    Well I really screwed up tonight. I was attempting to remove my old power supply and managed to strip out the back left screw. These guys were in real tight, none of them came out easily. Any suggestions to removed the stripped out screw or am I stuck using a dreamer to cut in a slot to fit a flat head.


    Update: I bought a screw extractor bit and managed to removed the stripped screw manually. The replacement power supply seems to be working fine. Thanks everyone.

    Those screws are not Philips I believe but probably Torx. Are you sure it is stripped?

    You need an Allen Key. I think 3mm off the top of my head... Deffo within the 2.5-4mm range.

    If it is totally egged out. Drill it off. Carefully as to not damage the circuit board. Then vacuum very thoroughly as to not leave any debris. Although removing everything else before drilling and vacuuming would be preferable.

    Needle nose vice grips. If not then drill it out. But it would be best to remove everything prior this way you minimize scrap metal shavings from frying your machine after boot up.

    Yeah it was a hex bolt. I was an idiot and tried removing it with my screwdriver kit. I was using the right size of bit, but the angle with the screwdriver handle wasn't 100% straight on. I should have went and grabbed my allen set.

    I was thinking about getting one. I wasn't sure if I would have enough room to use it correctly. I know I wouldn't have enough room to use a cordless drill, so it would have to be manually.

    There are hand operated versions of those extractors. I've actually never used one of those before, but I've always been curious how well they work.

    How badly did you round off the head? There is some compound on the thread of the capscrew, but not enough to warrant drilling or using an easy out/stud extractor to remove it.
    Could you not just get a small flat punch, a small ball peen hammer, give the dome-head a tap, then use the correct Allen key to move it?
