check for hardware driver update , run update and scan ur registry using reg in out

Have you removed the memory you added and tried to boot.
If you now have 2 memory sticks have you tried each 1 on there own.
Your manual says you can fit 4gb max installed as 2x2gb ddr533 or ddr667.
Sometimes you do get a bad stick of memory

Here's a link to the manual. All the details you could ever need.

Try looking at this information from Microsoft regarding this issue. You may have an incompatible software driver that was installed when you upgraded or installed / reinstalled some software.

If you wiggle the screen and it comes back, then it is not your Video card. Probably just a loose connection with your LCD cable to the LCD screen. Although you may also need a new screen/cable.

The weird thing is that it "fades" out... which would indicate a bad screen to me.. but securing the cable is alot cheaper to try first.

Completely rule out your graphics card by connecting your laptop to an external monitor... if it works fine for a long period of time then your card is fine.

Good Luck.

Hi shaikh_shaha

Can you get it to boot using any of the options it gives other than boot normally? If the blue screen is caused by hardware then installing xp will still present the problem. If the blue screen is an operating system crash then using the recovery disk or doing a repair install will solve the boot problem.

If you still rather install xp then you need to go into BIOS and set 1st boot device as CD. To go into BIOS you will need to press F10 or F2 (usually) as displayed on the splash screen when you power on

Does this help?

The Blue Dump or Blue screen problem is related with RAM.
1. Try by Cleaning the RAM and RAM slot
2. Try changing RAM
3. Also try changing HDD cable

Hi Lavanya,
Some machines can't read large capacity Sd cards my old Hp Nx6125 could only read max 1Gb. If your card is larger then you may need to purchase an up to date external card reader, most read up to 8gb and are not expensive.
Hope this helped? if it does please remember to press the Blue button for my FREE effort!

Best guess would be to update your graphics drivers. Check the acer website under the support section.
