Stripped CPU screw

[certifiedgmane]

Well... i bought a new CPU to put into my moms dell about 5 months ago i wasn't able to put it in because the cpu heat sink screw is STRIPPED i was able to remove the first 3 but the last one is stripped so badly that it doesn't even resemble a screw anymore and whats worse is the fact that the screw is encased in a plastic cover similar to this http://i288.photobucket.com/albums/ll171/certifiedgmane/intel-core2-duo-cpu-heatsink-fan-dell.jpg so that means that i cant grip it with pliers and that it can only be accessed from the top ...i decided to try to get it out again but to no avail i just gave up fearing that id only be stripping the screw further if i continued. SO! any ideas on how to get this screw out? becuase this is really frustrating me...

THANK YOU!!

Hold or clamp everything securely and then use a Left hand drill and drill a small hole right in the center of the screw. This may unfasten the screw. The Left hand drill is the key to removal.

If not, use a small 'Easy Outer' in the drilled hole and ease the screw out. It will work.

thanks for replying
ok i have a drill so all i need now is a left hand drill bit?

Left hand drill bit, and reverse the rotation of the drill while drilling. This is a common technique in machine shops and automotive repair shops. You may need an "Easy Outer" too, and they are usually left hand spiraled.

Alright THANKS!

Do something sensible for metallic chip control while drilling. You do not want metal chips all over your motherboard especially in inaccessible places. If the screws are brass, the chips are non-magnetic.

O ok thx for the heads up

get dremel>cut slot on top of screw>flathead screw driver>toss HSF. done and done, with little/no risk of metal shavings.

Dremels don't work very well in recessed areas. Take a look at the posted photo.

in spite of the fact that this individual may or may not have more room to work with (as it was specified that the pic was merely similar), im pretty certain that removal of any applicable add-in boards (vid/sound card etc) would make a dremel fit nicely..even without the long flex extension thats availible

I have noted your comments.

I forgot to mention. Always wear safety eye protection when you use a drill. Very important; ask anyone who has one.
