odd issue with ps3

[Chewie]

after the previous issue with my ps3 where it would crash when installing resident evil 5 (http://www.indianvideogamer.com/forums/index.php?showtopic=35344&hl=) i continued using it & it would work ok. then last month i got psn plus trial & downloaded & played limbo, quantum conundrum & vanquish ok . then i played sleeping dogs & even that worked fine for a while till a strange issue crept up.

every time i loaded the game it would crash & the red led light would blink. then when i restarted it, it would perform a file system check & then would work fine. this process of load game for first time - crash - file system check – game working ok happened every time with sleeping dogs.

then i bought & installed dead island digital version from psn & this crashed on loading into the game too but this time even doing the file system check didn't help & as of now its unplayable.

i'd also bought assassin's creed brotherhood & revelations double pack (physical disc version) which has a 8gb install of the game to hdd & this worked ok for about 30 minutes then started crashing especially at cut scenes & when loading next section after ie. at check points.

thinking that my hdd was at fault i changed to a new hdd, formatted it, did a system restore & re-installed assassin's creed & dead island but the same problem persists so its not a hdd issue. nor is it a ylod coz the yellow light doesn't blink before.

also games that dont install any data on hdd work fine & so do demos & games installed earlier.

while looking up the issue i came across this video --

which involves adjusting something called the trim pots in the power supply section. apparenly the first slim models (which is the one that i have) have this problem. but it doesnt feel like a power supply issue coz if i play other games or just leave it on it works fine & the crash happens even after just starting the ps3 so its not like it getting hot or something.

has anyone else here with a slim faced this issue or tried this fix ?

seems like there's an issue with the hardware component that reads/writes to hard drive (but then even downloading/installing digital games should be a problem, no?)

Bro change power supply cord put it tightly power souce and ps3 and plz chk power source socket is working fine or not then see if u ve the same problem

ya bro checked those things & also tried with different power cord but same problem persists. besides, some games run fine & if it was caused by something like that ps3 wouldnt work with any of them
