well if you disabled system restore then no wonder you cant use it, you mentioned it happens when you run "almost all programs" can you be more specific? provide the names of those programs,
also provide full system specs including psu brand/model (look on its sticker if you dont know) , you added new hardware recently before it started?

, get into hardware-->mainboard ,scroll down til youll see temperature/voltage sensors and take a screenshot
check the mobo for bad capacitors and better use a flashlight cuz its kinda dark in there , see examples
if youll find any rma the mobo if still under warranty , otherwise have em replaced at some electronic repair shop shouldnt cost much
as for the ide cable , ide hds run at ata100/udma5 or ata133/udma6 (maxtors only) , a 40 wire (or conductor) ide cable limits to ata33/udma2 which is fine for most optical drives but it severly limits the hd performance (and when it comes to burners an 80 wire will make a little improvement in burning quality over a 40 wire) , as far as i know 40 wire ide cables are no longer being manufactured but some stores still have em in stock , goto some local computer store and get an 80 wire ide cable and youll notice big performance boost , 40 & 80 wires ide cables have diffrent color coding , on a 40 wires ide cable all the connectors are black & on a 80 wires ide cable the connectors are blue/grey/black
